Heat pumps emit 95% fewer emissions than gas boilers a year
A new study from Stiebel Eltron UK has found that heat pumps in a home setting emit almost 95% fewer carbon emissions than a traditional gas boiler annually.
Pawel Markowski, Senior MEP Manager at Berkeley explained the decision: “The features of the Uponor system, including the inspection window and press indicator, gave us confi dence in the reliability of the install process. Uponor MLCP was chosen over copper on this project as the fl exibility made it easier to work with in the small installation spaces in the apartments. Ultimately, it was chosen to ensure a quicker, easier and more consistent installation.” The inspection window on the S-Press PLUS makes it simple to check the pipe has been inserted to the correct depth. The unique press indicator feature consists of a specially designed foil around the sleeve to clearly show if the pressing has been completed correctly. The foil is removable as soon as the connection is safe. Reliability of testing was also an important factor on the project, as
any inadvertently unpressed connections could cause leaks that would have a serious impact. The Uponor S-Press PLUS fi ttings are designed to leak immediately and obviously during testing if it has not been pressed properly, even at a very low-pressure level. Gary Mills, MEP project manager at Malcolm Building Services, which
carried out the installation within the building commented: “The use of the system has really helped to streamline the work. This is not only due to the easy press fi tting process, but also the much longer lengths possible with the MLCP, which means fewer joints. The fact the Uni-Pipe PLUS is supplied pre-insulated further reduces the work required on site.”
In addition to its use on site, MLCP and press fi ttings were also used
for the pipework within the bathroom pods. These off site manufactured modules include all elements of the bathroom, including the fi xtures and fi nishes, and are delivered to site and simply craned into place and connected to the rest of the apartment’s pipework. Furthermore, Uponor provided full technical and product support
throughout the project. This began in the early stages with input on the design to optimise the pipework. The Uponor team also participated in regular meetings with other project stakeholders and helped to solve any issues that impacted this element of construction. To help ensure the benefi ts of the system were maximised and that
installation best practice was achieved, the company delivered training to all the installation operatives. This was followed by regular observations and checks of the installed pipework to ensure the highest level of quality was maintained. Pawel added: “The support has been outstanding throughout. The team has gone above and beyond and has always been available and proactive whenever we needed to fi nd a solution. This included working with our off -site partner to ensure correct installation practices across all elements of the project.”
T
he study, which took place over a 12-month period, found Stiebel Eltron’s WPL-A 07 Premium air-
source heat pump produced 250kgCO2e, whereas a conventional gas boiler in the same dwelling would emit over 3,500kgCO2e. The manufacturer of heat pumps
and renewable energy technologies carried out the study to showcase the value of a heat pump in reducing carbon emissions, with the research focusing on its performance in a four-bedroom home.
As well as showing signifi cant carbon
savings, the heat pump maintained a comfortable indoor temperature above 20°C all year round, with a Coeffi cient of Performance (COP) consistently exceeding 4.2, highlighting its high energy effi ciency. Meanwhile, the heat pump cost £750 a year to run, some £250 less than a traditional boiler in the same setting, with the unit’s reduced energy consumption contributing to long-term savings on utility bills. The company monitored the
performance of the heat pump using real-time reporting and data analytics via the company’s monitoring software, providing valuable insights into its effi ciency, cost-eff ectiveness, and environmental impact. Mark McManus, Stiebel Eltron
UK managing director, said: “There is a growing onus being placed on technologies which will signifi cantly reduce carbon emissions which come from homes and buildings. These results show that a heat pump does exactly that. “Consumers who are exploring the possibility of a heat pump can have confi dence that it will deliver huge carbon reductions, maintain a constant and comfortable indoor temperature, and perform effi ciently while bringing cost savings at the same time. “As the environmental benefits
become more prominent and the need for more carbon efficient homes becomes greater, demand for heat pumps is only going to increase in the years to come. We’re looking forward to meeting this demand, equipping both consumers and installers with the technology, and knowledge, to transition towards greener energy solutions.”
