These incentives can cut the upfront solar hot water price or heat pump hot water price by a substantial percentage, often bringing the cost closer to a basic electric hot water installation. With lower running costs, many Greta homes see payback periods fall to just a few years, particularly when pairing a heat pump or electric hot water system with rooftop solar and using timers or smart controls to heat water in the middle of the day. Some homeowners also access an electric hot water system rebate when upgrading to more efficient models, making solar hot water vs electric hot water – or heat pump vs solar hot water – a genuine choice rather than a budget stretch.
Whether you need hot water repair, solar hot water repair, solar hot water tank replacement or a full new hot water installation, it pays to compare options like Rheem solar hot water, Rheem heat pump hot water, Rinnai solar hot water and premium systems such as a Sanden heat pump.
