When replacing a old heating boiler with a modern condensing boiler, are there regulations?

If an older boiler is being replaced with a new condensing boiler then Building Regulations suggest that the rest of the system is upgraded to ensure that:

  1. The storage cylinder complies with BS 1566:2002 (mainly the level of insulation – the existing cylinder may already comply)
  2. The system controls are also upgraded to include time and temperature control (e.g. a programmable room thermostat if one is not already in place).
  3. The system is cleaned and flushed prior to installation of the new boiler – in accordance with the manufacturers instructions

Given that the whole system will be shut down it would be worthwhile considering the installation of individual thermostatic radiator valves (TRVs) in all areas except where the main thermostat is located. These need not be expensive and will give greater flexibility of room temperature control (bedrooms can be set to be cooler than main living areas) and will save energy – and money.
