Vaillant Boiler Controls

Choosing your Vaillant boiler plus control
Boiler Plus is government legislation that aims to improve the way homes in the UK use energy by increasing the efficiency of their heating systems. As of April 2018, all boilers must now have a minimum ErP efficiency of 92% and all installations must have time and temperature controls fitted.
That’s why as standard, all of our Vaillant boiler installations come with bespoke temperature controls fitted.

Vaillant Senso Controls

Specifically designed for your Vaillant system, this filter acts as a barrier, capturing dirt and debris before they can cause damage and affect water circulation. Installing this simple yet effective filter guarantees continuous and efficient water flow throughout your heating system. The result?
