Tankless Descaling and Flushing in Wellington
Hard water leaves calcium and magnesium scale inside the heat exchanger, restricting flow and causing overheating. Many units warn of this with scale codes, such as the LC code on Rinnai models. We connect a circulation pump to the service valves and run a descaling solution through the exchanger. Annual descaling is wise for most homes on hard water.

Tankless Water Heater Descaling Service in Wellington
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, reducing efficiency and eventually causing breakdowns. Around Wellington, flushing the water heater yearly and descaling tankless units helps keep scale buildup under control. Our descaling service in Wellington involves flushing the unit with a dedicated cleaning solution to dissolve these mineral deposits. This preventative maintenance and repair step is key for extending the lifespan of your tankless heater and keeping it at peak performance.
Flow Sensor and Thermistor Repair in Wellington
Tankless heaters use flow sensors to start and thermistors to regulate temperature. A dirty inlet filter or failed sensor causes no hot water, fluctuating temperature or the unit turning off mid-shower. We clean filters, test sensor readings and replace faulty parts. Temperature becomes steady again once readings are correct.
