All of their current gas boilers achieve an A rating for heat on the Energy-related Products (ErP) directive, with many models also scoring an A for hot water production.
The Vitodens range, including popular models like the 100-W and 200-W, boasts efficiency ratings of up to 98% under the SEDBUK 2009 regulations. This exceptionally high efficiency is achieved through advanced technologies such as:
- Inox-Radial heat exchanger made of stainless steel for optimal heat transfer

- Modulating burners that adjust output to match demand
- Weather compensation controls that optimize boiler performance based on outdoor temperature
For instance, the Vitodens 200-W can achieve an impressive 98% efficiency rating, meaning that 98% of the fuel used is converted into heat for your home, placing it among the most efficient boilers available in the UK market.
