Viessmann
Although I am more than happy to install, maintain or repair any boiler of your choice, PR Plumbing and Heating recommends Viessmann.
Viessmann supplies high quality heating systems and components with German engineering and a strong approach to green efficiencies.
5 year guarantee
The standard warranty of 3 years is increased to an amazing 5 years for all Viessmann boilers fitted by installers who have successfully completed a relevant Viessmann training course.
This guarantee is a genuine, no-strings attached warranty – with no hidden costs.
I believe it is the best warranty in the industry and it demonstrates the confidence in the quality of the Viessmann Vitodens range of boilers.
Inox-Radial Heat Exchanger
All Vitodens domestic boilers, feature Viessmann's unique stainless steel heat exchanger, designed for long-term reliability, high performance and self-cleaning.
This component is so reliable that it is guaranteed for 10 years against corrosion.
Further efficiencies
The Lambda Pro combustion controller works alongside the burner to constantly monitor the air to gas ratio.
Instead of the gas remaining fixed from commissioning, the mix is automatically adjusted as required to maintain the correct ratio (in a similar way to fuel management systems in car engines).
Lamba pro works efficiently irrespective of the quality of the gas – a factor which is becoming more and more important as international gas supplies become less reliable and gas of different qualities are imported from other countries.
A boiler with Lamba Pro Control will not lose efficiency even if it is burning imported gas which may be of a poorer quality.
Greener emissions
Developed by Viessmann, the Matrix burner distributes heat cleanly and efficiently. Nitrogen oxide is kept to a minimum as the gas burns almost without flame, thanks to the complete pre-mixing of air and gas.

The extremely low NOx and CO emissions meet or exceed all international clean air regulations and guidelines.
Demand is optimised by modulation and maximum efficiency levels are achieved.
