Solar and Water Softeners
Do water softeners work with solar?
Water softeners use minimal electricity: 50-100 kWh/yr (regeneration pump and controls). On solar: completely free. Cost on grid: £12-£25/yr — trivial either way. More importantly: a water softener PROTECTS your solar hot water system. In hard water areas, limescale reduces immersion heater efficiency and shortens its lifespan. A solar diverter + immersion heater benefits from soft water: no limescale buildup = maintained efficiency = longer life. Combined benefit: solar (saves electricity) + softener (protects heating system) = maximum efficiency.
