I think, your going to run into code problems having both furnaces in the same utility room. Although an HVAC expert could confirm.

How do houses with dual furnances work? They have two utility rooms?

He means a garage furnace can't be in the same room as the house furnace. There's not supposed to be any air flow between house and garage with doors shut.

Yes this is what I mean. Two furnaces for two zones of the same house is fine in one utility room. That's common.

Ahhh, gotcha. That makes sense.

We debated between an infrared vs forced air and were 99% convinced on the infrared but:
- Space is always at a premium. These units end up taking up quite a bit of room versus installing overhead storage
- I couldn't find any data on spacing to car paint (Killramos mentioned the same thing earlier)
This is the second garage we have installed forced air on and have no regrets - inexpensive, heats up fast, services a triple garage no problem, doesn't take up a ton of room.

Who did yours and approx price if you don't mind me asking? I'm almost 100% sold on a forced air heater for mine before next winter.

I've got "a guy" who does random odd jobs for me so curious on what pricing you get. To supply/install a 45,000 BTU Reznor heater (incl. ~50' 2" steel gas line and a rough in for future boiler for above garage development) was $3,900.

I had a 10kw ouellet electric forced air heater in my garage for a couple months, was cheap and easy to install. First electrical bill I got was $800 keeping my shop at 15c during the winter so that was sold on kijiji

Decided to trench my backyard and run gas. At the same time I ran 2 runs of 3" pvc conduit and junction boxes for 100a service, Installed a Modine hot dawg 45kbtu and have been using that for 10+ years. Like others said, works great but you loose all your heat when you open the big door. Not really a big deal as it only takes 5-10 mins to bring back to temp. I don't even notice an increase on my gas bill using an indirect fired forced air furnace during winter so I think overall its the best value option. I think I spent a total of $1100 including a gasfitter pulling the permit, piping everything and he even tee'd off for my bbq.

A friend of mind has a large attached garage with in floor heating and a hot water tank running 60/40 teg water. I would way rather have this but the investment is large compaired to the other options. I guess depends on if you are willing to make the investment. This would be my choice if I had the money and my garage was empty. No way i would try and pull this off at this point because my garage shop is packed full of stationary equipment etc.

I personally would not waste my time with radiant heaters. Forced air heat spreads much more evenly and calcana charges too much for the hardware. It all depends on your application at the end of the day

I did the same thing. I already had 220v in the garage. 6000w heater in my triple garage is more than enough to keep my triple garage at 20C when it's this cold outside if I need it. I usually just keep it from 10-15C. Minimal addition to my monthly bill. I went with Dr. Infared heater off amazon for $250.

Do you have a link to the Dr Infared heater you bought from Amazon? I had a look but couldn't find anything. I've got a 2 car garage.

I've got 220v already and looking for something this winter that is cheap, easy to do and won't have a massive impact on my energy bill.

thanks

Energy use is directly correlated with standard of living. Use lots of energy, it's the right thing to do.

agreed, but I have a very low standard of living.

Easy fix then!

What about those tube style radiant heaters?

Those are awesome if you have the clearance height for them.

Tube heaters have a fuel efficiency of around 60%. No doubt Trudeau will ban them soon if he hasn’t already pledged to do so in the last week during his work vacation.

There will be an exemption of you are burning Saudi Hydrocarbons in it. Because they're #Eco and #Feminists.

Are heat pumps a thing here? In the past they seemed useless in the cold but some of the new ones seem decently efficient? Arctic heat pump claims a COP of 2 at ~-25C and 3.5 at 0C. So if it produces 3.5kw of heat for every 1 kw of electricity used that seems not too bad and at the least double the efficiency of a electric heater.

But I can’t really figure out how that translates into a monthly bill. I’m assuming gas is still king but the cost savings of not running a gas line and also getting AC in the summer looks possibly interesting?

Short answer. No
