I have an insulated garage that I want to heat, but just above

Does anyone know of such a heater? I can't seem to find one.
Thanks!




I live in Canada where it would be usual to have this application. The
garage that I want to heat to just above freezing is attached to the
house, well insulated so a heater with a thermostat that can be set from
about 0 degrees C to 10 degrees C or more would fit the bill. My question
is - why do manufacturers not provide this option, and why can I not find
ANY heater that gives the minimum and maximum temperature setting of the
thermostat on the box?


I have a ceiling mounted electric heater with fan. Not sure of the
exact thermostat range as it's unmarked except for little dots and an
off position. I keep at "just on" over the winter and it keeps my
insulated shop at about 40 degrees. When I want to spend time out there
working, I just pop in, turn it up a bit and within 15 minutes or less I
can work in my shirtsleeves. At a rate of ~ $0.1035 per kWh the affect
on my monthly electric bill is negligible.

If you can't find one looking through Grainger, et al, let me know and
I'll pull the model number and make for you.

Alternatively, I suspect that it might not be all that difficult to find
a line voltage thermostat that would operate in the range you want/need.
Just wire it into the circuit and leave the thermostat on the heater
set to your preferred "working temperature". Crank up the external line
voltage stat when you want to work out there, turn it back down when you
just want to keep it from freezing.
