Abstract Low-temperature thermal networks enable simultaneous heating and cooling of buildings and reduce CO 2 emissions by substituting fossil fuels by environmental heat sources. In this work, we compare two different network topologies, the traditional low-temperature network (TLTN) and the new reservoir low-temperature network (RLTN). We show that the volume flow in the RLTN can be adjusted to increase the efficiency of heat pumps and to reduce hydraulic power losses in the supply lines without compromising heat demands.
