Potterton Promax Ultra 24kW - a regular, combi or system boiler?

Suitable for a house or a flat, the Potterton Promax Ultra 24kW heat only boiler is worth considering if you want a heat only boiler.

You may hear a heat only boiler being referred to as a conventional boiler, a standard boiler or a regular boiler, but they're all the same. Heat only boilers require both an immersion and a cold-water tank to function, the latter usually being situated in the loft. Water is kept warm throughout the day by the immersion cylinder for use when needed.

With a heat only boiler, you program the times at which you want to have hot water and central heating, but if you forget and there's no hot water left, you’ll have to wait for it to heat up before you have your bath or shower.

If you have a home with more than one bathroom, or a larger family, a heat only boiler will probably suit your needs. This is because, if you opted for a combi boiler instead, the water pressure, volume and temperature drop when more than one point is in use - for example if you have a shower while running hot water in the kitchen or another bathroom.

Boilers manufactured and installed in the UK are assigned energy efficiency ratings following testing to an agreed set of standards. These scores indicate how much energy the boiler uses and how much goes to waste when it's in operation.

By law, boilers must achieve a SEDBUK rating of "A" subject to achieving a minimum of 92% energy efficiency. Prior to April 2018, the minimum was 88% (88% and 89% on the SEDBUK are graded "B" and 90% and above is graded "A").

The Potterton Promax Ultra 24kW was awarded an efficiency rating of 89.1% with a SEDBUK band rating of "A".
