Unit Heaters
- Wide range of sizes and output ranges allow you to provide as much or as little heat as you need, where you need it
- Vertical throw unit heaters have fin and cone attachment options that help you customize heat distribution for your application
- Easily controlled by a thermostat and usually the only moving part is the fan motor
Unit Heaters use air forced through a steam or water heat exchanger (coil) to heat a space, coming in horizontal throw or vertical throw versions in a large variety of sizes. They are often used in larger spaces including warehouses, gyms, garages, or showrooms and mounted from the ceiling.

Do you have questions about Unit Heaters?
I have been using my unit heater with steam and am switching my system to hot water, can I use the same unit heater with the changed system?
Often yes, as many steam unit heaters are hot water compatible, though some changes will be necessary especially on the outlet side. Feel free to ask us about your specific application.
How are unit heaters usually mounted?
Typically, unit heaters are installed from the ceiling using the mounting holes built into the units.
Does a change in steam pressure affect the heat output of my unit heater?
Absolutely. There is a direct relationship between pressure and temperature of saturated steam so the lower the pressure, the lower the amount of heat available to transfer into the air with the coil.
