Boiler Repair & Installation in Western Cape

Rule of thumb: if the boiler is over 10-12 years old, out of warranty, and the repair costs more than a third of a new unit, replace it. Newer boilers are far more efficient, so a replacement often pays back through lower running costs on top of ending the breakdowns.

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.

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.

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 plan spreads the annual check and often includes breakdown cover for parts and labour. It's worth it for older boilers or if a breakdown would be a crisis; for a newer boiler under warranty, a standalone annual service may be cheaper.

A repair typically runs R800-4,500 depending on the fault; a replacement geyser from around R6,000. Insurance often covers burst geysers, so check your policy — and insist on a Certificate of Compliance.
