Powrmatic Heaters

Powrmatic is one of the UK’s best-known manufacturers of commercial and industrial space heating, offering everything from warm air unit heaters to radiant tube heating systems designed specifically for large buildings.

Powrmatic Heaters Explained: What They Are, How They Work & Whether They’re Right for Your Building

If you run a workshop, warehouse, factory, garage, sports hall, school, or commercial unit, heating the space efficiently can be a real challenge — especially when ceilings are high and doors are constantly opening.

What is a Powrmatic heater?

A Powrmatic heater is a commercial heating system built to heat large spaces quickly, safely and efficiently.

Unlike a home boiler system (radiators), Powrmatic units are usually designed to either:

✅ blow heated air into the building (warm air heating)
or
✅ heat people and surfaces directly (radiant heating)

Their product range covers multiple types of industrial heating systems, including warm air cabinet heaters and radiant tube heaters.

What types of Powrmatic heaters are there?

1) Warm Air Unit Heaters (the most common)

Warm air heaters work by heating air and distributing it into the space (either directly, or via ductwork).

These are often ceiling suspended or mounted at high level, making them ideal for open industrial spaces.

A popular example is the Powrmatic LX range of suspended warm air unit heaters, designed to deliver rapid and even heat distribution.

Best suited for:

• workshops

• warehouses

• light industrial units

• garages

• sports buildings

2) Warm Air Cabinet Heaters (bigger output, more options)

Cabinet heaters are larger units with higher outputs, suitable for bigger buildings or where ductwork is required.

Powrmatic’s CX range is designed for flexibility (horizontal/vertical installation, ducted, plant room etc.) and includes modern modulating burner technology aimed at reducing NOx emissions.

Best suited for:

• factories

• logistics buildings

• large warehouses

• retail sheds

• buildings requiring ducted warm air

3) Radiant Tube Heaters (great when doors are open)

Radiant heaters don’t heat all the air in the building — instead they warm people, products and surfaces (similar to the warmth you feel from the sun).

Powrmatic’s SRP radiant heaters are commonly available in U-tube and linear formats, with outputs typically around 10–60kW, and are ideal where there’s high air movement.

This is one of the best options if:

• doors are frequently open

• the building is draughty

• you need “targeted heat” over work areas

Best suited for:

• loading bays

• workshops with open shutter doors

• garages and MOT bays

• manufacturing zones

What fuel do Powrmatic heaters use?

Depending on the model, Powrmatic heaters can run on:

• Natural Gas

• LPG (Propane)

• Oil (for sites without gas supply)

• Some ranges are also available in electric / hot water / steam formats depending on application

For Dorset and surrounding areas, gas and LPG are common on industrial estates — while oil-fired warm air heaters can be ideal for rural commercial buildings.

Why choose a Powrmatic heater?

✅ Fast heat-up time

Warm air systems heat large spaces quickly — ideal for buildings that aren’t in constant use, such as workshops and garages.

✅ Efficient for big open buildings

Radiators can struggle in large-volume spaces. Powrmatic systems are designed specifically for this type of environment.

✅ Flexible installation options

Many systems can be installed:

• suspended

• wall-mounted

• cabinet style

• ducted

• plant-room installed

✅ Better comfort in hard-to-heat spaces

Radiant systems are particularly good for comfort where warm air would simply disappear into the roof space.

Common questions we get asked

“Why is it warm at the roof but cold below?”

This is classic heat stratification — warm air rises and sits at high level.

A Powrmatic warm air system can be improved massively by adding:

• proper heater positioning

• ducting or directional discharge

• destratification fans (in some buildings)

“Is radiant heating better than warm air?”

Neither is “better” — it depends on the building.

Go warm air if:

• you want whole-building heat

• you have a decent envelope (less draughty)

• the building is used consistently

Go radiant if:

• doors are open often

• the building is draughty

• you only need to heat certain zones

Installation and servicing considerations

Powrmatic heaters are robust commercial units — but like all combustion appliances they need:

• the correct flue setup

• correct ventilation

• safe commissioning

• regular servicing

Some models can be installed room sealed or flued-only depending on the design, and installation should always follow manufacturer requirements and relevant UK safety standards.

How often should a Powrmatic heater be serviced?

In commercial environments we usually recommend:
✅ at least once per year
(or more often in dusty/high-use environments)

A service typically includes:

• burner checks and combustion testing

• heat exchanger inspection

• safety checks

• fan and airflow checks

• controls and thermostat verification

• flue integrity inspection
