8,807 expressions of interest from households were received, who cited:

▶️Sustainability and low carbon heating (78%)
▶️Interest in new technology (63%)
▶️Free heat pump installation (53%)

As reasons for wanting to participate.

2/12

The project installed 742 heat pumps:

▶️ 307 - Low Temp Air Source Heat Pumps
▶️ 244 - High Temp Air Source Heat Pumps
▶️ 38 - Ground Source Heat Pumps
▶️ 153 - Hybrid Heat Pumps

Heat pumps were installed in a representative sample of British housing types.

3/12

Energy efficiency upgrades were only needed for 15% of properties where a heat pump was installed – in most cases this was loft insulation.

4/12

Homes across England & Scotland were involved in the trial: SE England, SE Scotland & Newcastle.

Anna from #Newcastle took part in the project and recently replaced her “clunky” gas boiler with an air source heat pump.

“Generally, it is quite quiet…it heats constantly and…never gets uncomfortable”.

6/12

John from Crieff in #Scotland lives in a detached 1980s house and chose to replace his gas boiler with an air source heat pump.

“Noise is the most impressive thing, there isn’t any…it’s all very laid back and quiet.”

Listen to what John said:

The main barriers to installation were:

1)Practical – external or internal space constraints
2)Technical – heating capacity constraints
3)Economic – cost of upgrades required
4)Consumer – installation challenges

8/12

The EoH project found that the main non-technical barrier to a heat pump installation was disruption. Individuals were put off by the potential disruption of the installation work. 47% of participants who declined a heat pump cited this as their main concern.

9/12

📚The data points to customers needing:

▶️Early engagement
▶️Digestible facts & up-front property assumptions
▶️Dedicated customer support

10/12

📚The installation supply chain requires:

▶️Better training & guidance
▶️A review of design & installation requirements & guidance
▶️A review & enhancement of the installer certification process

Chief Executive @guynewey, said:

“To reach 600,000 heat pump installations per year by 2028, we need to innovate to make switching to a heat pump a smooth process; to drive down installation costs; and to provide a better heating experience."
