Summary

A new district heating system in Rørvig, Denmark – which is powered by Danish OEM Advansor’s SteelXL CO2 (R744)-based heat pump – will help reduce residents’ energy bills by up to 50% and CO2 emissions by up to 70%, according to a case study from Casper Christiansen, Business Development Manager for Heat Pumps at Advansor, and Martin Sønderby, Sales Manager at Aktive Energi Anlæg (AEA), the project’s designer and contractor.

The case study was presented by Christiansen and Sønderby during an HVAC and heat pumps session at the ATMOsphere (ATMO) Europe Summit on natural refrigerants. The conference took place November 15–16 in Brussels and was organized by ATMOsphere, publisher of R744.com.

Advansor’s air-to-water heat pump has a heating capacity of 1.5MW (426.5TR) and will provide around 244 households in Rørvig with heat for hot water production and space heating. Previously, most residents used oil burners or electric heating, explained Sønderby.

By transitioning from gas heating to a CO2 heat pump, consumers will save around €2,000 (US$2,050) a year in heating costs, he added.

According to Christiansen, the adoption of the district heating system in Rørvig will save 300,000m3 (10.6 million ft3) of gas each year, which will avoid the emission of 470 metric tons of CO2e annually.

“Not only are there economic benefits in choosing a CO2 heat pump, but it’s also a sustainable and environmentally-friendly solution,” he added.
