Setback controls play an important role in helping your heat pump run efficiently and cost-effectively. Unlike traditional boilers, air source heat pumps are designed to operate continuously rather than being switched off completely. Turning the system off can actually reduce efficiency and comfort.
A setback control is a programmed heating schedule, usually set up by your installer using the Grant heat pump controller. It allows your system to automatically adjust temperatures based on occupancy patterns.
When you’re at home, the heating operates at your normal comfort temperature. During unoccupied times or overnight, the setback function lowers the target temperature slightly, rather than switching the system off. This steady approach keeps room temperatures from dropping too far, meaning your heat pump doesn’t need to work as hard to bring your home back up to temperature.
By maintaining a more consistent indoor climate, setback controls help your heat pump operate at lower flow temperatures, improving overall efficiency and reducing energy use.
Recently, we have noticed that due to the cost-of-living crisis, many
homeowners have decided to turn their heat pump off in order to try save
money on their monthly heating bills, however, to ensure high efficiency and cost savings, it is advised that the heat pump should never be switched off and thermostats should remain consistent (or decreased by 1 or 2°C maximum). Turning off your system will mean that once turned back on, the heat pump will have to work extra hard in the colder months, using a lot more electricity, to reach its optimum performance level once again.
