About the event

The Role of Heat Pumps in Decarbonisation online conference was held on the 28th of October 2021 hosted by EECA and Massey University. It was aimed at anyone with an interest in using vapour compression technologies (such as high-temperature heat pumps) to decarbonise their process or space heating requirements.

It covered both industrial and residential heat pump technologies and includes space heating and water heating applications.

Presentations covered all elements of the decarbonisation HTHP journey from inception through to installation – what to know, what to avoid and what to expect.
