Why does my heat pump heat the hot water but not the heating system at the same time?

Air source heat pump systems do not provide space heating and hot water at the same time. Instead, your installer will have fitted controls, such as a two-channel programmer, that will control your heat pump by setting when it is working to provide space heating to heat your home and when it is working to heat your hot water. If there is a demand within your home for hot water, your heat pump’s operation will be diverted from providing space heating to providing hot water. As soon as the demand for hot water stops, your heat pump’s operation will return to providing space heating.
