HEAT PUMPS
networks in the UK, with nearly 500,000 connections. Together, they meet about 2% of the UK’s space heating requirements, and that number could increase to 15%–18% by 2050. Honeywell supports ambitious investment and incentive programs to grow the number of district heating networks, which will go a long way to helping Britain achieve its net-zero ambitions.
Taking district heating to new heights reduces costs by heating water at a central location and distributing it to homes and buildings through a series of insulated pipes. be compounded by using electricity instead of natural gas to heat the water.
5kW of heat for every 1kW of electricity. A new only, producing less than 1kW of heat per With that in mind, the government is
providing incentives to homeowners to help them replace their boilers with electric heat
pumps. These incentives amount to a £5,000 grant, awarded to 90,000 households over three years. This type of incentive could encourage meaningful change. There is also more that can be done to stimulate the use of electric heat pumps in district heating applications. There are already multiple examples of the successful application of this approach, including one in the London Borough of Southwark, and another in Stirling.
As if their superior performance weren’t
heat pumps are more environmentally friendly thanks in part to the use of low-global- warming-potential (GWP) refrigerants, such as Honeywell’s Solstice® ze (R-1234ze). go to an even higher level if the heat pump is powered by electricity from a renewable source, such as wind, solar, biomass or nuclear fusion. The unique nature of a heat pump also enables it to recover waste heat from supermarkets, data centres, powerplants or other industrial processes to heat the water that ultimately keeps our homes, workplaces and common spaces warm and comfortable.
Creating a virtuous cycle of positive change District heating and electric heat pumps have conventional thinking and reinvent the home and building heating system that we have relied on for generations. It’s important we continue innovating in this area if we want to reduce our dependence on fossil fuels, achieve our ambitious carbon-reduction targets and provide everyone with access to space heating that is dependable,
While initial capital outlays needed to support
they will ultimately pay for themselves many times over through reduced energy costs and quality of life improvements. Government involvement and support to make the infrastructure changes will enable large segments of the population to realise the advantages of district heating networks using electric heat pumps. Recognising the role fossil fuels will continue to play, we also need to continue down a path where more of our energy comes from renewable sources. And we need education campaigns to hasten public understanding, support and uptake for what may seem like a radical new approach to providing for a fundamental human need.
