Building A Garage

[Forzfed]

Not sure what the bylaw is for height.

Here the garage cannot exceed the height of the house.  If you have a 2 story your good to go!  And the rest of the stuff Rich said.

I have a 30x40 pole building. Metal liner panels on walls and ceiling, fiberglass 6" blankets in the walls, blown in cellulose in the ceiling.


I heat it with a two stage 30-40k, (I think) gas, radiant tube heater hung from the center of the ceiling. My ceiling is only 10', which isn't ideal for RT heaters, but the one I bought is designed for low ceilings and works VERY good.


I set it at 65 (unless my daughter is doing a project, then 68) and it stays dead on through the coldest nights here in NJ. Everything in the shop is at a comfortable temperature, including the floor.  T-shirt weather all year round.


After radiant floor, like GRumpy mentioned, radiant tube is the next best thing.


Oh, and its super efficient and I ran my own gas line, very easy to do.

Thanks Bullnerd...loo ks like the way I'll go. My son in law has his own small construction company and is looking after the complete build for me. I'll show him this. Thanks so much.

Also, I ordered the heater from a place called, Matchless-energy Management, In Parsippany NJ.  They are the distributor in my area for Superior radiant tube heaters. 

Guys name is John Grant, super nice guy and very helpful. He did a free heat loss calc and advised what size/type of heater to buy. 

Here is the official number of the one I have, Superior Radiant SeriesLTA04N3A Low Clearance Two Stage Heater 

No affiliation with these guys, just trying to help.

Thanks dude.

If I could have designed my shop, some type of heating coming from the floor.  Concrete is cold and sucks the life out of you

One of the places I worked removed the steam heat and replaced it with radiant.  The problem with radiant is you have to be standing right under it to be warm and when it was -20C or colder there was no heat.  But this was in a building with 40ft ceiling.  We referred to the radiant heat area as cold storage!

[bullnerd]

I've heard that before, but if it's set up properly, I dont think thats the case.


I can feel the difference from directly underneath my heater vs being over by the wall, but the difference is not really worth noting. If the room is insulated properly, it's hard to beat.


If you research how it works, It heats the stuff, the stuff radiates heat. The trick is to leave it on continuous, so all the stuff stays warm.


Floor stays plenty warm to touch/sit on when it's below zero outside.


The only other thing I would say to the op is do the best you can afford on the insulation, especially the ceiling.

I know exactly how radiant heat works.  And once it got colder than -30 the radiant heat was none existent because of the density of the air and the fact that heat rises!

[bullnerd]

Yeah, I wasn't implying anything.  

[Steve Wood]

Yeah, I wasn't implying anything.  

 LOL, hey, we learned that Brad must be building a shop 40 ft tall and that heat rises as compared to cold.  He should have been more specific and stated that radiant heat works, it just not work if one is 40 ft below it unless it has an assist fan.

Meanwhile, back in the real world...LOL

[reality]

Then we can argue if it's better to blow the cold air out or blow the hot air down or both:045:

[Steve Wood]

Lol. Excellent point!

[Forzfed]

Yeah, I wasn't implying anything. 

I'm just basically letting him know the pro's and con's.  For the last 5 years I have been working with heating controls and have seen lots of stuff.  One place I worked had a Geothermal, which was 100% useless in the winter.  If the inside is set for 22'C and the outside temperature is -45'C that is a delta T of 67 degrees, that was impossible for the system to work.  The Director even commented that we have the most expensive AC!  And even that I commented on why we are going through heat pumps when the ground water is exactly what the chilled water loop runs at.
Radiant heat would be good as long as your not opening the overhead door often and you're not dealing with extreme cold and wind.
