Home CO2 Heat Pump for Space and Hot-Water Heating by DENSO/Vattenfall

Case Study - Heat Pumps / Domestic

This CO2 HP can replace a conventional gas boiler for space heating and hot-water generation without costly retrofitting. The high-temperature heat pump system has been specially developed for existing single-family homes that are heated by gas boilers with radiators, and are moderately insulated.
In addition to the heat pump, it employs a “stratified buffer” that acts as a battery, “temporarily doubling the heating capacity.” Water leaves the heat pump at temperatures higher than 65°C (149°F) and enters the buffer which produces temperatures up to 85°C (185°F).

The heat pump will first be rolled out in the Netherlands in mid-2022, with the aim of introducing it to countries with a need for this type of solution in the future, including the U.K.

Temperatures: 70-90°C, power 6 kW base, 11 kW peak.
