Upgrading from an older gas or electric hot water system can slash your annual hot water energy use, with many Cowes homes seeing sizeable Annual Hot Water Energy Savings when they move to a heat pump hot water installation or solar hot water installation. With over 4,100 occupied dwellings and a relatively older population, reliable, low-maintenance hot water is just as important as keeping bills manageable.
Across Cowes, detached homes dominate, and hot water demand is steady rather than extreme, which suits both a compact heat pump hot water system and a roof-mounted solar hot water heating system. Many properties already have solar PV, so choosing between heat pump vs solar hot water often comes down to roof space, budget and when you use your hot water. Brands like Sanden heat pump systems and Rheem heat pump hot water units are popular for quiet, efficient operation, while Rheem solar hot water and Rinnai solar hot water options suit households wanting maximum use of the sun. For those who prefer a more traditional setup, a modern electric hot water system with smart controls can still be an energy efficient hot water system, especially when paired with solar.
