    Your geyser quietly heats water around the clock — even at 2am when no one needs it. A GeyserWise smart controller fixes that, and it is one of the cheapest ways to cut your electricity bill. Here is how it works.

    What is GeyserWise?

    GeyserWise is South Africa's leading smart geyser controller. It schedules your geyser to heat water only when you actually use it — before the morning shower and the evening dishes — instead of maintaining a full tank 24 hours a day.

    How it saves money

    Because water heating is 30–40% of a typical bill, cutting out wasted reheating saves 25–35% on geyser electricity. It also shows you the water temperature and lets you boost on demand, so you never run cold or overheat.

    MAX vs TSE+

    The MAX suits most homes — a timer with temperature display. The TSE+ adds intelligent element control for solar geysers and heat pumps, only firing the electric element when free heat is not enough.

    What it costs

    A GeyserWise MAX installed starts from R2,500; the TSE+ from R3,200 — including mounting, wiring and commissioning. Most units pay for themselves in under two years.

    Frequently Asked Questions

    A GeyserWise smart controller typically saves 25 to 35 percent on geyser-related electricity by heating water only around your actual routine instead of 24/7. Since the geyser is 30 to 40 percent of most home bills, that is a meaningful monthly saving.
