How do you know if you're buying a quality heater? Is there any metric or efficiency rating to look for? Thanks

Anybody know the energy consumption of this? Let us say I run it in a small bedroom for 8 hours a day. I want to compare it vs cost of running thermostat whole night in a huge house where only 1 bedroom is occupied at night?

Secondly, is it sufficient to heat up a bedroom which is heated whole day with gas furnace backed thermostat, but then this heater is the only source of heat once thermostat is shut off at night for 8 hours?

Can't speak to the quality but every electric heater (and every electric device, for that matter) is 100% efficient by nature of being electric. In other words, this 1500W heater will be just as efficient as any other 1500W heater, regardless of price or features.

It'll be based on what your utility charges per kwh, and it might be a cheaper rate at night depending on where you live. Should be easy to figure given that the heater either pulls 900w or 1500w depending on what ya have it on. Just based off what you stated it seems like a given, to me anyway, that it would be a savings. Probably enough to pay for the thing in 30 days depending on your ft2 in the house.

Also, I don't care what anyone says, a $20 1500watt heater puts out the same BTU (heat) that a $100 1500watt heater does... Hell $1000 1500watt heater wouldn't hear any better either. Just say'n. I've heard it 100 times that a more expensive one heats better and it just don't, basic physics.

It consumes 900W per hour on low if it is running continuously. If the thermostat kicks on 50% of the time then it consumes 450W per hour or .45kWh. The math is easy. Also electric heat is near 100% efficient as virtually all incoming electricity is converted to heat.

The energy consumption is in the title. 1500 watts max. Whether that is sufficient for a room depends on too many variables to give an accurate answer. Turning off your whole house heat at night and only heating your bedroom with electricity is probably a money looser. Gas heat is cheaper than electricity and turning off and on your heat causes a lot of rework and wasted energy. You might benefit from reducing your central heat at night to a lower but reasonable number (say 60f) and using an electric heater in your room as an offset. But again this depends on so many variables nobody will be able to give you a reasonable answer up front. You'd have to either do an exhaustive heat load study or just trial and error it.

I'm thinking about getting a couple of these for a 160f dry sauna heater (safety circuits kick in at 180). Anybody have useful thoughts about that?

Lasko 754200 - was $22 on rakuten about a month or so ago. Worth paying $30 or less its very effective

Much nicer lookin than this, same power, more settings i think, and kicks the colds arse even when using on my porch in NJ temps in the AM/PM teens.

Very effective heating an entire room as well in such a clean tiny package. Surprised the pants off me (and the heat made me do it too)

1500W. My mining rig takes 900W. 1500W will cost you $108 a month @ .1 kw/h. (That's the avg power cost, check your bill for actual number).
