I don't think this is a very accurate post. You say hot air rises above cold air, but also say heat doesn't raise (sic). That's tivial semantics, and the difference doesn't matter . Your comment about square footage of walls and ceiling is not true. Almost all rooms/enclosed spaces have...

Vapor Barrier If you don't have any moisture generation in the garage you don't need a vapor barrier. A house has bathrooms and kitchens with water, and any combustion appliances generate moisture. Buy whatever you can get that's cheapest (foil faced, craft faced, or unfaced), but don't go by...

No Monthly Cost Estimate Yet I'm going to have to sit down and compare my few months of operation with historical bills to build an estimate. I suspect that will be of interest to folks, so I'll try to do it soon. I fired it up in January last year, and I think I shut it down in April. My...

Performance in Coldest Weather in 20 Years Just a note on how this system (described in first post) fared during temps that were really cold for Northern VA, down to 1.8* Tuesday morning. This winter I've set the week temp at 55 and the weekend temp at 60. I've left the lower element on 3800...

No way in metro DC Re: 24 x 26 Garage - $25000 a good deal? You couldn't touch that building for 25K in Arlington VA, which is probably not a comparison for you. You also can't put two 10' wide doors in a 24' wall and build to code for wind bracing. Two 9s is doable, and for today's wide...

Garden hose supply, drain ?? I have a garden hose feeding half a kitchen stainess sink in my wife's potting shed, as you're planning. My drain just dumps on the gravel under the shed, so no vapor barrier for me! No weed block either, they don't grow well in the dark. Sounds good - you doing...

Chop saw table, no need for pocket screws "BTW, not just Jeff, but anyone with knowledge.. please chime in on pros and cons of using Kreg jig versus 2x4 basics." He didn't NEED to build the miter saw stand with pocket screws, he just chose to. You could screw up through those flat 2x4s easily...

Have one, also. Thoughts on gable headers. I have a 2006 modular, built in PA and erected on Cape Cod. 2x6 construction, as I think most of them are, packed with insulation, built with dry materials in controlled conditions, can't get much better construction. The variables are who does the...

That one is priced WAAAY too high. I'll take forever to clean up, who knows what the accessory internals look like. I have a 1956 which used to be my uncle's who built many a fine piece on it. I currently use it only as a drill press because I've collected individual tools to do the rest. It...

Walleye Catcher said he'd done 30-40 systems like this, and had plenty of information for you. I put in a link to my post about my system which uses a 30gal tank with a convertible 3800/5500 element, and here's another link to some thoughts on my tank...

This is a cool idea! I run a 30 gal tank with a convertible 3800/5500 watt lower element which I've pretty much decided to leave on 3800. Description here http://www.garagejournal.com/forum/showthread.php?t=185015 . Two other advantages in building this tankless system is it takes less room...

I originally posted this is the General section, didn't get much response, thought it might fit better here. Sorry for the bandwidth. --------------------- Apologize in advance if this has been covered, I searched Ventilation and it would take forever to go through all the threads with...

Height -Re: best laid plans Just to chime in on the height - Even without a lift, you'll be bumping the ceiling or the lights at 8' and even 7' door operators will be tight with 8'. How tall is your truck? Get it up on jackstands and open the hood - tight. I have 9' and wish I'd gone higher...

Apologize in advance if this has been covered, I search Ventilation and it would take forever to go through all the threads with "ventilation" in their title. Somewhere, probably the Journal of Light Construction, I read about an automatic garage ventilation system with Heat Recovery for an...

Why Pictures? Re: Insulation Aggravation What's the big advantage in having pictures? 12x24, block walls, 2x8 rafters, unvented roof. The only thing we may have missed is the pitch, but really, now much more do you need to make insulation suggestions? Jonas

DanMan - With any insulation except foam you will need ventilation to prevent condensation and possible rot and mildew. Foam you can spray right on the plywood or sheathing. You can do a "flash and batt" wherein you spray about an inch of foam, then use fiberglas or other insulation to get...

Highbeam, thanks for confirming my suspicions. My heater has a lower element that is "convertible" from 3800W to 5500W by attaching a bus bar between two terminals. I have a 30A 240V SPST toggle with which I'm going to replace the bus bar so I can easily change between the two. After I get...

Seems to me it doesn't, and here's why. I have a 30 gallon electric domestic water heater as the heat source for my heated slab. You can see the building and system description in "Radiant Slab Recent Experience" here http://www.garagejournal.com/forum/showthread.php?t=185015&highlight=jrfiero...

Similar Setup If you look in my current thread Recent Radiant Experience you'll see I have a similar setup, radiant slab with a 2nd floor which is currently a woodshop but could be an office or guest quarters. I did not run radiant under the second floor, but would have if I intended to use it...
