So far I'm very satisfied with the heater. But I must say that I live in an apartment and my flat is well insulated and has south exposure so when the sun is up it is really hot. The outside temperature varies but even at -5 Celsius it managed to heat the room up to 24 degrees. The room is 20 square meters and has only one outside wall other walls are internal. If you have problems check form the app if the limit of the panel surface temperature is set too low. By default it is set to 120 degrees celsius but It can be set to 90. This is helpful to prevent burns on pets and children but limits the output of the device.

I can’t really tell about ut the bills for certain. Last winter was pretty mild and the bills were half of what I usually pay but I don’t know if it was because of the heater. Also electricity prices go up and down around here. I think you should get one or two to try and if you are satisfied you can scale up.

@@NikolaTubeNikolov Thank you so much for your reply Nikola. This will be the best solution, to get one and test it. Then we will see what will be the result. Thank you again! Greetings from Plovdiv, Bulgaria! P.S.: I suppose, we are from the same country btw, from the content in your chanel ^_^

Yep we currently live in an apartment and it’s fairly well insulated so in mild winters it did manage to heat the whole Living Room which is 20 sqmeters.

Also the app for iOS is very simple and works great. From there I can see that the panel consumed 300 kwh for the last winter and this November.

It draws about 720 watts according to it’s own app. I haven’t yet tried to measure it in any other way. The way it radiates heat is very pleasant and I personally can stand near it without problem even very close like 20-30 cm. 2 meters you barely feel the warmth but it manages to heat the 20 square meter room that we use it in. However we use it in an apartment building which is very well insulated.

Last winter wasn't very cold. Coldest temperatures were -10 C. For apartments and well insulated rooms it works great. I really like it. I added some Apple Shortcuts to turn it on and off. It is small and looks good. The room that I'm heating is 20 sq.m. but it is well insulated. I've heard other people that they don't like it and it doesn't do a great job but for my setup it does.

@@NikolaTubeNikolov Well, i need 3 panels, but i will buy only one for this year just for testing. Thanks 4 your feedback Nikola!

@@frps13 yes, this is a good strategy.

What are you trying to heat up? This one is made for rooms of up to 20 square meters. Also it helps if the room is fairly well insulated. I use it in my apartment and my living room is about 20 square meters but is well insulated and the room is facing south.
