5. Mahi
The Vaillant 061836 HW Heat Exchanger is a passive component within your boiler system. It does not have user-operable controls. Its operation is entirely dependent on the correct functioning of the main boiler unit.
Once correctly installed, the heat exchanger will automatically perform its function of transferring heat from the primary heating circuit to the domestic hot water circuit when there is a demand for hot water. Ensure your boiler is operating according to its own user manual to guarantee the heat exchanger functions optimally.
If you experience issues with hot water production after installation, refer to the troubleshooting section of this manual and the main boiler manual.
6. Tiaki
Regular maintenance of your boiler system, including the heat exchanger, is crucial for its efficiency and longevity. While the HW Heat Exchanger itself typically requires minimal direct user maintenance, it is part of a larger system that needs professional attention.
Nga Tikanga Whakapaipai Manakohia:
- Ratonga Pūwero ā-Tau: Have your entire Vaillant boiler system, including the heat exchanger, inspected and serviced annually by a qualified heating engineer. This will ensure optimal performance and identify potential issues early.
- Pūnaha Flushing: Periodically, your heating system may benefit from a power flush to remove sludge and debris that can accumulate in pipes and components, including the heat exchanger. This should only be performed by a professional.
- Mahinga wai: In hard water areas, scale buildup can affect heat exchanger efficiency. Consult with your heating engineer about appropriate water treatment solutions for your system.
- Tirotiro Ataata: During the annual service, the engineer will visually inspect the heat exchanger for any signs of corrosion, leaks, or blockages.
Always refer to your main Vaillant boiler manual for specific maintenance schedules and recommendations.
