It is important to note when purchasing a new or replacement system boiler, that you will need an additional hot water storage tank, which is typically located in your airing cupboard. If you have a smaller home with limited space, a combi boiler may be a better option. However, if space is not an issue in your home, then the Promax system boilers might be a perfect choice for you.
The Potterton Promax 32kW is the most powerful of its range, with an output of 32kW, which is ideal for a larger home with up to 20 radiators and a bathroom. Meanwhile, many smaller homes will not require this demand for heating and hot water, in this case, the 12kW, 15kW, 18kW, or 24kW may be better suited for your home.
