What type of heating for garage - DIY Chatroom

OK,

I just finished insulating the garage… Man that expanding stuff is $$$$$! I also added the grey stuff as I had 4” left after the expanding stuff – better over kill than none seeing as there are bedrooms above the garage.

Anyhow, I have two registers in the garage which are connected to my HVAC and this is not code, so I have to cancel them. I fished 220V wire in the garage before closing the walls and ceiling with gypsum.

So my question is this: Which is more efficient – baseboard radiant heaters or one of those electric blown air type garage heaters? I am in Montreal and our electric is not quite as expensive. Those heat pump type heaters are VERY efficient, but ???? in comparison.

Any ideas are welcome.

Thanks in advance.

Neither.
Electric heat is 100% efficient.

The radiant may give you a more comfortable heat. but will take longer to warm up the garage then a forced air one.

While a heat pump PTAC may be more money up front. It will cost far less to use.

Oh Yeah, Far less!! I just did a comparison search and the heat pump is 300% more effecient. Cheapest one I could find for the space is 800 bucks.... Thanx,

Your welcome.
They are 300% or more efficient at temps of say 35 and above. As it gets colder, they lose efficiency. But, are still more efficient at 10° outdoor temp then straight electric heat.
