I've sold my washes, but my largest equipment room was about 20 X 35. It worked great. I don't remember which BTU I picked, but 30K was more than enough. I think it may have actually been a 20K. If Dakota Hoskins sees this, maybe he can chime in on the size.I.B. I was thinking about the same thing. How many do you use and what’s the size of your equipment room?
We have the same unit, made by DaytonWe have an overhead natural gas fired radiant heater that is controlled by a wall mounted millivolt thermostat that requires no electricity. (technically it does but it produces its own from magic) As long as we have natural gas service then we have heat.
I have a patio heater at one wash. They work great!!Patio heater, because some of us in Texas losr power, water, AND gas.
