Boiler Plus legislation

Boiler Plus legislation

What is the new boiler plus scheme?

From April 2018 new standards will need to be applied whenever a new boiler is installed within your home. These new standards will help homeowners improve the way they use energy in their homes by giving them a greater choice, more control and noticeable savings on the energy bills. The new minimum performance requirements for domestic gas boilers in England will be set at 92% ErP.

ERP

The boiler must have an ErP label of 92%, this will ensure the household benefits from an efficient boiler. A boiler below 92% will not comply with these new regulations even if the label is bought up to 92% using other components.

Energy saving technologies

Timers and room thermostats will be an essential requirement for all gas and oil boiler installations. When a new gas combination boiler is installed a further energy efficiency measure will be necessary to comply with the new legislation. The new requirements have been made flexible, allowing a suitable choice to be made that reflects the needs of the household. The following energy-saving technologies can be used to comply with the new legislation.

  • Weather compensation kits – These kits help measure the outside temperature and reduce the boiler water flow temperature. This will then help improve boiler efficiency, provide a consistent temperature around the house most importantly help save money on energy bills.

 

  • Heat recovery systems – Also known as mechanical ventilation heat recovery (MVHR), These systems help provide ventilation without the loss of heat or humidity. It reduces the energy needed to reach the required flow temperature. It eliminates condensation within the home which in turn helps eliminate any risk of structural and cosmetic damage and also mould. A heat recovery system can help recover up to 90% of heat being lost.

 

  • Load compensation – Load compensators automatically help control the temperature of the water going to the radiators. Temperature going to the radiators will be high if the rooms are cold but once the rooms start to warm up less heat will be required and temperature going to the radiators will be reduced. This will help reduce energy consumption and maintain a comfortable room temperature.

 

  • Smart controls featuring automation and optimisation functions – Smart controls have the potential to deliver noticeable savings on your energy bills. BEIS considers smart thermostats to be products that will let you remotely control your home temperature via a tablet, smartphone for greater control over the central heating system.

What could be the typical savings with each technology?

The BEIS document sets out a typical consumer’s costs and energy savings in the first year of operation as follows:

  Additional upfront  costs (£) Yearly bill saving (£) Payback period (years)
Learning thermostats
(specified smart control)
190 17 11
Load compensation 50 4 13
Flue gas heat recovery* 460 15 14
Weather compensation 130 4 35

BEIS also notes: “The results show that learning thermostats and load compensators pay
back within technology lifetimes (15 years), even at the higher year-one cost. For those
consumers who value lowering their upfront cost, bill savings will be significantly smaller
compared to those who seek to maximise bill savings over the longer term.


“Weather compensators and FGHR will likely not be attractive offers to the majority of
consumers due to the high upfront costs or long payback periods. For some circumstances,
however, these technologies will be beneficial, eg, households with high hot water demands
who can benefit from higher than average performance from FGHR and associated bill
savings.”

* The BEIS document estimates the upfront cost of flue gas heat recovery would fall significantly to £200 from Year 2 onwards because of mass production savings, reducing the implied payback period for consumers.

What does this mean for installers?

Installers will need to be able to offer customers advice on all of the above and be able to install them. The new standards have been set at a level that is not beyond the capabilities of installers. 

Installation man

The technologies listed are all existing technologies which installers should already be familiar with, however, those who are not so confident with the new standards should take advantage of a huge range of free training available. Installers who fail to keep up with the latest technology advancements may struggle as the market moves and if installers and homeowners do not comply to the latest regulations they will be breaking the law and could face prosecution.

Here at Graham, we have made it easier to make sure you are compliant with the new legislation when purchasing heating products. Take a look at our Boiler Plus booklet which will help find the right product for you.
