What is gas fired warm air heaters?

The most popular type of commercial warm air heaters in the UK are gas fired warm air heating systems, which warm the cold air over a gas flame, before forcing the air around the building. A gas warm air heating system can be floor standing, suspended from the ceiling or mounted onto a wall, and sometimes mobile.

What is the difference between direct and indirect warm air heating?

Warm air heaters contain a gas fired or oil fired burner that is used to heat a space either directly, or indirectly using a heat exchanger. When you’re making a decision about your industrial heating, it’s also worth deciding which will work best for your space, as every building is different.

Direct fired heaters are usually used for large empty spaces like construction sites and factories, and are not recommended for spaces where people are around. They are not the most practical, as they always need ventilation to the outside environment.

Indirect fired heaters are widely recognised as the more practical and versatile choice. They are ideal for places without ventilation and where people are present, because they provide lots of clean air safely and efficiently, and are better around combustible materials.

What is the difference between warm air cabinet heaters and suspended units?

Whether gas fired or oil fired, there are also different types of heating units that make them very versatile and suitable for different purposes and spaces – known as suspended heating units, and warm air cabinet heaters (sometimes known as cabinet space heaters, gas fired cabinet heaters, or industrial cabinet heaters).

Suspended units are attached to the roof or brackets on the wall, meaning they take up little space. They are equipped with louvres to help push the warm air down to ground level and distribute it around the building. For buildings such as schools or offices, they are a good option as they do not take up precious floor space.

Warm air cabinet heaters are larger, floor standing units that are installed on the ground. They usually come with nozzles or ducts to direct the warm air around the building. Therefore they can heat more than one area or room, because the nozzles or warm air ducts can move the air around wherever it’s needed. These are more useful for factories or large warehouses, where space isn’t an issue but different areas need to be heated. Because they are on the ground, cabinet heating units are also easier and cheaper to service, plus easier to fix if there are any issues.
