I have an electric boiler, it is very good and very neat, silent, perfect.
Big downside is that it chews power extremely heavily. Make sure that you are happy to shoulder this. The reason we went this route is because i didnt want to keep the oil boiler and massive garden tank as we are outside of a gas area.
We now plan to sell the house medium term so i think i will leave it, but if we were to stay longer term i think i would go to the hassle and expense of an air source system to supplement it. If i could get gas i'd definitely do that.
This what I don't get about green plans to replace all gas boilers. There doesnt seem to be a decent alternative as while electric can be extremely efficient it costs far too much.
