Hot Water
Inline Water Heater Repair
Inline (tankless) water heaters deliver hot water on demand without a storage cylinder — but when a sensor, element or gas valve fails, you lose hot water instantly. We repair gas and electric inline water heaters across Gauteng.
About this service
We service instantaneous gas water heaters (Rinnai, Paloma, Bosch, Junkers), electric tankless units (Stiebel Eltron, Siemens, Atlas), and point-of-use under-sink heaters. Our repair covers burner and ignition system repair, flow sensor and temperature sensor replacement, descaling of the heat exchanger, gas valve and solenoid replacement, and electrical board diagnostics. We carry common spares for the leading brands and can usually restore hot water in a single visit.
