What We Think of the Potterton Promax System HE Plus A

There are a wide range of outputs available in this range with outputs starting at 12kW, working up to 32kW. The units in between are 15kW, 18kW and 24kW. This means that they can handle anything from a flat to a medium sized house.

They are system boilers, which means that they use a hot water storage tank which provides a large reservoir of hot water for use when needed. A system boiler is a closed system, which means that it does not require a cold water cistern, nor does it need an expansion tank. But, unlike a Combi boiler which produces hot water on demand, because it has the water tank, the larger units can cope with providing hot water for say an ensuite bathroom, or a second bathroom.

It weighs in at around 38.6kg, which is slightly heavy for this type of boiler. The controls are basic, but will allow the user to do most things.

Getting a competitive Boiler Quote

We advise you to shop around to get the best boiler quote. For example, get a quote from a national and reputable installer as well as a quote from a local boiler installer.

You should also take into account the safety record of your prospective boiler installer and how flexible they are. All boiler installations should be carried out by Gas Safe Registered Engineers.
