European officials focus on fire safety issues related to R290 refrigerants in heat pump systems.

In the realm of sustainable home heating, a significant shift is underway. Major players such as AIRA, Panasonic, and Ideal Heating are transitioning from F-gas refrigerant-powered heat pumps to R290, a refrigerant with lower environmental impact and higher energy efficiency.

This shift is not happening in a vacuum. The industry is focusing on balancing the advantages of R290 with safety measures to ensure its efficient and secure use in homes. Leading this charge is the SkillSafe project, backed by €1.3m and spearheaded by Daikin Europe. The project aims to develop risk assessments and pilot guidelines in five countries, with the ultimate goal of improving safety standards for R290 heat pumps during installation, use, and disposal.

David Hilton, an authoritative figure in sustainable building and energy efficiency, is a key voice in this transition. With extensive knowledge in building fabrics, heat recovery ventilation, renewables, and conventional heating systems, Hilton serves as a distinguished speaker at the Homebuilding & Renovating Show. He reassures that the chances of ignition with R290 heat pumps are low, provided leaks don't occur near drains.

Hilton, who holds membership in the Gas Safe Register and has a Masters degree in Sustainable Architecture, believes that while R290 is flammable, it is not necessarily a problem when used in a contained environment. He emphasises that if leaks don't occur near drains, the risks associated with R290 heat pumps are minimal.

The European Heat Pump Association supports the EU's SkillSafe project, recognising its importance in creating guidelines for installers and consumers handling the flammable refrigerant R290. The project's ultimate goal is to ensure the safe and efficient use of R290 in air source heat pumps, addressing concerns about its flammability, particularly in residential properties.

Propane in the form of R290 has no natural smell, and the typical gas smell is added as an impurity. However, this can interfere with the refrigerant's function, making it crucial to handle R290 with care. The SkillSafe project aims to address these concerns by developing guidelines and training for installers and end-users.

David Hilton, with over 35 years of expertise as a seasoned renewables and ventilation installer, is recognised for his contributions to Homebuilding and Renovating magazine. His reassuring voice and extensive knowledge make him an invaluable asset in navigating this transition towards more sustainable and efficient home heating solutions.
