Tankless water heaters — also known as instant or on-demand water heaters — are increasingly popular in Kenyan homes and commercial properties for their energy efficiency and continuous hot water supply without the limitations of a storage tank. When a tankless unit develops a fault — displaying error codes, failing to ignite, delivering only cold water, or producing insufficient flow — professional diagnosis and repair is essential to restore on-demand hot water performance.
Bestcare Facilities Management offers specialist tankless water heater repair services across Nairobi, Kiambu, and Kenya. Our technicians understand the unique components and requirements of instantaneous water heating systems and deliver precise, effective repairs.
Why Tankless Water Heater Repairs Require Specialist Knowledge
Unlike storage water heaters with simple tank and element configurations, tankless units incorporate flow sensors, modulating gas valves or multi-stage heating elements, complex electronic control boards, and safety sensors — all of which must work in perfect coordination to deliver consistent hot water. A fault in any single component can trigger error codes and system shutdown. Accurate diagnosis requires familiarity with the specific control logic and error codes of different brands and models, making specialist technicians essential.
Our Tankless Water Heater Repair Services
Flow Sensor Repair and Replacement — Flow sensors that fail to detect water movement and prevent the heater from activating are cleaned, calibrated, or replaced.
Heating Element Replacement — Failed heating elements in electric tankless units are replaced with correctly rated components to restore instant heating capacity.
Gas Ignition and Burner Repair — Gas tankless units with ignition failures, weak flame, or burner faults are repaired by our gas-trained technicians.
Error Code Diagnosis and Control Board Repair — System error codes are read and interpreted to identify root causes. Faulty control boards are repaired or replaced.
Scale and Limescale Removal — In hard water areas, mineral scale build-up inside heat exchangers dramatically reduces efficiency. We carry out descaling service to restore performance.
Pressure and Temperature Safety Valve Replacement — Safety devices that have activated or are failing to operate correctly are tested and replaced.
Venting and Exhaust System Inspection — For gas tankless heaters, we inspect venting systems for blockages, corrosion, or incorrect installation that could cause carbon monoxide risks.
