Solar Hot Water

Summary: The best use of a roof is to put solar photovoltaic panels on it, but if there is extra roof space another energy-saving solution is to pre-heat water using solar energy. Solar water heating can reduce residential energy use by 12% to 17% (Drawdown).

Solar water heaters work best in hot, dry climates. They are mandatory in Cyprus and Israel and 90% of homes have them installed.

Goal: Use solar water heating where possible.
