Project Background
Heat pumps stand as a pivotal solution in the transition to fossil fuel free heating technologies. Yet, their true potential in offering a greenhouse gas-neutral solution for space heating and hot water hinges on significantly reducing both direct and indirect emissions. Addressing this challenge, HEAT, in collaboration with Deutsche Umwelthilfe (DUH), was commissioned by the German Environment Agency to craft guidelines aimed at minimizing the greenhouse gas emissions of domestic heat pumps. Key strategies include transitioning to non-fluorinated refrigerants and enhancing the energy efficiency of these systems. HEAT’s evaluation of heat pumps’ environmental impacts has been instrumental in shaping the criteria for the Blue Angel eco-label criteria.
Project Activities
Project activities encompassed a thorough analysis of the market and the latest advancements in heat pump technology, alongside a detailed life cycle assessment. The proposed criteria, aiming to redefine industry standards, promote the use of halogen-free refrigerants, superior energy efficiency, reduced noise levels, a display for monitoring efficiency, and a suite of measures to guarantee their long-term performance, including the availability of spare parts and energy-efficient configurations.
Engaging with the industry, HEAT and DUH facilitated a dialogue through individual interviews and an interactive online workshop in March 2022, gathering invaluable insights from manufacturers and stakeholders. These collaborative efforts aim to ensure that heat pumps not only significantly lower greenhouse gas emissions but also mitigate other environmental impacts.
Following the results of this project, the German Environment Agency, alongside RAL GmbH, is now propelling the formal adoption of the Blue Angel eco-label for domestic heat pumps. This marks a significant milestone in aligning heating technologies with global efforts to limit global warming.
