Portable Electric Heater 120V

My 6X8 greenhouse is being heated with this great heater. I've seen no difference in my electric bill consequently I'm a happy customer. I live in the DFW area of Texas.

I bought this for night time winter heating of a small "sun room" facing south. Like some other reviewers, I found the control setting behaves erratically sometimes, so much so that I plugged it into a timer to make sure it does not start heating in daylight hours when the space is already well-heated by the midday sun! It does the job keeping night temperatures where they should be.

When this thing works as intended it's wonderful 5 stars. Keeps my small greenhouse above my set temp (55 degrees, as read by external thermometer probe) when it's freezing outside. However, about once every two weeks or so it will just refuse to turn on when the temps drop, or refuse to turn off when it's hot enough already. When that happens i usually turn it off and on again and it works fine. But I have to check it all the time to make sure it actually turns on at night to keep my tropical plants from dying, or to make sure my greenhouse isn't 120 degrees in the middle of the day (and wasting electricity) because it's blasting heat for no reason. So three stars as a compromise.

This is my second heater and works great for my little greenhouse. I live in Deep South and I already have really nice tomato transplants that will be ready to sell March 1st.

Got this as Christmas present for Moms greenhouse that houses her lemon trees. Quick shipping. Got it just in time for deep freeze after Christmas. Kept it 60 degrees inside while 10 degrees outside. No worries!

So far, this little heater is a winner. We have a 9x9x10 pop up greenhouse and this little heater on the 1500W setting keeps it 20' above the outdoor temp when outdoor temp is in the high teens to twenties. When the outdoor temp is going to be in the 30's and above I turn it to the 1300W for energy efficiency.

Works well but has very few features. It was sold as a portable greenhouse heater but the warning says DO NOT use outdoors and DO NOT use with an extension cord which didn't make much sense.

We have two of these in a greenhouse 20 feet wide by 78 feet long hoop-style with about a 8 1/2 foot peak and 2 x 12 baseboards with solid, insulated end walls. They are protected under another fan box for our geo-air system (2 fans, one at each end). The geo-air pulls about 50 or 55 degree air from four feet down through 1,000 feet (each fan) of that black four-inch non-perforated corrugated drain pipe. The heaters are under the fan boxes (one fan is 1/2 hp and the other is 1/4 hp cfm about 1,000) and pointed up into the fan air flow. I was surprised when I turned them on at half heat that I could see a 2 degree rise in ambient temperature within 15 minutes (43 up to 45 degrees) with an outside air temp of 26 degrees. They keep the inside temp well above freezing when running at full output. Our fish tank temperatures stay warmer too. Between these and our geo-air the temps stay above 50 even in zero-degree weather. Our energy cost is about 10 cents/kwhr so on full heat they cost about 40 cents each for an hour to run. Fortunately we only need to run them in December and January about every other day.

Bought this heater for 8x12 polycarbonate greenhouse. I like that it has a fan only position for air circulation and mostly have it on anti freeze setting. I had a radiator heater in there before. Awaiting my electric bill, but hoping to use this heater. So far, so good!

Heater was used during a hard freeze and kept my citrus trees in my greenhouse above freezing. Highly recommend!
