New Boiler Costs

Boilers can be a daunting purchase for many people as they’re an appliance with a lot of responsibility, providing heat for you and your family is something you want to get right. Boilers aren’t exactly a quickly disposable item either, potentially lasting you a decade.

By comparing different Vaillant boilers and considering the impact on energy bills, you can make an informed decision that works both economically and environmentally.

Common Issues and Troubleshooting

F22 Error

One prevalent issue in Vaillant ecoTEC Plus combi boilers is the F22 error code. An F22 error indicates low water pressure within the system. Low water pressure may cause the boiler to malfunction, consequently affecting its reliability.

To resolve this issue, open the external filling loop to raise the water pressure back to 1.5. Make sure to check the pressure sensor and circulation pump for any abnormalities as well.

Low Water Pressure

Low water pressure is a common issue in Vaillant combi boilers, particularly for the ecoTEC Plus Original Remastered 2023 model. It can lead to:

  • Reduced heat production

  • Inadequate hot water supply

  • Boiler leaks and potential water damage

To troubleshoot low water pressure, follow these steps:

  1. Assess the pressure gauge: Check the boiler's pressure gauge to ensure it reads between 1 and 1.5. If too low, proceed to step 2.

  2. Refill the system: Open the external filling loop, observe the gauge, and stop filling when the pressure range between 1 and 1.5 is reached.

  3. Inspect for leaks: Check pipes, valves, and joints for signs of leakage. If you find a leak, call a professional as soon as possible.

  4. Examine water flow: Assess the boiler's flow and return probes to ensure they are not broken or short-circuited. If damaged, seek professional help to repair or replace these components.

Bear in mind that regular maintenance and inspections are essential for maintaining the reliability and efficiency of Vaillant combi boilers. It is crucial to address issues like the F22 error and low water pressure promptly to ensure the prolonged functionality of the ecoTEC Plus Original Remastered 2023 Boiler.
