How much heat will I need?

[87 GN]

My garage is 19' x 24' with an 8' high ceiling. Any idea what I will need in BTU's for that space?

Leaning twords an electric ceiling mount unit or units, any recomendations?

Trying to get around not having an open flame.

Thanks,

Any better options for me?

try this out.. how cold do you think your garage will get, say 30 degree, and how warm do you want it.. maybe 50, maybe 80

Will determine the BTU size you need

If you want electric, this is one I have installed and it's easy to mount on the ceiling, you can use a jumper to set the desired KW to tune down the BTU if it is too much. (5/4.1/3.3/2.5 KW) It can make the meter spin pretty good though so if you are in the garage like 8 hours a day 5 days a week I would go with gas.

Obviously you didn't get it. You did not give us any info to base advice on. insulation? windows? drafty? new? old? location? intended use?

Sorry.

Its an old detatched garage 19'x24' with an 8' ceiling. It is block, with a wood frame roof. I will be building walls out on the interior and insulating with R13 in 2x3 studs. Outside of the block will be furred out and insulated with 1" foam
then vinal sided. I will install 1/2" drywall over interior studs and in the ceiling. Ceiling will be insullated as well. I will be changing the front of the garage to a single insulated 10' or 12' door with a 32" regular man door to the right of the larger garage door so I do not let my heat all out the large door in the winter.

I have 2 window which will be changed out with new windows, also have 2 window ac units I will use in the summer to cool the garage when working in there. They will be removed in the winter.

I will be working in the garage on weekends and maybe a few nights after work, not all day every day.

Here is a picture of the exterior now, hope to start work on the garage in July/August after I vinal side the house.

I would think for your uses, a small gas heater would be all you need. It isn't that big of a space. You could go electric, but I think it would be pricey to run.

Consider foam rather than stud wall and fiberglass. While fiberglass is the cheapest per r value, if you used plywood rather than sheetrock, you could screw right to it to hang things etc. . At any rate, the net cost might be similar, especially considering labor.

Heat rises, insulate the ceiling well

I'll be doing all the work myself so however I do it there will not be any labor rates

I contacted my old boss he is an estimater for an hvac comany he can get me this unit http://www.schwankgroup.com/en/prod-lum-supra.asp which is something like 96% efficant and runs on propane. He is working a price up for me, and trying to get the spec sheet for me to.

Figuring on R39 for the ceiling.

Hey, since your labor is free, got any spare time....
Seriously, while it might mot be 100 bucks an hour,k it is still valuable, plus you can lose less space with foam

Spare time, yea right

All my free time has been spent working on my house, purchased it in april of 2006 gutted it and remodeled everything, just moved in this Jan. Took forever because I did al the work myself but I saved allot doing it all myself. I am now working on the outside to get ready for the siding to be installed, working in the garage to get that into a nice working area so I can pull the chassis out from under my car this winter and after the garage is done I will have my own space to hang out. Havent had a vacation in 3 years and this wedding **** is taking up time also, getting married in Sept. Might have some spare time this time in 2009

a quick heat load based on Philadelphia is about 21,000 BTUH, this includes a little bit extra for infiltration. as far as electric heating goes it's approx 6.1 KW per hour.

This does not allow for much large door opening time
