The new 'Boiler Plus' legislation is a part of the Government’s ‘Heat in Buildings’ programme which aims to maximise energy efficiency. The introduction of Boiler Plus is the first major piece of legislation since the UK became the first country to go “all-condensing” in 2005.
From 6th April 2018, all new boiler installs must have time and temperature controls fitted and achieve a minimum ERP efficiency of 92%. Any installer that fails to comply with Boiler Plus could potentially be prosecuted by Building Control. If a homeowner knowingly allows non-compliant work, they could also face prosecution and a fine of up to £5000. The new standards only apply when a consumer replaces their boiler.
Combi boilers will require one of four additional components to be fitted. These will need to be suited to each individual properties requirements, as what works for one install might not be suitable for another. The measures available are:
- Smart control - Instead of basic on/off and temperature control a smart thermostat allows you manage every minute of your home’s heating schedule, usually from a smartphone, tablet or computer. Some Smart controls will adjust the temperature/schedule automatically based on inputs from other Smart devices.
- Passive Flue Gas Heat Recovery Device (PFGHRD) - A heat exchanger is fitted around the flue to heat up mains cold water that is fed into it, the heated water is then either stored for later use, or used as pre-heated incoming water.
- Load compensation - This feature adjusts the temperature of the water being fed to your radiators based on the temperature of your home. On colder days, radiators will be supplied with warmer water.
- Weather compensation - This feature adjusts the temperature of the water being fed to your radiators based on the outside temperature. On colder days, radiators will be supplied with warmer water.
