New photographs illustrate the heating, and cooling, potential of heat pumps in the home

Climate Visuals, in partnership with Nesta, have today launched the latest images as part of our Picturing Life With a Heat Pump series – free for non-profit, editorial and educational use.

The photographs, taken in London by photographer Harry Mitchell, highlight the potential benefits of retrofitting a heat pump to a Victorian-era home;  much cheaper heating costs and effective cooling during periods of extreme heat.

Artem installed a heat pump in his pre-1920s home in East London as part of a whole-home retrofit and extension. The heat pump delivers heat across the house, both via wet underfloor heating in the kitchen extension and via new radiators throughout the rest of the rooms.

Since installation, he’s found his energy costs are much lower than with their previous gas boiler, with the system humming along to keep the whole house at a consistent 21 degrees.

Artem has also upgraded the system to include cooling capability, providing welcome respite and comfort during periods of hot weather. During the recent spell of extreme heat in the UK, this technology kept room temperatures in Artem’s house to around 24 degrees – despite outside temperatures hitting 35 degrees and higher.

These photographs highlight two major benefits being felt by heat pump users across the country already – cheaper energy bills and effective heating and cooling. As the UK feels the effect of our changing climate, adapting to extreme weather events, such as periods of extreme heat, is an ever growing concern. Artem’s experience, visualised through these new photographs, shows how retrofitting a heat pump can be an effective way to adapt to these realities whilst decarbonising domestic heating and reducing energy costs.

These latest photographs are part of a growing resource, produced by Climate Visuals and Nesta, of compelling, engaging and accessible images of heat pumps across the UK – freely available for non-profit, editorial and educational use.

All too often, photographs of heat pumps show the object but don’t tell the story. They depict a box at the side of a building, often with awkwardly posed models standing beside it. They don’t show the real world potential of heat pumps that audiences can relate to and see themselves as a part of, or the diversity of installers and users. These new images highlight the real lives that heat pumps are a part of now, helping to normalise the technology and demonstrate the benefits being felt by the households using them across different houses and lifestyles around the country.
