The Primus S range of electric system boilers is designed to provide all of your domestic space heating needs through a wet central or underfloor heating system. It is a direct replacement for a gas system boiler, and there is no need to change any radiators or pipes.

When used in conjunction with an unvented indirect hot water cylinder, it can also provide all of your hot water needs for larger and multi-bathroom properties. By integrating a timer with the boiler, you can use cheaper off-peak electricity to heat your water store, thus saving money, balancing the grid and utilising 100% renewable electricity.
