Space Heaters

When freezing temperatures threaten to halt your project, you need reliable, high-output climate control. At Electro South West Ltd, our range of professional gas-fired space heaters provides the instant, high-volume heat required to warm large industrial spaces, agricultural buildings, and well-ventilated construction sites.

Whether you are accelerating the drying process of plaster and concrete or simply ensuring your team remains warm and productive during long winter shifts, our collection delivers uncompromising performance. Powered by highly efficient propane or butane, these forced-air heaters feature robust steel casings, variable heat outputs, and essential built-in safety mechanisms such as thermal overload protection and automatic flame-failure devices.

Because these are direct-fired heaters, they must always be used in well-ventilated areas to ensure safe air quality. To get your heating system up and running, pair your unit with our heavy-duty Site Power & Extension Leads to power the internal fan and ignition systems. Defeat the cold and keep your commercial project on schedule.

Frequently Asked Questions

Are direct gas-fired space heaters safe to use indoors?

Direct gas-fired heaters are highly efficient, but because they release the by-products of combustion (including moisture and carbon monoxide) directly into the heated space, they must only be used in highly ventilated areas. They are ideal for open construction sites, large warehouses with open bay doors, and agricultural sheds, but should never be used in tightly sealed, unventilated domestic rooms.

Do I need an electrical supply to run a gas heater?

Yes. While the actual heat is generated by burning the propane or butane gas, these heaters require a standard 110V or 230V electrical supply to power the internal fan (which forces the hot air out into the room) and the electronic ignition system.

What size heater do I need for my workshop or site?

Heater power is measured in kilowatts (kW) or British Thermal Units (BTU). The size you need depends on the total cubic volume of the space, the current ambient temperature, and the level of insulation. As a general rule for uninsulated industrial spaces, you will need a significantly higher kW output to maintain a comfortable working temperature than you would for an insulated domestic garage.
