How Often Should You Service Air Conditioning Units?

Most people don’t think about their air conditioning until it stops cooling or heating (air source heat pump air conditioning systems) properly, becomes noisy or the bills start climbing. The truth is, a simple annual service can prevent most of those issues. Regular air conditioning servicing should be done at least once a year, especially for commercial systems. In this guide, we’ll explore how often to service business / commercial air conditioning units and the simple signs that it’s time to book a service.

How Often Should You Service Air Conditioning Units?

Air conditioning systems with an output over 12kW, are legally required to be inspected at least once every five years, under EPB regulations. However, for the best performance, air conditioning units should be inspected, cleaned, and serviced at least once a year. Regular air conditioning servicing keeps your system working efficiently, improves air quality and extends the life of your unit.

How Often Should Commercial / Business Air Conditioning Units Be Serviced?

For most businesses, having your air conditioning serviced once every 12 months is usually sufficient. However, the more frequently your system is serviced, the lower the chance of unexpected breakdowns. If your air conditioning system is used for both cooling and heating, especially during the hotter months, servicing it twice or even three times a year is ideal.

Regular air conditioning maintenance helps identify issues you might not notice, such as dirty filters, worn electrical connections or blocked condenser coils. These small problems can make your system work much harder than necessary, increasing energy consumption and costs. A simple but effective tip is to note down the last time you cleaned or replaced your filter to keep your system running efficiently.

Clogged filters or indoor heat exchangers can cause the indoor fan coil unit to become noisy as it struggles to pull and push air through the system. Eventually, this lack of airflow can cause the fan motor to over-spin, leading to overheating and potential burnout of the motor and electrical components, resulting in costly repairs.

Blocked heat exchangers can also increase refrigerant gas pressure, which may cause the system to ice up, leading to water leaks. In severe cases, the refrigerant gas can turn into liquid and flood the outdoor compressor, resulting in catastrophic compressor failure and very high repair bills.

A well-maintained system doesn’t just cool or heat your space but it can also boost morale and output. Learn more in our guide on how commercial air conditioning improves employee productivity

Benefits of Servicing Commercial Air Conditioning Units More Frequently

Commercial air conditioning systems normally need at least one annual service and often more frequent attention depending on scale, type of system (split type / multi type / VRV or VRF type), complexity, running hours and the environment. Systems in industrial, retail or hospitality settings gather dirt quicker and run for longer periods, so wear builds up faster and more frequent air conditioning servicing pays off.

At Chillaire, we recommend routine visits every six months for many commercial installations. We also offer planned maintenance contracts to manage service schedules.

What Are the Signs That My Air Conditioning Unit Needs Servicing?

You don’t always notice problems with your air conditioning unit until they get serious. Watch out for:

Rising electricity bills even though your usage hasn’t changed
The system struggling to reach the thermostat setting on really hot days
The unit running almost non-stop or cycling on and off a lot
Unusual noises, burning smells or leaks due to clogged indoor heat exchangers or filters
Dirt or blockages on the outdoor heat exchanger condenser coil

If any of these happen, it’s a good idea to book an air conditioning service with an accredited surveyor. If your air conditioning is showing signs of age or frequent faults, our guide on when to replace your air conditioner can help you decide if it’s time for a new system.

Schedule a service with Chillaire if your unit shows any of these signs. Our engineers can catch problems early and save you money later.

How Can I Maintain My Air Conditioning Unit Between Servicing’s?

Maintaining your air conditioning unit or system between professional visits helps prolong its life.

Check filters every month during heavy use and replace them if they look dirty.
Keep the outdoor condenser clear of leaves and debris.
Don’t close vents in rooms you’re not using.
Set your thermostat earlier in the day to avoid lots of short on and off cycles.
Listen for unusual noises and watch for strong smells, which can be an early warning.

Regular air conditioning maintenance between servicing will help you spot any small issues early.

what are the different types of industrial heating systems infographic

What are the Different Types of Industrial Heating Systems

An industrial heating system is designed to generate and distribute heat efficiently across facilities such as factories, warehouses and commercial buildings. In this guide, we look at the main types of industrial heating systems, including warm air heating, radiant tube heating, heat pumps and destratification fans.

Types of Industrial Heating Systems

Warm Air Heating

Warm air heating systems distribute warm air through ductwork and vents in walls, floors or ceilings. Fuelled by gas or electric, they heat cool air through a heat exchanger, and that warm air circulates throughout the space.

Best for: Warm air heating effectively blows warm air throughout large spaces, making it a preferred industrial heating option for warehouses and distribution facilities.

Types of Industrial Warm Air Heating:

The following are common types of industrial warm air heating:

Suspended warm air heaters
- Suspended warm air heaters are fitted to ceilings or roof beams, allowing warm air to be evenly distributed across large open areas without taking up floor space.

Cabinet warm air heaters
- Cabinet warm air heaters are floor-standing units that deliver consistent heat, making them ideal for factories or workshops with limited ceiling height.

Benefits:

Heats large spaces quickly, keeping conditions comfortable for workers and equipment.
Energy efficient and low maintenance compared to traditional radiators.

If you’re looking to heat your warehouse or factory efficiently, you can learn more about warm air heating installations from Chillaire.

Radiant Tube Heating

Radiant tube heating uses gas-fired steel tubes mounted overhead, which release infrared heat that works much like sunlight. Instead of warming the air, the radiant tubes send heat directly to people, objects and surfaces below.

Best for: This type of industrial heating system is especially effective in high-ceiling environments such as workshops and sports facilities, where traditional air-based systems can lose heat quickly. They are also ideal for spaces where people remain in one spot for extended periods, such as valets and garages.

Benefits:

Radiant tubes reduce energy waste and heat loss compared to systems that try to heat up the entire volume of air.
Each radiant tube layout can be custom-designed for the building, meaning the heating is more targeted, and so it delivers better performance

Learn more about Chillaire’s radiant tube heating installations for reliable options for your workshop or garage.

Heat Pump Systems

Industrial heat pumps extract heat from the air or ground to deliver efficient, renewable heating. They work through a heat transfer process that captures ambient heat via an external heat pump unit. The system then increases the temperature of this heat and circulates it into the indoor environment. Using a combination of renewable energy and electricity, heat pumps provide a clean and cost-effective way to warm internal spaces.

Best for: These systems are suitable for a wide range of applications, from small and large offices to residential buildings. Larger setups, such as multi-office complexes, can use a VRF (Variable Refrigerant Flow) system, where multiple indoor fan coils connect to a single inverter-driven, energy-efficient heat pump.

Benefits:

Highly energy efficient
Operates using renewable energy sources, helping reduce carbon emissions.
Can provide both heating and cooling

Find out how our heat pump systems at Chillaire can help your business reduce energy bills.

Destratification Fans

Destratification fans are an effective industrial heating solution designed to improve energy efficiency by eliminating thermal stratification. Thermal stratification happens when warm air rises and cooler air settles near the floor, creating distinct temperature layers. This is a common issue in tall buildings such as warehouses or factories.

These large, powerful fans are installed in the ceiling to continuously circulate warm air from the top of the space back down to floor level. This blends it with cooler air to create an even temperature throughout the area.

Best for: Ideal for tall industrial or commercial spaces, such as warehouses, factories and distribution centres, where warm air tends to accumulate near the ceiling. They are particularly useful in winter when maintaining consistent warmth at ground level is essential for comfort and efficiency.

Benefits:

Prevents heat loss by redistributing trapped warm air from the ceiling to occupied areas.
Helps create a consistent, comfortable temperature throughout large open spaces.
Can be integrated with existing heating systems to enhance performance and sustainability.

How to Choose the Right Industrial Heating System for Your Facility

Selecting the most suitable industrial heating system depends on several key factors, including:

Building size and ceiling height
Level of insulation and air leakage
Frequency of use and operational hours
Fuel availability (gas, electric, renewable)
Environmental goals and running costs

Large open spaces (such as warehouses or distribution centres) often benefit from warm air or radiant tube heating systems, which can deliver even coverage across wide areas. Partitioned spaces or multi-level facilities may require zoned control systems or heat pumps for efficient temperature management.

In buildings with high ceilings, warm air naturally rises, leading to heat loss and uneven temperatures. Installing destratification fans helps recirculate trapped warm air from the ceiling back down to the working level.

how effcient are heat pumps for commercial businesses infographic

How Efficient are Heat Pumps for Commercial Businesses?

When well-maintained and functioning correctly, heat pumps in commercial buildings are highly efficient. However, the exact proficiency of a heat pump depends on the existing insulation in a building, the size and type of the heat pump itself, and the regularity of its upkeep. Each factor will inhibit the heat pump’s ability to work effectively, so it’s essential to consider every angle when choosing a system for installation.

How Do Heat Pumps in Commercial Buildings Work?

Commercial heat pumps use refrigeration cycles, similarly to an air conditioner. However, the function can also be reversed to warm a building as well as cool it.

The heat pump extracts thermal energy from the air, ground, or body of water.
A liquid refrigerant inside the pump converts the thermal energy into gas.
A compressor then increases the pressure of the gas, significantly raising its temperature.
Lastly, the heat is expelled into the indoor air or water-based heating system for circulation.

How is the Efficiency of Commercial Heat Pumps Measured?

The Coefficient of Performance (COP) measures the efficiency of a commercial heat pump. Because heat pumps work only by moving heat around, they have the potential to transfer more energy than they consume. Conversely, traditional heating systems generate heat, meaning they can only output the volume of energy equal to the input.

The calculation for the COP of a heat pump uses this simple formula:

COP = Heat Output (kW) ÷ Energy Input (kW)

A heat meter calculates the heat output, measuring the flow rate and water temperature difference when it enters and exits the system. Similarly, an electricity meter calculates the energy input.

What Factors Affect the COP of Heat Pumps in Commercial Buildings?

Temperature Difference

A commercial heat pump’s efficiency depends on the difference between the source temperature (eg, the outdoor air) and the temperature you are trying to get the room to. The colder a room is, the more intensely the heat pump must work to achieve your desired temperature, significantly lowering its COP.

The Type of System You Have Installed

Ground-source heat pumps generally have a higher COP due to the consistency of the ground temperature year-round. Air climates fluctuate significantly with seasonal changes, which heat pumps work overtime to counteract. So, ground-source heat pumps are usually more stable and constant than air-source alternatives.

The Regularity of the Heat Pump’s Maintenance

Commercial heat pumps require routine maintenance to sustain their COP (Coefficient of Performance). Any issue that restricts heat exchange forces the system to work harder. This results in higher electricity consumption to deliver the same output.

The most important maintenance tasks are cleaning the heat exchanger coils (indoor and outdoor) and filters. These are simple jobs but essential for keeping the heat pump running efficiently.

It is also important to check the on/off temperatures across the heat exchangers. This provides valuable information about the refrigerant charge. If the refrigerant level is incorrect, the system’s performance and energy efficiency will drop. As a result, the heat pump may use more energy and run for longer periods to achieve the desired output.

Other essential checks include the fans, motors, thermostats, and sensors. A thermostat or sensor that is out of calibration can cause the system to deliver incorrect readings. This leads to poor performance, higher energy usage and unnecessary strain on the heat pump.

Why do Commercial Heat Pump Coils and Filters Have to be Regularly Cleaned?

While in heating mode, the coil struggles to absorb heat from the air. And when in cooling mode, the coil can not release heat effectively. Similarly, the filters accumulate dirt, dust, and debris over time, causing an insulating barrier and interfering with the heat transfer rate.

How do Refrigerant Levels Affect the COP of a Commercial Heat Pump?

Heat pumps use a precise amount of refrigerant, which allows them to function optimally. Unidentified leaks can cause the system’s pressures and temperatures to fall out of the optimum range. Additionally, the compressor has to work harder to circulate the insufficient refrigerant levels, substantially reducing heat transfer capacity.

How Often Should the Components of a Commercial Heat Pump be Inspected and Calibrated?

You should have the components of a commercial heat pump inspected and calibrated biannually. However, depending on the demands of your operations, more frequent maintenance appointments might be necessary. You should employ a certified contractor once a year to recalibrate the thermostats, controls, coils, refrigerant levels, electrical connections, and moving parts. However, filters should be cleaned and replaced every 1-4 months, more regularly in high-traffic areas.

COP vs. SCOP for Commercial Heat Pumps

COP is the instantaneous measure of efficiency, and SCOP is a long-term efficiency measure over an entire heating season. For businesses, SCOP can measure the extended efficacy of a commercial heat pump system, accounting for a range of variables, including:

Fluctuating outdoor temperatures and how the commercial heat pump’s efficiency changes with seasonal shifts.
Partial load performance factors how efficiently the heat pump operates when it is not running at full capacity.
Defrost cycles to calculate the energy consumed in cold weather.

The calculation for the SCOP of a heat pump uses this simple formula:

SCOP = Total Energy Input During Season (kWh) ÷ Total Heat Output During Season (kWh)

SCOP provides a more reliable basis for comparing heat pump models and calculating your return on investment.

How Does Building Insulation Affect the Efficiency of Commercial Heat Pumps?

Well-placed building insulation minimises heat loss in the winter and keeps heat out in the summer, significantly benefiting the efficiency of your commercial heat pump. A poorly insulated building allows warmth to escape quickly, forcing the heat pump to run at higher speeds more frequently for the same heat output. Proper insulation could even allow you to purchase a smaller system with lower running costs, which may offer a higher return on investment long-term.

The key areas of your building’s envelope to focus insulation improvement on are:

Walls
Roof and Ceilings
Windows and Doors
Floors

How to Clean and Maintain HVAC Systems

Learning how to clean and maintain HVAC systems is one of the best ways to keep them safe, efficient and reliable all year round. So, what is HVAC maintenance? It’s the regular cleaning, inspection and servicing that ensures your equipment performs at its best while keeping energy costs under control. Without it, systems become less efficient, air quality suffers and unexpected breakdowns become more likely.

In this guide, we’ll explain why HVAC maintenance matters, what is done during HVAC maintenance, the simple steps you can take yourself and the benefits of using professional HVAC maintenance services. At Chillaire, we’ve been helping homes, businesses and industrial clients across the Midlands take care of their HVAC systems for more than 30 years, so you can trust that regular maintenance really does make a difference.

What Is HVAC Maintenance?

When we talk about HVAC maintenance, what we mean is the regular cleaning, inspection and servicing. This keeps your heating, ventilation and air conditioning systems working safely and efficiently.

HVAC stands for heating, ventilation and air conditioning. In simple terms, this system keeps you warm during winter and cool during summer, controlling the climate inside your building.

So, is it worth maintaining? Absolutely. Without proper care, these systems can affect your comfort, energy bills and even your health. Poorly maintained equipment can lower air quality, making it harder to breathe. Regular HVAC maintenance helps you avoid breakdowns and keeps the environment inside your premises healthy.

Is HVAC Maintenance Important?

There are plenty of benefits that come with keeping up a HVAC maintenance routine:

Safety
HVAC systems often run on electricity or gas. Having them checked each year is essential. Technicians look for electrical faults, gas leaks and carbon monoxide levels. Safety really is the top priority.

Indoor air quality
If the system is dirty, the air you breathe is dirty. Dust, mould and allergens can build up inside your ducts and filters. Maintenance makes sure your system is circulating clean air.

Lifespan
Equipment that’s blocked with dirt or never inspected will wear out faster. Regular maintenance extends the life of your system, protecting your investment.

Energy efficiency
A dirty system has to work harder, which means it runs longer and uses more power. Keeping everything clean and tuned reduces your energy bills.

Peace of mind
When all these points are covered, you can relax knowing your HVAC system is reliable, safe and ready for the season ahead.

DIY vs Professional HVAC Maintenance

Annual HVAC maintenance is an investment worth making. A system that is serviced properly not only uses less energy but also provides better comfort at lower costs.

Working with professional HVAC maintenance services is important because trained technicians can spot problems early and carry out repairs to keep everything running smoothly. Homeowners or business owners simply don’t have access to the specialist knowledge and tools required for a thorough service.

Professional HVAC Maintenance Services:

A typical annual HVAC service carried out by a professional technician should include:

A full clean of the furnace or air conditioning unit
Inspection of safety switches and devices
Checking for cracks or damage in the heat exchanger
Filter replacement
Calibration of temperature and airflow controls
Washing of the outdoor condenser coil
Adjustment of fans and belts
Inspection of drains and traps
Testing of all electrical components

This level of care ensures the system runs as efficiently as possible and reduces the chance of breakdowns at the worst time of year.

How can I Keep my HVAC System in Good Condition

There are a few simple maintenance tasks that are safe and effective for homeowners and business operators:

Keep filters clean. Replace or wash them regularly to stop blockages and keep air moving freely.
Keep vents open. Avoid placing furniture or curtains in front of them so the air can circulate.
Clear around the outdoor unit. Remove leaves, rubbish or overgrown plants so airflow isn’t blocked.
Cover smartly in winter. If icicles form above your unit, protect it with a piece of plywood placed on top. Otherwise, leave it uncovered so moisture isn’t trapped inside.

These steps will help extend the life of your HVAC system, improve efficiency and make professional servicing even more effective.

How Long Does Air Conditioning installation take red and blue infographic

How Long Does Air Conditioning Installation Take?

If you’re planning a new AC installation, one of the first things you’ll want to know is how long it takes to get your system up and running. The answer depends on the type of system and whether you’re installing air conditioning in a single room or setting up a large commercial HVAC system.

For most homes, you can install an air con in as little as 4 to 8 hours for a standard split unit, while multi-split or ducted systems can take several days. On the other hand, commercial projects are often larger and more complex, meaning installation can take anywhere from a single day to a full week or more.

In this guide, we’ll break down the typical timeframes for installing air conditioning, from quick window units to full whole-house and commercial HVAC systems.

How Long Does it Take to Install Air Conditioning?

When thinking about installing air conditioning, one of the first questions is how long the process will take. A typical air conditioner installation can take anywhere from four to eight hours to complete. In some instances, this can take longer depending on the scope of the project.

However, a full HVAC installation will definitely take longer. A simple residential system may take 1 to 5 days, while a larger commercial or industrial installation can take several weeks. Knowing the typical install time helps you plan your schedule and prepare your home or business for the work ahead.

How Long Does it Take to Install Standard Home AC Units?

For a single, standard air conditioning unit, such as a wall-mounted split system, the installation typically takes between 4 and 8 hours. This usually means the job can be done in one day, so if installation starts in the morning, you could be enjoying cool air by the evening.

In some instances, particularly for very straightforward setups, the process might even be finished in as little as 2 to 3 hours. Window units are the quickest installation option, often requiring just 30 minutes to fit. A simple wall-mounted unit is inherently much quicker to install compared to a concealed ducted system, which necessitates more extensive structural work.

How Long Do Multi-Split Systems & Central Air Conditioning Take to Install?

Multi-split air con systems are used when a property requires cooling in more than one room. These systems typically involve one outdoor unit connected to several indoor units, commonly between two and four. The installation of such a system generally takes around 6 to 8 hours. However, for multi-split systems designed to cover two to four rooms, the duration can extend to

1 to 2 days. If the system is intended for three or more rooms, the installation period may increase to 2 to 3 days. Central air conditioning installations, which often involve a more integrated approach, can take up to 8 hours to complete.

How Long Does it Take to Install Whole-House Ducted Systems (HVAC)?

A comprehensive HVAC (heating, ventilation and air conditioning) system, designed to cool an entire home through a network of ducts, is a more extensive installation project. Such a complete system typically requires 3 to 5 days for installation. Should the project necessitate significant structural modifications to accommodate the ductwork or units, the timeline could extend to a full week.

It is worth noting that replacing an old HVAC system can often be quicker than installing a brand-new one, as existing ductwork may already be in place.

How Long Does It Take to Replace an AC Compressor?

While often considered a repair rather than a full installation, replacing an air conditioner compressor is a critical task that directly impacts the unit’s functionality. This process typically takes approximately 2 to 4 hours. The compressor is the core component responsible for circulating the refrigerant, which is essential for generating cold air.

Typical Home Air Con Installation Timeframes

Air Con System Type	Estimated Installation Time
Window Unit	30 minutes
Standard Split Unit (Single Room)	4-8 hours
Multi-Split System (2-4 Rooms)	1-2 days
Multi-Split System (3+ Rooms)	2-3 days
Central Air Conditioning	Up to 8 hours
Whole-House Ducted System (HVAC)	3-5 days
AC Compressor Replacement	2-4 hours

How Long Does Commercial Air Conditioning Installation Take?

Commercial air conditioning systems are very different from home units. They are designed to meet the demands of large spaces such as offices, retail stores, factories and hospitals. Installing air conditioning in a commercial environment comes with unique challenges. The scale, complexity and operational needs of a business often mean that new AC installation takes longer than a typical home air con installation.

While installing air conditioning in a home might be done in a single day, commercial projects can take anywhere from one day to a full week or even longer. This is entirely dependent on the system type and the building’s characteristics. Here’s what influences the timeline:

Building Size

The size of the commercial property is a major factor. Larger buildings need more extensive HVAC systems, often with multiple units, which naturally increases installation time. For comparison, when you install AC in a house, you’re usually working with a single, smaller system, which is much quicker than outfitting an entire office or warehouse.

Type of Installation & System Changeout

The nature of the project makes a big difference:

Simple changeout: If you’re replacing an old unit with a similar one and the existing infrastructure such as ductwork, wiring and controls, is still usable, the team can often install air con in as little as one day.
Full system replacement: A more complex project, involving new ductwork, thermostat rewiring or complete system redesign, can take three to five days or more.

Location of the HVAC Unit

Where the system will be installed matters. If the HVAC unit needs to go on a roof, especially a high or hard-to-access one, the process is more complex. Cranes or lifting equipment may be needed, which adds both time and cost. It can also require additional technicians to ensure everything is done safely.

Workspace Needs

Every business has unique requirements. Office layouts, occupancy levels and the presence of heat-generating equipment like server rooms all affect system design. Detailed heat load calculations and proper system sizing are essential and these extra planning steps can influence how long the installation takes.

Although the majority of air conditioning systems work in the same way, there’s a big difference between what’s needed for homes and commercial spaces.

Commercial AC is designed to meet the unique demands of businesses, making them larger, more powerful and more complex than home units. Whereas, home HVAC systems focus on comfort and efficiency for smaller residential areas.

In this article, we’ll share with you the key distinctions between commercial HVAC systems and home HVAC systems. From differences in design and performance to maintenance and functionality, understanding these differences can help you choose the right solution for your space.

What is Commercial AC?

Commercial AC is also referred to as commercial HVAC (Heating, Ventilation, Air Conditioning). The word commercial means that the AC units are specifically designed to meet the demands of large spaces such as offices, retail stores, factories and hospitals.

Unlike home HVAC systems, which cater to smaller private spaces, commercial HVAC systems are built to cool large areas with multiple rooms. In some cases these units cool entire buildings and run for extended hours to accommodate business hours.

Types of Commercial HVAC Systems

Since commercial air conditioning systems are designed to meet different needs than home HVAC systems, the units are different. Below are the some of the various types of commercial HVAC units:

VRF Systems

A Variable Refrigerant Flow (VRF) system is a complex HVAC system, designed to provide temperature control to multiple rooms and units at the same time. You’re able to add more AC units to the same VRF system at any time, making them a versatile choice for commercial businesses.

VRF systems use a single outdoor unit connected to multiple indoor units, with refrigerant flow adjusted based on each room’s heating or cooling needs. This allows individual rooms to maintain different temperatures simultaneously.

Multi-Split Systems

Multi-Split HVAC systems consist of a single outdoor unit connecting to multiple indoor units. While this may sound identical to a VRF system, they differ in their capacity and functionality.

Multi-split systems can only distribute a fixed amount of refrigerant to each indoor unit. This offers basic room temperature control but with limited efficiency compared to VRF systems. They are best suited for medium sized commercial spaces and they’re more affordable and simpler to install.

Ceiling Cassettes

A ceiling cassette unit is a type of indoor air conditioning unit that is installed in the ceiling. It’s a discreet and space-saving solution for cooling or heating a room. Ceiling cassette units typically cannot operate on their own without being part of a larger commercial HVAC system.

It is designed to work hand-in-hand with outdoor units, such as in a mini-split or VRF system, which provides the necessary refrigerant and power for the ceiling cassette to function.

So how is Commercial AC Different From Home AC?

While both commercial AC and home AC systems serve the same purpose of cooling indoor spaces they still have many key differences:

Different Size and Capacity: Home HVAC systems are much smaller and less complex compared to commercial AC. Home systems are designed to cool individual rooms or small houses.
Different Installation Requirements: Commercial HVAC systems are much more complex and large-scale. This means the installation process requires more time and precision compared to home HVAC.
Cost: Due to their larger scale and complexity, commercial air conditioning systems are more expensive to install, operate and maintain.
Usage: Commercial AC is designed for continuous operation. Whereas home HVAC units are used for shorter periods, often just during hot weather or at specific times of day.

Gas Radiant Tube Heater Installations

Gas radiant heating is a completely different way of providing heating to a designated area or half open buildings compared with gas warm air heating.

The radiant tube heater operation ensures a cleaner-burning, ultra-efficient heat. They can be ideal for part heating a building or designated spaces inside a large building or hard-to-heat large buildings looking for an environmentally low carbon footprint heating solution like warehouses and workshops.

The burner in a gas radiant tube heater generates a long laminar flame inside the radiant tube. This flame heats the radiant tubes up to around temperatures of 550°C to 580°C. An exhaust system mounted at the end of the tube heater discharges the combustion exhaust gas to atmosphere.

Therefore, the limitation of these types of heaters can be to their advantage, the heat can be directed more precisely as long as somebody or something is in reach of the heating appliance. They are suited for production areas or parts of a warehouse or car garage workshops where people work only in a part of the building or are constantly moving around.

Winter-warm

The WRU and WRL series are eminently suitable for use in combination with indirect-fired air heating.
A relatively small air-heating capacity can keep the room at a certain minimum temperature while the workplaces themselves can be pleasantly boosted by a radiant tube.
The radiant tube can be switched on as and when required, and the comfortable heat is felt almost immediately.

In situations where an old, poorly insulated factory bay has to be heated, the heating of the entire bay with radiant tubes provides an excellent heating solution. Effective and energy saving.
The effect of radiant heat is felt immediately, and it ensures a long period of retained heat so the radiant tubes can be switched off well before the end of the working day. Transmission losses are relatively low as surfaces are heated instead of the air which escapes through the roof, bad insulated walls or other cracks.
