Boiler Plus aims to improve the energy efficiency of homes in the UK by increasing the efficiency of their heating systems. From 6 April 2018, all boilers must have a minimum ErP efficiency of 92% and all installations must have time and temperature controls fitted. Combi boilers require one of four additional requirements to comply: select 3.....

• •load compensation – this intelligent communication modulates the flow temperature from the boiler, based on the actual room temperature

• •condensate recycling: to neutralize otherwise waste condensate water, and recycle it for use in non potable water needs.

• •smart control – a control allowing full automation and enhanced efficiency

• •FGHR (flue gas heat recovery) – a way to redirect otherwise lost flue gases to heat water in the boiler.

• •CHR (Condensate heat recovery) – a way to redirect otherwise lost heat from condensate waste water to heat water in the boiler.

Which document covers condensate disposal?

• Approved document A

• Part P

• BS 1212 part 1

• BS 8000 part 13

• BS 6798
