There are more than 30 million homes in the UK and, together, they are responsible for around a fifth of all the country’s emissions, with the majority – around three quarters –generated by home heating. This makes the decarbonisation of homes key to overarching ambitions of achieving net-zero by 2050.
This places installers at the heart of activity to curb emissions and improve the efficiency of homes – both through the adoption of low- carbon systems and innovative plumbing and heating technologies.
Here, we will consider the scale of the challenge that lies ahead and the role of plumbing and heating professionals in moving the UK towards a greener future.
Why the answers lie in retrofitting and renovation
With an average of 170,000 new homes being built each year in the UK, the reality is that the majority of the homes people will live in by 2050 are already built. With millions of these properties already falling behind in terms of energy efficiency, the focus must be on retrofit and renovation to bring them up to standard.
Millions of British homes currently do not meet the requirements for Energy Performance Certification ‘C’. The impact of this rating is two-fold. Firstly, occupants of under-performing buildings may face higher energy bills alongside reduced levels of comfort. Secondly, to compensate for a property’s heat loss, heating systems will likely be working harder and having a greater negative impact on the environment.
In practice, ensuring existing homes meet EPC ‘C’ standards is essential for the UK to achieve its net zero ambitions. To achieve this, the renovation of these properties and the retrofitting of effective plumbing and heating systems – from underfloor heating through to heat pumps – to improve efficiency and reduce heat loss, will put the UK on a more sustainable footing.
The role of installers and the solutions facilitating retrofits
To make the vision of a more sustainable future a reality, installers will play a critical role. Working directly with property owners, plumbing and heating engineers are the experts on the ground, assessing properties to identify the most suitable solutions, and installing them correctly to deliver the greatest impact.
With millions of homes across the country in need of energy efficiency upgrades, tried, tested, and trusted solutions will be used heavily to unlock the best results. This approach allows homes to benefit from proven systems, minimising the disruption of adoption while delivering long-term results.
Underfloor heating (UFH) is one solution that can be installed to improve efficiency and comfort within a property. Compatible with new and old heat sources, UFH operates effectively at much lower temperatures than traditional radiator systems to reduce energy demands while sufficiently heating a home.
Its positioning beneath floors also creates a much larger surface area, enabling UFH to heat spaces quickly and more effectively, improving comfort and efficiency.
For renovation projects, low-profile UFH systems are a proven solution, enabling installation over existing subfloor structures. For screeded floor applications, castellated panels support easy installation, whereas for timber floors, foil and mesh panels can be used to run pipes efficiently. These options equip installers with the systems and versatility to upgrade home heating systems and unlock greater levels of efficiency.
Aside from retrofitting sustainable heating systems, installers can also use pipes and fittings that contribute to greater levels of system efficiency. Plastic solutions can strengthen plumbing and heating systems to unlock greater performance, while fewer connections reduce the potential for problems such as leaks – which can compromise overall efficiency. Innovations such as push-fit technology, found in RWC’s JG Speedfit range, can also reduce the complexity of upgrading systems, simplifying jobs for installers.
The future of home heating
While installing more sustainable technologies will move homes towards a greener future, it is important to keep in mind what the future of home heating could look like. Manufacturers will lead the way through product innovation to ensure that systems and solutions continue to comply as the country’s infrastructure changes.
