What Are the Benefits of a System Boiler?


System boilers are ideal for larger homes with higher demand for hot water. Unlike regular boilers and combi boilers that heat hot water as required, a system boiler benefits from a constant supply of hot water stored in a cylinder.

However, the hot water supply runs out faster when multiple radiators, taps or showers are used, and it can take 30-40 minutes for a system boiler to heat more water. Overall, system boilers are reliable, efficient, and compatible with most central heating systems.
