Boiler Repair & Installation in Wellington

Gas and oil boiler work is safety-critical and legally restricted to registered engineers almost everywhere (see country notes). Never let an unregistered person touch a gas appliance — carbon monoxide and explosion risks are real, and it voids insurance and warranties.

In Wellington, use only registered gas/heating engineers (check the register), get the diagnosis and parts cost in writing, and compare replacement quotes on the boiler model and warranty, not just headline price. Insist on the safety registration number.

Annually. A yearly service keeps the manufacturer's warranty valid, catches wear before it becomes a breakdown, and confirms safe combustion. Landlords are legally required to have an annual gas safety check in many countries; owner-occupiers should treat it as maintenance, not optional.

A simple service or minor part is inexpensive; replacing a failed component like a circuit board, pump or diverter valve is a mid-range repair; a full boiler replacement is the big-ticket job. Age is the deciding factor — past 10-12 years, repeated repairs usually mean it's time to replace.

Frequent culprits: no hot water or heating (diverter valve, thermostat), low pressure (leak or expansion vessel), pilot/ignition failure, strange banging (kettling from limescale), and leaks. Many are affordable fixes; a cracked heat exchanger is the one that usually condemns a boiler.

A service runs about NZD 120-350; common repairs NZD 220-950; a replacement from around NZD 4,000. Use only a certified gasfitter and keep the gas safety certificate for insurance and resale.
