High temperature heat pumps entered the industry discourse last week following the announcement of a new system from Swedish company Vattenfall. The company’s compelling claims that their pump could directly replace gas boilers is an interesting one, and bears investigating, so can high temperatures really offer a Eureka product for homeowners?

Most air source source heat pumps and ground source heat pumps operate at a maximum flow temperature of 55°C, but in order to be efficient they are much better suited to running at flow temperatures of around 35°C to 45°C.
