System Boilers

The system boilers we recommend are known for their high quality and reliability, making them robust enough to stand up to the highest of heating and hot water demands.

Efficient and economical
Ultra efficient and economical to run, RBHM installed system boilers incorporate many of the heating and hot water components found in a traditional heating system, making installation less disruptive and neater.

Space saving and attractive
The compact size of combo boilers means that they can fit perfectly into many locations, with the 27kW and 30kW models even fitting into a standard kitchen cupboard. With a smart design, they’ll also look great in your home, whether alongside cupboards or placed on their own.

Perfect partners
System boilers can be used with a wide choice of optional controls to maximise comfort and energy savings, and are also perfectly matched to our comprehensive range of hot water cylinders.

Choosing one of our recommended systems will ensure you will have a highly efficient solution and the opportunity to get a comprehensive 5-year guarantee across your entire system.
