What we do
Vaillant boilers in Aberdeen in Aberdeen and Aberdeenshire.
Vaillant boilers tend to outlast their warranty by a wide margin if they're looked after properly. The ecoTEC plus and ecoFIT pure are the workhorses of the Aberdeen landlord market — they're efficient, they take a beating, and parts are easy to source. We see Vaillants every week, know the common faults, and carry the consumables on the van for first-visit fixes.
Brands: Vaillant ecoTEC plus, ecoTEC pro, ecoFIT pure, plus older ecoTEC Sustain and Turbomax models where parts are still available.
When to ring us about a Vaillant
- F75 fault — pressure sensor or pump issue, one of the most common Vaillant codes
- F22 — low water pressure, often a leak somewhere in the system
- Diverter valve seized — hot water but no heating
- Annual service due to keep the Vaillant Advance warranty valid
- Considering an upgrade from an old ecoTEC to the new ecoTEC plus
- New install — combi swap, system boiler, or full conversion

Frequently asked
Questions we get asked about vaillant boilers in aberdeen.
- How long is a Vaillant warranty?
- Standard Vaillant warranties run 5 to 7 years, extending to 10 years on the ecoTEC plus when installed by a Vaillant Advance member and serviced annually. The condensate trap and a couple of consumable parts are usually outside the warranty cover.
- What does F75 mean on a Vaillant?
- F75 is a pump or pressure sensor fault. The boiler thinks the system has the wrong pressure when the pump runs. Sometimes it's a genuine sensor failure, sometimes it's air trapped in the system, sometimes it's the pump itself. We diagnose properly on site.
- Why is my Vaillant losing pressure?
- Either a system leak (anywhere from a radiator to the pipework), a failed expansion vessel, or a worn-out filling loop. We'll check the system pressure over time, look for visible leaks and check the expansion vessel charge — usually identifies the cause in one visit.
- How much is a new Vaillant ecoTEC plus in Aberdeen?
- Ring us with the kW rating you need and your installation specifics. We'll quote everything in writing — boiler, flue, controls, system flush, removal of the old unit and labour — so there are no surprises.
- Do you fit Vaillant smart controls (vSMART)?
- Yes — vSMART or vrnetDIALOG depending on the model. Compatible with most modern Vaillants. We supply, wire, configure and walk you through the app before we leave.
- Is Vaillant or Worcester the better choice?
- Both are excellent. Worcester edges Vaillant on UK installer support and the 12-year tier; Vaillant edges Worcester on long-term reliability and efficiency in our experience. We'll recommend based on your property and budget, not commission.
