This demo case has elucidated the potential for utilizing low-cost solar collectors for heating (and cooling) of indoor swimming pools in summer houses in Denmark to obtain energy savings.

Technical solutions for installing solar heating systems have been presented along with the estimated cost for the systems to give an indication of the economy of the installation versus the energy savings.

Further, the demo case has also shown, that the water volume of the pool can work as heat storage for the house offering the possibility to utilize low-cost electricity. In this way, the cost of heating the house and the swimming pool can be reduced.
