Manufacturer hopes first year review of mandatory regulations will back expansion of standards beyond gas appliances to create a ‘Heating Plus’ concept
Vaillant has said there is much further to go in order to fine tune the Boiler Plus efficiency standards introduced last year.
The appliance manufacturer has joined a number of other gas heating specialists in calling for a range of amendments to the standards that have been a mandatory part of Building Regulations since April 6, 2018.
Mark Wilkins, head of training and external affairs at Valliant, said that an upcoming first year of the review was the perfect time to rethink how the standards can better ensure more efficient gas heating.
Mr Wilkins said he hoped government would review measures to ensure better protection of heating systems and push a focus to ensure best practice is met in the installation process, such as by hydraulic balancing.
He said, “This is something Vaillant whole-heartedly supports, after all, the UK would not be the first nation to mandate hydraulic balancing, with Germany making it a legal requirement several years ago.
“Whether the balancing itself becomes a requirement, or greater emphasis is placed on awareness, this is certainly worth consideration when it comes to reviewing improvements to Boiler Plus.”
An additional focus to be considered in expanding Boiler Plus was adding measures to address water quality in heating systems, Mr Wilkins argued.
He added that a failure to ensure clean water within a system would limit performance in even the most efficient boiler designs presently on the market, highlighting a need for revisions to the Boiler Plus legislation to account for system debris.
Mr Wilkins also backed calls for the existing Boiler Plus requirements that demand use of additional efficiency controls to be expanded beyond combi boilers and to apply to all heating systems regardless of the heat generator.
He said, “As it stands, Boiler Plus only applies to combi boiler installations. Obviously, this is a logical place to start, but the reality is that this misses around 25 per of the market.”
“Whilst it’s good to see a greater emphasis on the efficiency of combis, we would like to see the review examine how Boiler Plus could be applied to system and open vent boilers, along with heat pumps and other heating technologies – essentially evolving Boiler Plus to become ‘Heating Plus’.”
Boiler Plus came into effect on April 6, 2018, as part of UK Building Regulations. Key requirements of the standards include requiring any new heating appliances fitted in homes across England to have a minimum performance standard for seasonal space heating of at least 92 per cent based on the European Energy Related Products (ErP) Directive. At least one form of additional control or efficiency measure from a set list of technologies must also be included in an appliance.
