Water radiators from an immersion hot water system???

Postby StrangerUK » Mon Oct 22, 2007 5:13 pm

Hello all

I have a flat with electric only, no gas. Hot water is from an immersion tank. I have no heating, so using oil-filled electric heaters.

I know little about DIY so here's my daft question - can I not have traditional water radiators running off my hot water system? Water radiators in my opinion gives off a nicer radiant heat, which is much better than these plug-in rubbish that I got. Can not the hot water pipe supplying my sink in the kitchen be extended into my lounge to feed a water radiator? I know that it probably would use most of the stored hot water in the immersion tank, but at least I'd have heat and the tank would heat up again in about an hour. Is it possible, and is there a company out there that can do it for me?

Thanks in advance,

Simply Build It

You can get electric combination boiler, that will heat radiators and hot water, but I think they're quite expensive.

You could not pipe up radiators using the hot water from your tank, as there is no circulation, the water would only flow if the taps were opened. So your radiator would be warm, when filling a the sink, maybe 5 minutes a day ?

plus the water would discolour eventually as the radiators get older

Ah well, worth a try. Perhaps I'll get a couple of more years out of the immersion heater, and then consider swapping to one of those combi boilers you mentioned.
Thanks for replying :)

Current cost of an electric boiler with a cylinder ie combi is around £1000 + vat. I think it has a 9Kw out put for radiators. Sold a few but I would not like the electricity bill to run one.
