In the pursuit of joining the green revolution, a village resident faced a challenging and costly journey to install a heat pump in his English countryside home. Lord Adair Turner, a prominent figure in the clean energy movement, recognizes the difficulty in enabling millions of households to make this transition. Governments across Europe are grappling with the same obstacles of limited supply and high costs as they strive to eliminate fossil fuel heating systems.
Heat pumps are considered a leading alternative due to their efficiency in converting electricity into heat. By drawing warmth from the outside air or ground, they can produce more than three times the heat energy for every unit of electricity consumed. However, the widespread adoption of these pumps is hindered by the complexity and expense of switching heating systems.
Attempts by governments to enforce the necessary change have not met with success. Germany, for example, faced a backlash when a proposal to ban gas and oil boilers resulted in opposition and a political crisis. Only 6% of heating systems in Germany are heat pumps, with the majority of households relying on oil or gas boilers. Berlin aims to ensure that newly installed systems derive at least 65% of their power from renewables starting next year.
Countries with clearer financial incentives have achieved greater progress. The gas price crisis in Europe has driven a significant surge in heat pump sales, with a 39% increase in 2022. Nearly 20 million heat pumps are now installed in Europe and the UK. Success rates vary among nations depending on factors such as energy costs, existing heating infrastructure, and governmental incentives.
Norway, despite its wealth as an oil and gas producer, began shifting away from oil-fired heating after the 1973 oil shock. The country has even banned oil and paraffin for heating purposes. With abundant hydropower resources, Norway has embraced direct electric heating and heat pumps. Climbing electricity prices have further motivated adoption.
Poland also experienced a doubling of installed heat pumps last year. The implementation of clean air regulations and subsidies covering up to 90% of the cost of boiler replacements has contributed to this success. Solidarity with Ukraine, driven by the desire to avoid supporting Russia, has also played a role.
Italy has seen significant heat pump sales due to tax credits covering up to 110% of the cost of energy efficiency upgrades. The tax incentives propelled Italy to the seventh-highest sales volume in Europe last year. Users have reported greater comfort, although the relatively high cost of electricity in Italy limits potential savings.
To meet the rising demand, companies are scaling up production. Chinese manufacturer Midea plans to establish a heat pump factory in Italy as part of its expansion in Europe. German company Vaillant has committed nearly €2 billion to enhance its business, including a new factory in Spain. Bosch and US-based Carrier Global are also investing substantial amounts to expand their production capacity.
However, the UK lags behind in heat pump adoption. The higher cost of electricity compared to gas prices, along with policy costs affecting electricity prices, has resulted in low interest. The UK had the lowest heat pump sales per household in Europe last year.
While upfront costs vary, estimates suggest that purchasing and installing an air-source heat pump in the UK can range from £7,000 to £15,000. Efforts are being made to reduce costs, but experts believe there may be limitations to achieving significant economies of scale in manufacturing. Instead, streamlining the installation process could offer potential savings.
Despite potential cost reductions, bureaucratic obstacles in the UK remain. Homeowners in England require planning permission to install a heat pump less than one meter from their property boundary. These barriers deter many from pursuing heat pump installations.
In his efforts to promote adoption, Lord Adair Turner discovered that rising demand for heat pumps does not necessarily result in increased employment opportunities for technicians due to a lack of apprenticeships and skilled workers. Nevertheless, Turner is satisfied with the performance of his heat pump and dismisses the notion that a perfectly insulated house is necessary for a heat pump to function effectively. Adjustments such as increasing radiator size and wearing warmer clothing during cold snaps have proven sufficient.
The UK, like other countries, faces challenges in transitioning to heat pumps as a clean energy solution. However, with the right investments in infrastructure, financial incentives, and policy adjustments, it is possible to overcome these obstacles and accelerate the adoption of heat pumps in homes and businesses.
