Question: Does anyone run these heaters when you are not home?My sister lives in country and always turns off her heaters when she leaves.
Document: I live in BC Canada and live in an older home. I took temperature readings around the house before and after installing these heaters. I have 5 of them in 3 bedrooms and two large hallways. My old energy consumption was 7500 watts per hour for the 5 old heaters. Currently my new heaters use a total of 2000 watts per hour and far more efficient so they run less than my old heaters. That is a 73% Energy savings!!!
This is an awesome heater for young children. We put it on a timer so that it comes on when our house heater turns off at 10:00pm and then we turn of this heater when the house heater turns on at 4am (I know, I get up early.) You can touch it without burning yourself. We keep our home @ 62 degrees at night this little heater keeps our babies 10 x10 room @ 70 degrees no problem.
When you first fire these heaters up, they have a toxic smelling scent off the heaters. NO! IT'S NOT ACTUALLY TOXIC but enough to take notice and go on-line to see if this stuff is safe to breath. Turns out it's a protective coating (for shipping purposes) that needs to burn off for 8 hours to one day. After you burn it off, there is no scent at all.2) No instant gratification.
We have a bedroom on the north east corner of the house over the garage. Even though the house is well insulated this room is always colder than the rest of the house. This year was especially cold in Colorado. My friend told me about these heaters so I ordered 1. It really keeps the room nice and warm. The only thing I don't like about it is it gets hotter on the outside than I expected. You would not want to install this in a childs room.
My energy bill has gone down by 70% from the previous year. It maintains the temperature of the house better than any heater I have ever own...short of a Central Heating unit and those cost alot more to run than these heaters. So if you have a bedroom or a place with pets or kids where a heater can be a fire hazard (under 120 sq feet), then this heater will work great to get the chill out of a cold climate area.
If it takes longer then 10 minutes then you have problem following instructions  Believe me it is very easy.Pros:-Very quiet-Very easy to install so anyone can install it - I did.
This was a gift for relatives. Their home has a large door on the north and they use this to add heat to the bedroom. The fact that it is paintable is an added bonus.
I am very impressed with how easy this heater was to install, and how good it works! We are using it an approximately 10x10 room that is not insulated very well, and usually very cold. This heater made all the difference in there!I would definitely recommend it to anyone who wants to heat a smaller room inexpensively; safely; and easily!
For background, this is in an 11x13' bedroom in an old 2x4 frame house at 7,200' altitude in the Rockies- it gets verrrry cold at night, and is often below zero at this time of year, and our rural electric rates are high.My north-corner bedroom is always much colder than the rest of my house.
I have been real happy with the Econo-Heat Heater, easy to install , quite , easy to use and well built. Also is not an energy hawg. I would recommend this to anyone looking for a heater.Not this heater is best for heating smaller rooms, due to the convection style heating system.
