Water Heater Installation & Repair in Rotorua

Storage tanks: 8-12 years (longer with soft water and anode-rod changes). Tankless/instantaneous units: 15-20 years with descaling. Heat pump water heaters: 10-15 years. A tank leaking from the shell itself is end-of-life — replace, don't repair.

A leaking tank can fail suddenly and flood, and any leak near electrics is hazardous. Shut off the unit's power (or gas) and its cold-water feed valve, then call a professional. A dripping pressure-relief valve specifically signals over-pressure or over-temperature — don't cap it.

Yes: annual or biennial sediment flush, anode rod check every 2-3 years in hard-water areas, and TPR (pressure relief) valve testing. Tankless units need periodic descaling. Maintenance is the difference between an 8-year and a 15-year unit.

In Rotorua, a like-for-like storage tank swap is the baseline job; tankless conversions, relocations, and code upgrades (valves, drains, seismic strapping where required) add cost. Get itemised quotes separating unit price from labour and disposal.

Rule of thumb for storage: 30-40L per person per day of heated storage for typical use — a family of four lands around 150-200L (40-50 gal). For tankless, size by simultaneous outlets and the temperature rise your groundwater requires; your installer should calculate, not guess.

An unrestrained 180L cylinder is ~200kg of water that tears free in a quake, ripping out pipes and flooding the house on top of the damage. Building Code guidance requires strapping to structure — a cheap line item your installer should include by default.
