Venting your attic is for moisture control too. Yes it can reduce the temp in the attic but in a climate with both a heating and cooling season you need to remove the moisture in the attic to prevent mold and roof sheating failure. Power vents not only cost money to run but have a short service...

Check out this site www.geocomfort.com. It works great in my house.

Kevin54, What about insurance for the garage with a wood burner? Jumpin

Can't say your wrong about the cost of electricity going up in the future, but ask your self, when was the last time your power co. raised rates. Your gas co. raises the rates every winter when you need the energy. Most power companies have to apply for rate increases through some state...

No, you still pay the power co. Just a lot less.:thumbup: Jumpin

Using Pete's cost of electricity, it would only cost $11.43 to produce 1,000,000 btus of heat. Jumpin

One more thing, if you use an air-to-air heat pump you double the efficiency and cut the cost in half, $14.65. The other benefit...you added a/c to the mix because the heat pump both heats and cools. Jumpin

You guys are on the right track, but lets look at it this way. Let's say you needed 1,000,000 btus to heat your garage for the winter. If you get 91,000 btus from propane but it's only 70% efficient you need to multiply 91000X.70=63,700 btus. So, 1,000,000 / 63,700 = 15.7 gals of proane @ $1.60...

Poor design...you need to return as much air to the system as you deliver. A diffuser above each door is a bandade approch. Proper duct design is key to a comfortable house. I'm sure the upstairs will never be comfortable. One thermostat can't satisfy both floors. It may work, but that doesn't...

Deon, That's correct the amount of BTu's per sq. ft. will give you the size of the heating plant. Remember that's the amount of BTu's per hour needed to maintain the required temp. If I would have sized the tubing I would have firgured 9" spacing, to be on the safe side. The total sq. ft. of...

DLausche, On radiant floor applications you need to figure BTu's per Sq. Ft. To keep it at 50 to 60 degrees figure 15-20 BTu's per Sq Ft. 60 to 70 degrees figure 25-30. If the tube spacing is 12" centers with 1/2" tubing the max Btu's will be around 25. Soooooo... total Sq. Ft X BTu reguired...

Is that a 71 corvette or a storage shelf? Just kidding.:)

Chaz, I think you should also ask what kind of heat people have in the garage. Gas, or electric. Is it fourced air? With or without a duct system. Does anyone have infloor heat? When you talk about insulation what about the concrete slab. Edge insulation makes a big difference in the floor temp...

I'm a new garage journal junkie from Illinois... Hello everyone.
