The checks depend on your hot water type. An electric cylinder is a large insulated tank, usually in a cupboard or garage. A gas califont (continuous-flow) is a compact wall-mounted unit with a flue. And it matters whether you're on mains pressure or low pressure. Knowing which you have tells you where to look first.
Never open up a cylinder or touch the element wiring yourself — it's mains electricity and water together.
If you ever smell gas, stop — turn the gas off at the bottle or meter, ventilate, and call a gasfitter.
Call in a professional if: the breaker keeps tripping, water is leaking from the cylinder, you smell gas, the califont throws an error or won't ignite, or you've checked the basics and still have no hot water. Taupō's cold winters put real demand on hot water systems, and they tend to give out on the frostiest mornings — exactly when you need them. Our hot water team diagnoses electric and gas faults fast, and we're on call 24/7 if you're left without.
FAQ
Common causes are a tripped breaker or failed element on an electric cylinder, or an empty gas bottle or pilot fault on a califont. Check those safely first, then call a plumber if it's not resolved.
On an electric cylinder that usually means one of the two elements or thermostats has failed, so you only get partial heating. A plumber can test and replace the faulty part.
Not usually on its own, but a leaking cylinder or a gas smell is. In a cold Taupō winter we treat sudden hot water failures as a priority and can come out quickly — call us any time.
