Garage Heat

[BMS]

I saw some old threads but they are a few years old so wanted an updated reply. I have a 28x20 garage and am wondering what the average heat cost might be with a forced air furnace. The garage is 549 SQ FT if that helps any. The furnace would run on natural gas.

Also what is a good place to get a used/cheaper furnace? Not many on Kijiji right now.

Thanks!

Heating cost would depend on what temperature you keep it at and how well it's insulated. I keep mine at 4*C unoccupied and 17*C occupied (toggle switch) and it maybe adds $15/month for my 28x28 shop. Many of the wholesalers have scratch and dent deals for unit heaters. Check the websites for Refrigerative Supply, Independent Supply, Carrier / WWG. Personally I would buy new, but I'm a contractor and don't pay wholesale price.

Thanks. I will likely keep it around the same temp. The garage is brand new and is fully insulated and dry-walled.

Even if vented properly? I've never heard that before.

Agreed. Go Radiant Heat if this applies.

Does running the chopsaw every so often count as woodworking? From what I've read radiant heat doesn't work as well as forced air.

Using a mitre saw alone does not constitute woodworking. I prefer radiant heat because I always have sawdust covering my flooring and radiant heat doesn't stir it up. Also, I have several thousand pounds of cast iron ready and willing to absorb that heat.

If you plan on doing any woodworking in there, don't use a forced air furnace. You have a VERY high risk of explosion if there's wood dust in the air.

Gravity vent unit heaters are long gone. Everything is power vented now and can have it's own air supply from outside.

On a side note, high efficiency unit heaters are now common whereas high efficiency radiant heaters are impossible.

Unless u have a plumbing, refrigeration or sheetmetal journeyman ticket no one will sell you a new furnace or gas fired heating appliance. Typical install including permit will cost you 2700- 4000 depending on the unit you want.

Unless you buy it from Princess Auto.

In addition, if you do pick up a used furnace off of Kijiji you will have a very difficult time finding someone licensed who will pull a permit to install a used item. They only want to sell you new.

You know the wrong hvac people :D I have a contact who happily install a used furnace

[Fuzzybunnykiller]

This I what I do for a living I don't know people i am one of them. Any reputable retailer of gas fired appliance will not sell to the non ticketed guy. Insurance will not cover a gas installed app by a untrained person. Just ask the guy who had his brother inlaw install the gas fireplace in his house on cougar ridge and the house burns down. Investigation finds improper installed vent of the fire place and the guy owns a lot with a burnt house and basement no house left no insurance.

I will install a used furnace. There will be no warranty on the furnace just the install. And no guarantee that the heat exchanger is not cracked. See reburning products of combustion. I just want peaple to be aware of the risk. This is a buissnes to me but I still want others to be safe.
