The Task aims at optimizing combinations of solar thermal energy and heat pump, primarily for one family houses.

The following items are in focus:

• Small-scale residential heating and hot water systems that use heat pumps and any type of solar thermal collectors as the main components.
• Systems offered as one product from a system supplier/manufacturer and that are installed by an installer.
• Electrically driven heat pumps, but during the development of performance assessment methods thermally driven heat pumps will not be excluded.
• Market available solutions and advanced solutions (produced during the course of the Task).
