Electric Boilers

When connected to a Chelmer thermal store system, these boilers can be used as the sole heat source for a property's heating and hot water, or act as a backup for a solar thermal and/or wood burning stove system.

A-rated efficiency

All of our sealed system kits for boilers are supplied with separate A-rated pumps which modulate their speed to meet the current system demand for further reductions in energy bills. In addition, the lack of a boiler flue on electric boiler means that no heat is wasted up the chimney, making them 99.8% efficient.
