System Boilers, Peterborough

A system boiler heats your central heating and stores hot water in a separate cylinder. Unlike combi boilers, it doesn’t heat water on demand, making it ideal for homes with higher hot water usage or multiple bathrooms. It takes water directly from the mains for improved pressure and efficiency.
