The Primus S range of electric system boilers are 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 mutli bathroom properties.
