Viessmann Boilers in Kingston & KT/TW

Viessmann is a premium German boiler manufacturer whose Vitodens range is regarded as one of the most efficient and best-built boilers on the UK market. We install, repair and service Viessmann boilers across Kingston, Richmond, Twickenham and the wider KT/TW postcodes.

The stainless steel Inox-Radial heat exchanger is Viessmann's signature — it's built to last decades and is one of the reasons Vitodens warranties run up to 12 years.

Viessmann models we install

Vitodens 050-W — a cost-competitive combi that still uses the Inox-Radial stainless steel heat exchanger. Great value.

Vitodens 100-W — the core Viessmann combi, popular in mid-to-larger family homes across Esher, Cobham and Richmond.

Vitodens 200-W — flagship combi and system boiler with weather-compensating controls and up to 12-year warranty.

Vitodens 111-W storage combi — combines a small cylinder in the boiler for higher hot-water flow rates in tight installations.

Viessmann repair — common faults

F.2 safety chain fault — often a limit thermostat or overheat sensor.

F.4 no flame signal — typically a spark electrode or ignition unit issue.

F.5 fan fault — a common failure point on older Vitodens 100 units.

Low pressure — we repressurise, check the expansion vessel and locate any leak on the system.

Warranty and Trained Installer status

Viessmann's up-to-12-year warranty is available when installed by a Viessmann Trained Installer. We complete the required commissioning and register the warranty on your behalf.

Annual servicing with genuine Viessmann parts keeps the extended warranty valid.

Frequently asked questions

Is Viessmann better than Worcester Bosch or Vaillant?

Viessmann's build quality and heat exchanger are class-leading. Worcester and Vaillant have wider UK parts networks. For a long-term install, Viessmann is a strong choice.

How long is the Viessmann warranty?

Up to 12 years on Vitodens 100 and 200 when installed by a Trained Installer and serviced annually.

Are Viessmann parts easy to get in the UK?

Yes — Viessmann has strong UK parts availability. Most common service parts are on our van; anything specialist is typically next-day.
