Heat pumps for sanitary water

Why do investors choose to buy ?

Apart from heating the house, heating the domestic water supply is the second biggest cost in the family budget.

In most cases, domestic hot water heating is provided in conjunction with space heating during the heating season. What about outside the heating season?
 Nowadays, it has become almost a matter of course to use a heat pump for domestic water heating or a solar thermal system. A solar system allows us to heat domestic hot water using the sun's energy, while a heat pump extracts the energy needed to heat domestic hot water from the air. Both sources are renewable and cost-effective.
