Energy: Housing

Volume 501: debated on Wednesday 2 December 2009

To ask the Secretary of State for Energy and Climate Change whether he has made an estimate of the energy efficiency savings that would accrue from the application of heating system water treatment cleaners and inhibitors in homes. (302111)

Heating system efficiency is determined by the combination of its main components such as the boiler and radiators. Therefore, adding water treatment cleaner or inhibitors does not increase the overall efficiency.

The application of water treatment cleaners and inhibitors is regarded as good practice within the heating installation industry to ensure the efficiency of the system is maintained over its lifetime, however, we do not hold any data to verify this assertion.
