Electrification of Heat – 2010s detached house heat pump installation

Stephen, Dina and Layla live in a 2010s four-bedroom detached house in suburban Edinburgh, Scotland.

Stephen and Dina’s fully insulated property was built in the last decade, equipped with a modern gas boiler. However, as both of them are passionate about the environment, so it was important to them to reduce their carbon footprint. But they had real concerns about whether or not a heat pump would heat their house sufficiently.

The Electrification of Heat (EoH) demonstration project, funded by the Department for Business, Energy and Industrial Strategy (BEIS), is seeking to better understand the technical and practical feasibility of a large-scale rollout of heat pumps into existing British homes.

The Challenge

The recruitment and installation phase of the EoH project ran from July 2020 through to October 2021, and despite the challenges of the Covid-19 pandemic, 742 heat pumps were installed into a broad spectrum of housing types and socio-economic groups, that reflects a representative sample of households across Great Britain.

The range of different heat pumps installed, included:

  • Low-temperature and high-temperature air source heat pumps
  • Ground source heat pumps
  • Hybrid heat pumps incorporated with a gas boiler
  • Some additional technologies, such as heat batteries were incorporated.

Householders were asked to reflect on their first hand experiences of taking part in the programme, including disruption during the installation work, thoughts on the noise and aesthetics of the technology and the outcomes for warmth and comfort.

The Solution

After carrying out a full inspection of the property, the installers suggested an air source heat pump which was installed in the garden, with a new hot water tank moved from an upstairs cupboard to the garage, where the gas boiler was previously located – freeing up storage in the house.

The Outcome

Stephen feels glad that they have done something positive for the environment and that young daughter, Layla will grow up with a heat pump as the norm. The couple also believe that having a renewable heating technology installed in their house will increase the value of the property when they
would like to sell it.

Stephen and Dina have not received any bills yet; however, they expect their heating bills to increase
slightly as electricity is more expensive than natural gas and their old gas boiler was highly efficient.

Despite initial concerns Stephen is very happy with the performance of the heat pump, as the house is as warm as it was before and the hot water pressure is now better.
