I couldn't get gas heating where my house is, so I installed Rointe radiators for every room. I initially thought the cost was going to be very expensive but as it turns out its a actually quite cheap to run these.
I think the way they work is they come off and on a lot. When they are on they use the full power and when off just next to nothing (I could be wrong here).
The app is great too, I can control them from anywhere
