Before you spend six figures on solar, there is a R-few-hundred upgrade that quietly trims your hot-water bill from day one: insulating the geyser and its pipes. Here is whether it is worth the bother (spoiler: usually yes).
What a geyser blanket does
Your geyser loses heat through the tank wall all day, so it switches on repeatedly just to stay hot — even when no one uses water. A geyser blanket adds insulation around the tank, slowing that standing heat loss so the element fires less often. On an older or thinly-insulated geyser, the saving is real and the blanket pays for itself within months.
Why pipe insulation helps too
The first metre or two of hot-water pipe leaving the geyser radiates heat between uses. Lagging those exposed pipes means less reheating and hotter water reaching the tap sooner — less water (and power) wasted waiting for it to run hot.
The smart pairing
Insulation tackles standing loss. A GeyserWise controller tackles unnecessary heating by only heating around your routine. Together they hit the two biggest hot-water wastes for very little money — the obvious first step before solar or a heat pump.
Worth it?
For the cost, almost always. It is part of any sensible energy-efficiency plan and pairs naturally with a geyser service. Ask us to insulate and optimise your geyser — or see hot water systems for the bigger upgrades.
