What are Valliant boilers?

We at Frank Finn Plumbing are certified Vaillant boiler experts based in Whitton. Our knowledgeable engineers always vouch for Vaillant boilers when a replacement boiler is needed. Vaillant is probably the best brand of boiler available, with market leading products. Not just because they are well constructed, but because they also come with an exceptional 7-year warranty. Combi boilers are the most common types in the UK, especially in Whitton.

This is probably due to the little amount of space they take up and because they have no need for a hot water cylinder or a storage tank. The reason for this is they donít need a lot of space for installation, and they donít need a hot water cylinder or storage tank fixtures. If you need a steady and instant supply of hot water in your home without having to rely on stored water from hot water cylinders, Combi boilers are the perfect choice. Vaillant boilers guarantee the safety and comfort of your household.

When compared to other brands of boilers, itís clear that the Vaillant brand is much more efficient when it comes to energy and utility costs.

How do you determine your boiler requires checking?

Here are common error codes your Vaillant boiler may display:

boiling

Code F27: This means a condensate pipe is frozen.

Code F22: This means water pressure is likely low, a usual boiler fault.

Code F75: This shows that your boilerís sensor canít sense the pump to be running. A typical problem in well-used boilers that havenít been flushed or have recently had magnetic filters fitted.

Code F28: A lack of gas supply to the boiler or a defective ignition can bring about this error code.

Code F29: This means an extinguished boiler flame.

Odd noises coming from your boiler

Boiler emitting strange noises – Air getting in your boiler system is the usual cause.

Issues with thermostat

Thermostat problems – it’s better to get a new thermostat when the boiler’s thermostat starts intermittently switching the heating off and on or gives inaccurate readings.

Boiler keeps turning off

Boiler won’t stay on – Can be brought on by air in the system or malfunctioning pump, poor water pressure or poor water flow thanks to a closed valve or issues with the thermostat.

Radiator not getting hot

Radiator won’t get hot – You might find that your radiator isn’t getting hot or that only the bottom section is heating up and this can be caused by sludge or air build-up, or unequal distribution of heat.

No heat or hot water

Shortage of hot water or no heating – can be due to a faulty thermostat or motorised valve, a broken diaphragm or airlock, a broken valve or poor water level.

Boiler leakages

Boiler leakages – Never try fixing a leaking gas boiler if you don’t have the necessary training and qualification, instead, call on a Gas Safe registered technician to look at your dripping boiler.

Blown out pilot light

Switched off pilot light – can be brought on by a damaged thermocouple blocking gas supply to the boiler, or your building has no gas supply. A blown out pilot light or accumulated dirt in the pilot light compartment are also possible causes.

Falling pressure

Losing pressure – If your pressure gauge indicates “below 1”, the issue might be caused by either a water leak in the system or the pressure relief valve needing replacing or that the radiators were recently bled.
