Garage Heater

[oler1234]

So am looking at buying a garage heater for my garage. Was wondering if anyone has any experience with the Princess Auto "Mr Heater" ones? They are 50000btu and going for $600. Would be heating a 22x22 garage.

My intial thoughts are that i dont have gas run out to the garage yet so was going to change it over to propane untill summer permits running gas out to the garage.

not sure on that one. i have a 20x22 with a 240 volt construction heater. Have it just on one click... keeps it around -5 up to +5. Its not BAD im not going to be in this house more than another 1-2 years, and my neighbor did the same thing and he says his power bill is about the same with the AC unit running in the summer....

Mine is a detached garage... i had to trench for the power and we wired it so we planned for the 240 plug.

Also if i want to work on the sled i turn the heater on full blast for and hour and its +15 in there.

I hung an electric unit heater in mine. Easy, peezy...No gas lines to play with and it works fine for as often as I'm out there. If you're trying to keep it heated all the time could get a little expensive though.

 

[oler1234]

yea i dont have 240 out to the garage... so that would be out. And electric would be expensive. Thats why i was thinking a full install and use propane for now. Inital cost is more as well install but final product would be good. Just wondering if these Mr Heater units are any good. They seem to sell and stock alot of them.

I'm just going to buy the dual tank top heaters for our garage, its a 16 x 22 and it will work for when I need to work on stuff in there or thaw out a frozen sled......

Is it this one?....

If so, its a copy of a hot dawg and I have that one in my garage. They are great as with the power exhaust, you are able to side vent out the wall of a garage instead of going through the roof. Mine works awesome. That $600 price tag is very good and very similar to what I paid for the dawg..... I have the 45,000 btu hot dawg and it heats up my 24X24 garage in no time. I'm looking at getting another for my new hobby/sled shop in the backyard soon too.....

I wouldn't be afraid to get the unit from princess auto, it even comes with a thermostat. Just make sure to get an appliance gas fitter to change the orifice to propane. I'm going to go check out that one from princess....looks good.

i bought one... still sitting on my freezer as i ran out of time this fall haha. but it came with 2 manuals one for natural gas and one for a propane conversion, i think you can even order them already fitted for propane. it would say on the box

Buy a stove that can burn wood or coal. Problem solved. Cheapest option in the short and long run.

You can get the same heater from Home Depot for 689, so 599 is a good price. I'm moving into a new house in March and planning on putting a heater in it as well. I may just ignore it this winter since there will only be a few more weeks of freezing temps in Calgary by the time I move in. Looks like a good option and there is a propane conversion kit you can buy for 39$.

50,000 btu's is lots for a 22x22. One note on the comment about sidewall venting. if you are having it inspected, new residential code requires all sidewall venting for unit heaters to be AL29-4C. It's stainless steel and its pricey so if it is possible, roof vent it OR don't get it inspected and use b vent out the wall. (although in case of a fire it may void insurance??) they were vented with B vent for years and never had an issue. i am not sure where you get parts for Princess auto heaters but you could get universal parts should you have issues with the heater.

The most important part of a propane conversion is adjusting the gas pressure AND changing the orfice. Unless you like things that go BOOM.

so does that mean all the exahust ducts inside and outside need to be stainless steel, OR just the piece that goes through the wall and outside? As well there instructions say to only have min 3ft and max 5 ft for with 1-90bend for side wall venting. I didnt think there was a limit on length of exahust ducting.

and adjusting for gas pressure??? you mean proapne pressure? Was just going to run it off a 40lb propane bottle for starters

He means the regulator that is on your 40 lb bottle is set way higher than what the heater will require and it will need a secondary regulator to drop the pressure down. Just like your RV doesn't run bottle presure through the lines it has a regulator right at the tank connection.

Residential Propane setup's have two regulators one on the tank and one on the house.

Just the penetration of the wall needs to be stainless duct and yes there will be a min and max on the distance. If the duct is longer than the max it will not run as it will sense too much back pressure.

Any afternoon is fine...

This is the second winter I've been running one in my shop. I'm heating 12x24 right now and expanding to 24x24 this summer. I keep it at about +10c all winter and I don't even notice it on gas bill.

They sell the same heater at Home Depot, and they have more parts for it on their website.
