Potterton Gold 12kw Heat Only Electric Boiler

At 12kW, the Potterton Gold 12kw Heat Only Electric Boiler is the biggest model in this electric range. It runs a wet radiator system on electricity alone, so it suits larger properties where gas is not an option but a full central heating system is still wanted.

Is the 12kW electric boiler right for the job?

Size an electric boiler from a heat loss calculation, not a guess. Going up to 12kW only makes sense when the house really needs it, because the supply has to carry the extra load. Where the numbers stack up, it gives you one unit for heating and, with the Potterton Gold indirect cylinder, stored hot water too. It runs on sealed or open vented systems with normal radiators, controls and TRVs.

Common Questions

What is a heat only electric boiler? It heats the water for your radiators using electricity rather than gas or oil, and doesn’t make hot water by itself. Pair the Gold 12kW with a Potterton Gold indirect cylinder if you want hot water too.

Do electric boilers need a flue? No, nothing is burned so there’s no flue. That makes the Gold 12kW easy to site and close to 100% efficient.

Can electric boilers heat radiators? Yes, the Gold 12kW runs a wet system with standard radiators and TRVs, controlled by a programmer, pump and room stat. It isn’t suitable for underfloor heating, though.

Does the Potterton Gold 12kW work on an open vented system? Yes, it suits both pressurised and open vented systems on 22mm pipework. It needs a flow of 6 litres per minute.

Who can service an electric boiler? It doesn’t need an annual safety certificate like a gas boiler. Any electrical work should be done by a qualified electrician, and a heating engineer can look after the system side.

Do electric boilers use a lot of electricity? Almost all the electricity it uses becomes heat, but what it costs to run depends on how much heat your home needs and your tariff. Good insulation and sensible controls make the biggest difference.

What to sort out first, says our Glasgow counter

Get an electrician to check the incoming supply and the main fuse before you buy, since a load this size may need upgrades. The boiler has solid state switching, a soft start, and status lights on the front. A min and max dial sets how hot the water leaves the boiler. With no burner and no flue, it runs quietly and there is no gas safety certificate to renew each year.
