Vaillant engineers in Whitnash
Working on Vaillant boilers every week
Vaillant boilers tell you a lot when they go wrong. An F22, F28 or F75 narrows the problem down quickly, which means less time hunting and more time fixing. We work on ecoTEC plus, ecoTEC pro, ecoFIT pure and the older ecoTEC exclusive. Serving Whitnash and the surrounding Warwickshire area.
Most Vaillant call-outs we attend fall into a handful of categories: pressure loss, ignition failure, pump or pressure sensor faults, and diverter valves that have stopped moving. All of them are testable rather than guesswork.
We service Vaillant boilers to the manufacturer's schedule so warranty cover stays intact, and we install new ecoTEC and ecoFIT boilers with the warranty registered for you.
Vaillant hold their value as an appliance, so where a Vaillant is repairable we will usually say so rather than push a replacement.

- ecoTEC and ecoFIT repairs and fault diagnosis
- F22, F28 and F75 lockouts resolved properly
- Annual servicing to Vaillant's schedule

Servicing and warranty
Keeping your Vaillant warranty valid
Vaillant warranties require an annual service by a registered engineer with the service record completed. Miss a year and the cover can be refused when you most need it.
We follow the manufacturer's own service schedule, test combustion with a calibrated analyser and leave a written record every visit, which is also the paperwork a buyer's surveyor will ask for later.
For landlords we combine the Vaillant service with the CP12 gas safety check on a single visit and email both documents the same day.

F22 is low pressure. Topping up treats the symptom. The cause is a leak, a failed expansion vessel or a passing pressure relief valve, and until that is found the pressure will keep dropping.
Yes, provided the boiler is serviced annually by a Gas Safe registered engineer with the service record completed. That is exactly what we do.
Yes for current ranges, and we carry the common ones. Parts for much older Vaillant models can be slower, and we will tell you honestly if availability is becoming the real problem.
Yes, sized from a proper heat loss calculation, installed cleanly and registered with Vaillant so the full warranty runs from day one.
