Boiler Plus
On April 6 2018, changes to technical standards under Building Regulations Approved Document L1b (also known as Boiler Plus) came into effect and apply installations in existing buildings in England only.
The main changes are:
- Seasonal space heating efficiency of the new boiler no less than ErP 92%
- Time and temperature control required for all installations
- All combi installations must also include one of the following:
- Weather compensation
- Load compensation
- Flue Gas Heat Recovery
- Smart control with automation and optimisation
Background
In 2005 Approved Document L of the Building Regulations changed to require the installation of condensing boilers. Since then, there has been very little in the way of changes to minimum standards for heating installations.
In September 2015 the EcoDesign of Energy Related Products Directive (ErP) was introduced, which takes a more holistic view of heating system efficiency by recognising the impact of controls on the overall "package” of installed components.
The Department for Business, Energy and Industrial Strategy (BEIS) launched a consultation document in December 2016, and the subsequent policy changes concerning minimum requirements when installing boilers in existing buildings were effective from 6 April 2018, in England only.
The changes are not only beneficial to efficiency and emissions but are also easily adopted, low cost and simple to factor into a boiler installation:
- Getting the best deal for consumers
- Making it easy for installers
- Attaining measured and sustainable fuel use reduction.
