When purchasing a new or replacement system boiler, it is important to note that although the boiler unit itself is compact, you will need to have space for an additional sealed hot water storage tank in your home. These are often installed in an airing cupboard of a property.
You will need this additional tank because system boilers are supplied with cold water directly from the mains, they then heat the water in the boiler unit, once it reaches optimum temperature, it is then moved into a sealed hot water tank to use when needed, which is perfect for those who require instant hot water. If your home has plenty of space then a system boiler could be a great option for you.
The Potterton Assure is also available in a combi regular boiler, and the Assure System 18kW and 24kW are also both available as an LPG boiler.
As mentioned, the Potterton Assure 24kW is the most powerful system boilers in its range, with the ability to heat a home with up to 15 radiators and a bathroom. Meanwhile, many homes do not require this demand for central heating and hot water, in this case, the 12kW, 15kW or 18kW may be more suitable for your home.
