Common Bosch Tankless Water Heater Parts We Replace
Bosch tankless water heaters are known for their efficiency and reliability, but like any high-performance appliance, individual components may wear down over time. Here are the most commonly replaced parts we service at HeatLand Heating & Cooling:
1. Flow Sensors
Flow sensors are crucial for detecting water flow and initiating the heating process. A damaged sensor can prevent the unit from turning on or cause inconsistent heating. We replace Bosch flow sensors with OEM or compatible parts for seamless performance.
2. Heat Exchangers
The heat exchanger is the heart of your Bosch tankless unit. If it becomes clogged, corroded, or cracked, your water heater won’t be able to heat water effectively. Our team can replace this essential component to restore full system function.
3. Ignition Electrodes and Flame Rods
If your Bosch unit fails to ignite or frequently shuts down, faulty ignition components may be the cause. We carry replacement electrodes and flame sensors compatible with Bosch Greentherm, Therm, and ProTankless series.
4. Control Boards / PCBs
The control board governs every part of your Bosch tankless water heater. A failed PCB may result in error codes, irregular water temperatures, or complete system failure. HeatLand technicians can diagnose and replace this intricate component quickly and safely.
5. Water Valves and Mixers
Over time, hard water deposits can clog or corrode internal valves. Replacing faulty water valves helps restore full flow capacity and accurate temperature regulation.
6. Gas Valves
The gas valve controls fuel delivery to the burner. If your Bosch heater isn’t producing heat or is leaking gas, replacing this valve is critical for both performance and safety.
7. Temperature Sensors (Thermistors)
These sensors help the system detect water temperature in real-time. Inaccurate readings can result in scalding or freezing water. Replacing faulty thermistors restores consistent hot water delivery.
8. Air Intake and Exhaust Fans
Proper venting is essential for combustion and safety in gas-powered Bosch tankless models. A failed fan or clogged intake system can trigger errors and pose safety risks.
9. Condensate Traps and Drain Lines
Condensate drainage is critical for Bosch condensing units. A blocked or damaged drain line can trigger water leaks or system errors. HeatLand can replace or clean these components to prevent further issues.
10. DHW Sensors and Flow Control Modules
Advanced Bosch units use digital water flow modules to regulate performance. HeatLand technicians can replace these parts in newer models like the Bosch Greentherm C 950 ES or 9800 SE series.
Full Support for All Bosch Tankless Models
