Brian Gaff was thinking very hard :
I do think that the two improvements I would appreciate on my old ones are.
The ability to use power not on economy 7 if need be, and some better
insulation when you turn it down so the heat comes out much slower. In the UK
the way the weather fluctuates needs both of these. I have otherwise been
happy with mine and no nasty gas or hot water issues or boilers to go wrong.
and the actual bill is not really bad at all compared with people with both
gas and electric as gas seems to have gone up a lot.
I had no idea that the system was changing. Seems a bit daft as if its just
a replacement item that should not fall fuel of regulations.
I certainly do not want any fans to be noise sources in my house.

The little experience I had of them, was in a flat. I was out working
all day and by the time I got home, the heaters had lost much of their
heat. To be fair, they were old units, using a simple temperature
controlled flap to release the heat and a user adjustable charge stat..
I thought at the time, it needed much better insulation and much better
control of the release of heat.
