alternative, more energy efficient ways to heat our homes and buildings that also help to keep heating prices down. To achieve that, district heating systems need to be included in any thoughtful reinvention of the UK’s heating infrastructure.

heating methods used today —such as gas boilers. Their impact is multiplied many times when the district heating system incorporates high-efficiency electric heat pumps using ready-now, low-global-warming-potential (GWP) hydrofluoroolefin (HFO) refrigerants such as Honeywell’s Solstice® ze (R-1234ze), which offer benefits for a number of heating and cooling applications.


As a 150-year-old method for heating, district heating systems offer a paradigm-breaking alternative to the conventional “one building, one boiler” approach that is common throughout homes and businesses in the UK and
