Proper Humidity control would be a bigger concern for me with garage slab heat vs heat recovery time.

The photos were just off google. But very similar to the house. I can reach a couple of them with a broom stick so ive got a few opened up. Tonight its getting close to -30C so ill address these when it warms up a bit

The duct work is installed, cause they open when its not super cold.

In our new house, we got a hip roof so the sheet metal guys vented the bathroom to the soffit. The flappers have been freezing closed not allowing air out. What can i do to remedy this problem?

Few days ago I found a deal on Kijiji and went and picked it up on my way from a trip to visit some friends. The sellers didnt really have any history on the boiler and got it a package deal for some other work they did for a heating outfit. Its a weil mclain cgi-4 which is perfect size for my...

Spent a little bit of time working on he solar collector area. Got it framed out and insulation installed, made a jig to make my own heat transfer plates.

What size boiler and what is you boiler water temp?

Will this be a hydronic unit heater? Glycol Supply temp plays a big role is btu output for these heaters.

Walk the plank mouse trap off amazon. Best investment ever.

Went through all the pages on this thread, really thought id see more mid efficient cast iron boilers. Im insulating a 2800sq ft shop and the local dealer has a good deal on a 85% efficient cast iron boiler thats been sitting in the crate for a while.

My 672 sq ft garage in alberta averaged 3000btu/hr requirement over last winter to maintain 5°C. 3000btu is basically 1 kw. Id say you have the capability, but do you have the wallet for it. 1kw x 24hrs a day x 30 days a month x 8 cents a kw. So 60 bucks a month if my 6am math is correct. My...

Ya the house is progressing nicely. Should be done by late december.

Got most of the wiring done. Onto insulation before it gets too cold.

Seems like alot of natural gas can be bought for 4500 bucks.

Hey guys, Were in the middle of a new house build and i need some opinions on the equipment that was chosen for my house. I asked for an HRV unit for my house cause it will have a large moisture loading once the salt water aquarium is set up. The heating contractor recommended skipping the hrv...

Zero progress on the inside of the shop, but the house is coming along nicely. Also got most of my water lines dug in.

Insulation for the shop showed up. And the crews started on the house finally after we postponed the house for years

Id say anything in a 75-100btu would be fine even. I just watched my garage all winter and it barely used 10 btu/sq ft on the coldest alberta winter.

I was using the monitor to see how often the fan runs. We pay little over $3 a GJ if i recall. My math came out around 10 bucks a month in gas charges. 45000btu x2hr a day x 30 days = 2.7 million btu a month. 1 gj has 948000 btu in it 2700000/948000 =2.85GJ of gas used a month.
