Shower room radiator on heating circuit?

That's because it would need new pipes run from the water heating circuit which probably only exists in the bathroom.

I assume the problem is that only the central heating zone passes nearby.

If you don't want to run new pipes, then consider using a hydronic towel radiator with built in electric element. When the central heating is on, it will be warm conventionally. In summer, you can set the element to go on an hour before your bath. Assuming a 1kW element, that will cost you around 6p every time you want a warm towel, which is probably not that much more expensive than running the entire central heating system (and all its primary circuit losses) for an hour just to heat a tiny single radiator.

Thanks for the answer, apparently it is not possible to connect to the existing water heating circuit because it has been done wrongly(?) so a new connection would have to be made to the pipes near the hot water tank.

Thanks for that advice Christian, it looks like the simplest solution.

The water heating circuit will go near enough the shortest way from your boiler to hot water cylinder - so I'd say it's rather unlikely it goes anywhere near the new shower room. It would mean running two new pipes.

Just about to do this myself using one of the chrome ladder style towel radiators from Screwfix (around £100) and an electric element from B&Q (£25-35).

Thats a lot cheaper than the ones I've been looking at Thanks Jeremy!

Do you fill the radiator with water / oil / what? Fill it totally or leave some expansion space? how much?

Am interested in doing the same- SWMBO insists on keeping our existing hot water style towel rail but its impractical to run CH pipes to its new location...
