Heat Pumps

Overview

Domestic Heat Pumps have a strategic role in reducing greenhouse gas emissions and the energy consumed from heating houses.  ENA and its members are investing in smart networks to ensure the networks can safely and reliably support the range of electricity demand and generation, including electricity demand and harmonic issues from heat pumps.  

The Renewable Heat Incentive and the Green Deal shall incentivise customers to look at greener renewable technologies to heat their homes and buildings, with Domestic Heat Pumps being at the forefront along with other techniques including insulation and Photo Voltaic (Solar Panels).

ENA Heat Pumps Working Group

This working group concentrated on connection processes and the evaluation of  technical characteristics for Domestic Heat Pumps.  The working group has now introduced connection notification processes via discussions with DECC, Ofgem and MCS/Gemserve. 

The working group has now met the Terms of Reference. ENA will now progress with the Low Carbon Technologies working group also covering Electric Vehicles, established to address high level technical, regulatory and standards issues as GB moves toward a low carbon economy.
