Your hot water cylinder might be the most affordable battery you will ever own.
RNZ reports that households with solar can use their electric hot water cylinder as low-cost energy storage, heating water during daylight hours rather than spending thousands on a home battery, with conservative estimates putting the savings at around $1,000 a year. Our 2in1 heat pump hot water cylinder takes that idea even further. It integrates directly with solar PV and lets you schedule up to three heating periods a day from your phone, so the sun does the heavy lifting while your power bill takes a break.
