overhead radiant or fa

[johnnyf]

Okay help me decide. I built a small 400 square foot room inside a pole building to house my machine tools (getting tired of condensation problems) r13 walls R19 ceiling and no insulation under concrete as is the entire pole building. Is overhead radiant a better way to go vs forced air ? will the radiant heat the concrete better. I was looking at a 7500watt forced air unit from chromalox should be good size but then I learned about radiant and do not know what to do. Also the room is sealed good caulked foamed etc.


Thanks John

Think of radiant like you'd think of the sun... nice and warm. I have a gas-fired radiant tube heater and it's really nice heat... ends condensation problems and warms the floor pretty nicely.

You can get a small radiant heater to use in that 400 sq.ft. and it will work good for you.

Thanks, I will pickup a small one and see how it does before doing final wiring just in case

The way I understand it, if its not electric it will need to be vented to the outside to avoid the condensation. I e-mailed a the company about a propane radiant heater. One of those square ones that are more for spot heating. There reply was that to have proper ventalation to avoid condensation I would need 24 square inches of opening to the outside. In other words leave a window open.
