Those are the ones wingboy already brought up. Radiant/infra red is the more common term but we know what you are talking about. They are great if you are just out for a few minutes as it is instant heat. If I am out for a while, I prefer a larger heater that actually heats the air as I find it more comfortable than one warm beam in the center of a freezing space.Heaters that heat you instead of the air around you Might be your best bet, you know like the ones outside at the airport?
I think Quartz heater might be the term you would be looking for
Wow. 6300 watts into a two car garage got you 15 degrees in an hour? That's good info.
A typical 4800W construction heater requires a 30 amp 240 volt receptacle. I use one to heat my double garage. I find it works much better if it’s on the floor rather than hung from the ceiling.
So the propane heater you were considering uses 1 lb propane bottles. That is probably the only fuel source more expensive than electricity. At 9000 btu, people are saying about 3 hours a bottle. At ~$9/bottle, you are at $0.33/1000 BTU. Electricity @ $0.15/ kWh is $0.04/1000 BTU. Damn, it's an order of magnitude more for small propane bottles.
Also, in the description "*WE ARE NOT ABLE TO SELL THIS PRODUCT TO CANADA AND MASSACHUSETTS* ". Yeah, I know it is on amazon.ca. Obviously there is something fishy going on.
EDIT:
From the manual:
"This heater requires a vent area of 9 square inches (example 3” x 3” opening) minimum for adequate ventilation during operation. Do not use other fuel burning appliances inside "
So you can operate it inside, but you need a vent. I wonder if that gets you a net heat loss or gain. I suspect loss.
I don't think this is true. Homeowners are allowed to do their own electrical work providing they have the correct permits (notifications) and they comply with current electrical code. There is limit on circuit size.Last night I had dinner with an electrician that had just attained his master's licence and while the conversation was mostly non electrical he mentioned some changes to the ESA code of which I wasn't aware. One was that while a homeowner can do his own electrical work (With a permit) the work is limited to circuits of no more than 30 amperes IIRC. Beer was involved so the number might not be accurate.
Haha. I was renting a basement apartment long ago. There was 18 or 20 gauge speaker wire going into the panel. Of course it went to a double tapped breaker. I disconnected it. A few days later my landlord asked why the lights and outlets in her powder room didnt work. I told her to call an electrician to fix her problem. She never did. I sure as hell wasnt going to die in a fire.Reminds me of when I bought my house. I had to upgrade the panel as the fuse sockets were corroded.
I had to get a permit, which I did, the utility had to come and remove the meter seal and meter to do the upgrade. The original homeowner ran a basement circuit into the panel using an extension cord, rather than unwiring it from the old panel, I just chopped it off outside the manel and left that circuit out of the refit. The ESA guy noticed the old panel sitting on the floor, and the orange extension cord that was run into the box. Start of sh&^show.
He made me yank a couple of panels off the walls adjacent to the new panel. We discovered the all the basement wiring was done with BX to the first connection then extension cords everywhere else. I had to open every single box in the basement for inspection. We had to remove 3 basement circuits and install 5 lights with pull switches to meet compliance.
I would have found and repaired the wiring eventually as I planned to renovate the lousy DIY everything the original homeowner did. I'm glad the inspector's great guess about more hidden extension cord wiring -- could have saved a catastrophe.
