Atmos Heating Systems’ Combinair hot water boiler combines a conventional boiler with an air source heat pump and heat recovery in a single unit, and is now covered by a new section in SAP Appendix Q. This means its energy saving potential can be taken into account when carrying out a SAP assessment
Designed to reduce CO2 emissions, the Combinair offers a route to achieving levels three and four of the Code for Sustainable Homes. When heating demand in the home is below 3kW, the air source heat pump supplies it, but when it rises above this, the condensing boiler cuts in to provide the extra heat.
