The 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 significant carbon savings, the heat pump maintained a comfortable indoor temperature above 20°C all year round, with a Coefficient of Performance (COP) consistently exceeding 4.2, highlighting its high energy efficiency.

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 efficiency, cost-effectiveness, and environmental impact.

Mark McManus, Stiebel Eltron UK managing director, said: “There is a growing onus being placed on technologies which will significantly 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 confidence that it will deliver huge carbon reductions, maintain a constant and comfortable indoor temperature, and perform efficiently 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.”
