Question: is it energy efficient
Document: keeps one large room warm very well. It will use a lot of energy to do so but the room I have it in has no heat at all.
It's perfect for small rooms, I justthought it would be more efficient in my living room, but I need new windows so that is probably the problem. Overall it's a nice heater.
DO NOT BUY THIS PRODUCT! It claims it will save you money and it is a dirty lie! My energy bills have tripled. This product drains twice as much power as two ten year old air conditioners powered on all day.
We suffered for asthma with our gas forced air house heater. We bought this to help heat the kitchen in the AM and then we merely turn it round to face the living room at night. Now we find in the AM, if we turn on the house heater for only 15 minutes and then let this unit take over, heat is maintained. It has really reduced our energy cost and helped greatly with the asthma. Nice little unit.
I bought this to supplement my heat. As everybody knows the winter of 2013-14 was long and cold. I live in Northern NY a little over an hour south of Ottawa, Canada. The first month I used this my total utility bill was $284, but I had also been using smaller heaters which were less energy saving. That was for February. March's bill was $175. All things considered if I had used oil it would have been more than double.
Even with this small space, the heater struggles to heat beyond 73 degrees F. I have to switch my home heater to get the temperature to &#62; 75 degree F.The construction is really solid and overall build quality is good. I think it consumes the same amount of energy as my home heater (i.e, the default heater installed in the apartment which runs on gas + electric fan i think). I have not seen a drop or rise in the electricity bill as such.
I could use it in a smaller area as a continually on device. I may add a fan to circulate the heat. It is a keeper.The Pelonis is the most efficient--instant and rapid heating. I plan to buy another B-6A1 classic 4 Disc Furnace with thermostatic control, although I am apprehensive that the new ones do not have the same build quality of my original--that original is over 20 years old and still functioning like new. Nothing is built like it used to be.
great heat I use it for an open room high ceilings, big windows, heats up the room in less than 45 minutes.
for our use, it works pretty well.- Sometimes this heater turns on for a few minutes then off when the temperature is 5 degrees warmer then what we have it set to.
bought this as a gift for my elderly in-laws to augment their baseboard heat and they absolutely love it. it heats great without drying out the air in their living room, where they spend most of their time watching t.v. also, very quiet and the remote is very easy to use.
Answer: yes
