New Heat Pump Concept for Temperature Flexible Low-Temperature Operation Used for District Heating

---

This article describes the new approach to low-temperature district heating using a new type of heat
interphase unit equipped with micro-heat pumps called Flex-Booster. The system will be demonstrated in a network with about 300 consumers. The network will use plastic pipes and a heat supply from
a heat pump, partly powered by solar electricity. Concept and technology are described, as well as
perspective on market potential. The special focus is on the benefits and problems solved with the
Flex-Booster concept vs using traditional district heating systems.
