Unit Heaters

Modern unit heaters are more energy efficient than in the past. Electronic ignition has replaced wasteful pilot lights, which adds up to big savings on heating bills.

We install custom gas-fired unit heaters, ranging in size from as small as 30 thousand BTU’s to units of up to one million BTU’s. We also install power-vented, high-efficiency inline duct heaters, and ducted units.

Unit Heaters for Heating Large Spaces

Unit heaters are ideal for heating large spaces such as warehouses, workshops, large garages, or other spaces with high ceilings. However, they are also appropriate for installation in offices or meeting halls, for example.

Space Saving

Units don’t require large ducting systems that take up valuable space, and they can be mounted in a variety of ways to make the best use of space and maximize comfort. Our smaller units are very compact in design, taking up very little room while still emitting a lot of heat for their size.

Unit Heaters: Durable, Low Cost, Easy to Maintain

The ruggedness and durability of the heating units makes them ideal for industrial applications. They can be installed at a lower cost than other heating systems and require less maintenance than furnaces or commercial rooftop units as there are no filters to replace.
