Question: What is the difference between the G56 and the G73 NewAir units? Thanks for the help.
Document: this unit was to replace my HeatStream,which melted one of the 120v thermos, which I fixed by using remaining thermo to control a contactor from amazon. ( Packard C240B w/ 120v coil) Or could use thermo from a Merkel heater,WAY better,NO plastic at all!
this heater is very disappointing. I turned it on in my shop thinking that in a little while I would fell a little heat. I could literally put my hand in front of the heater grill and hold it there without it getting to hot, I mean right on the grill! Come on, this is a 220 volt heater. If your wanting a heater for heating your shop find one that puts out heat because this one only puts out warm air.
and used it for a couple days this week in order to test it out. Its finally getting cold here in Michigan, mind you its not as cold as it will be soon, but cold enough to warrant a machine such as this on some days.Its relatively quiet for this type of machine. Definitely not soundless but nothing bothersome.I don't know the square footage of his garage off hand but it is a one car garage that is bigger than your standard one car garage in length as well as width.
after searching for quite awhile, I found the very thing I wanted to heat my garage @ AIR-N-WATER! !their site is VERY navigible, and they offer a great variety of products. anything you could ever want or need in electric heating.
Works great, thermostat is very consistent. Doesn't pour out a ton of heat but keeps up in an enclosed space.
When it gets really cold out this winter, we can probably just set it right in the middle of our tailgating tent and be good to go. It is an extremely safe device unless most of the common space heaters I've had in the past that are fire hazards or short out the electricity at home. Great product.
Unfortunately I haven't been able to test this heater when the temps were below zero with the area being insulated. This heater is stated to heat an area 500 sq feet but my area is almost 900 sq ft and it does the job to take the chill out of the area (even with a cement floor). Two of these heaters would EASILY heat my area to any temp (70 deg) no matter what the temp is outside. Remember, I live in a COLD area.
This thing is well built. Note that it requires a 240 outlet before you order. But it puts out the heat let me tell you. My son came over and mounted it up about 2/3 of the way up the wall opposite the garage door in a corner about 3 feet forward from the wall and plugged it in.
This is an amazing heater for the price. We only have a one-car garage but now that it has started to get chilly out, we bring it out there to do work remodeling our bathroom and it heats the space really fast. I would like to think it would handle it a two-car garage just fine as well (and it can, according to the specs).
This is a bit of a "buyer beware" review. This heater requires an electrical configuration (essentially having a "dryer plug" kind of socket in your wall).Not many garages have that. Mine didn't. In fairness, the description explains this and I missed it.If I were going to pay for an electrician to install the proper power, I'd likely ponder some other solution that wouldn't be as expensive.
Answer: no
