The Viessmann brand had an overall score of 83%. This we think you will agree is an excellent score by the trusted ‘Which’ organisation.

Viessmann got maximum marks for:

Although Viessmann boilers are clearly amongst the best in the world they do have the potential as with all things to occasionally develop a fault requiring a qualified engineer. However, by having your boiler serviced yearly will help to minimise any issues and also help to have minor issues corrected before it can become an expensive issue.

In order to aid your engineer to deal with issues that can potentially arise the Viessmann boilers have the ability to display a fault code. This code aids your engineers to get to the root of the problem quickly reducing cost. We do however recommend having any fault dealt with swiftly.

Viessmann Boiler Controls

There are a very good range of boiler controls and heating controls available for Viessmann boilers. These controllers will need to be matched to the Viessmann boiler you are intending to put in. These controls will aid you in manging temperature, timings and getting energy saving. The range of controllers include:

  • Smart intelligent controls – use your smart phone to change your hot water and heating
  • Weather compensating controls
  • Wireless room thermostats
  • Wireless remote controls

When you have the right controls for your boiler you can save energy and therefore money on your bills for fuel.
