do you know if and where you can get an oil filled radiator that looks like a normal rad ?

i want one to go in the utility but want it to look nice

You can get electric immersion heaters to turn a normal (CH type) towel rail into an electric one.

As they use the same valves this could also presumably be used on a radiator.. but i'm not sure if the output would be upto what a normal CH type radiator would be.

Is it just to take the chill off / stop frost?

I fitted one of these underneath the units in my utility (my units are on legs, rather than a plinth).




120w version is £15 and took the average temp of my un-heated utility from 5C to 15C.
