Many air-to-water heat pumps are combined with boilers. In retrofit projects, it’s likely an existing boiler; in new projects, it’s likely a mod/con boiler. The boiler can provide supplemental heat during very cold weather. It can also serve as a backup heat source should the heat pump become inoperable.
