Common Vaillant Boiler Problems and Solutions

Low System Water Pressure (Fault Code F.24)

Vaillant combi and system boilers are equipped with a low water pressure sensor to prevent damage from running dry. If you encounter a low system water pressure fault code (F.24), you can resolve this issue without an engineer by increasing the system pressure using a filling loop.

Leaking Diverter Valve

If you notice water leaking from your Vaillant boiler, it could be due to a faulty diverter valve. Vaillant boilers were originally fitted with plastic valves, which have since been replaced with brass alternatives. If your boiler is leaking, you’ll need to book an engineer to assess the issue and resolve it.

Intermittent Hot Water

If your boiler is experiencing intermittent hot water issues, it could be due to dirt and debris in the central heating system. This can block the plate heat exchanger and cause the boiler to overheat. To resolve this issue, the plate heat exchanger must be removed and flushed through with a strong chemical. To prevent the problem from recurring, consider booking a power flush with us.

Tips for Maintaining Your Vaillant Boiler

Annual Servicing

To ensure your Vaillant boiler operates efficiently and safely, it’s essential to schedule an annual service with a qualified engineer. This will help to identify and resolve any potential issues before they become significant problems.

Check the Pressure

Regularly check your boiler’s pressure gauge to ensure it’s operating at the correct pressure. If the pressure is too low or too high, this can cause issues with your heating system.

Insulate Pipes

Insulating your boiler’s pipes can help to prevent heat loss and improve the overall efficiency of your heating system. This can also help to protect your pipes from freezing during the winter months.

Bleed Radiators

Bleeding your radiators can help to remove trapped air and improve the performance of your heating system. This should be done at least once a year or whenever you notice cold spots on your radiators.

Upgrading to a Vaillant Boiler: What to Consider

If you’re considering upgrading your current boiler to a Vaillant model, there are several factors to take into account. These include the size of your property, your heating and hot water requirements, and your budget.

Property Size and Heating Requirements

The size of your property and the number of radiators will determine the type and size of Vaillant boiler that’s best suited to your needs. For smaller properties with limited space, a combi boiler may be the ideal solution. Larger homes with multiple bathrooms may benefit from a system or regular boiler, which can provide a more consistent supply of hot water.

Energy Efficiency

Vaillant boilers are known for their energy efficiency, which can help you save money on your energy bills and reduce your carbon footprint. When selecting a new Vaillant boiler, look for an A-rated model with a high energy efficiency rating.

Budget

While Vaillant boilers may be more expensive than some other brands, they offer excellent value for money due to their performance, reliability, and longevity. It’s essential to consider the long-term benefits and cost savings that a high-quality Vaillant boiler can provide.
