What is a system boiler?

A system boiler is a type of central heating boiler that heats water directly for radiators and can store hot water for taps, all while being connected to a sealed system that contains all necessary components.

What are the suitable applications for a system boiler?

System boilers are suitable for larger homes or properties with higher hot water demand, as they can provide a continuous supply of hot water to multiple outlets simultaneously.

Are there any limitations to using a system boiler?

Yes, system boilers may not be ideal for smaller homes or flats with low hot water demand, as the size of the system can lead to inefficiencies and higher running costs.

How often should a system boiler be maintained?

It is recommended to have a system boiler serviced annually to ensure optimal performance, safety, and compliance with regulations.

What should I look for when assessing the energy efficiency of a system boiler?

Look for the energy efficiency rating, typically indicated by an A to G scale, and consider factors such as the Seasonal Efficiency of Domestic Boilers in the UK (SEDBUK) rating and any energy-saving features.
