Viessmann engineers in Leamington Spa

Working on Viessmann boilers every week

Viessmann build quality is a step up, and the stainless steel heat exchanger in the Vitodens range is the reason many of them are still going strong long after cheaper appliances have been scrapped. Serving Leamington Spa and the surrounding Warwickshire area.

They do still need annual servicing, and the electronics and sensing side benefits from an engineer who knows the range. We work on the 050-W, 100-W, 111-W storage combi and the 200-W.

Where a Vitodens throws an F2 overheat or a sensor fault, the answer is usually circulation or a thermistor rather than the heat exchanger itself, and we test before we condemn anything expensive.

New Vitodens installations are registered with Viessmann on your behalf so the full manufacturer warranty applies from day one.

Common signs to look out for

  • Vitodens repairs and fault diagnosis
  • Stainless heat exchanger inspection and cleaning
  • Annual servicing to Viessmann's schedule
  • New Vitodens installation and registration
  • Sensor, pump and circulation fault finding
  • Vitodens 111-W storage combi expertise

Servicing and warranty

Keeping your Viessmann warranty valid

Viessmann 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 Viessmann service with the CP12 gas safety check on a single visit and email both documents the same day.
