Booster heat pumps and central heat pumps in district heating
TLDR
In this article, the authors investigated two alternatives for DHW supply: (a) DH based on central heat pump (HP) combined with a heat exchanger, and (b) a combination of DH and a small booster HP using DH water as low-temperature source for domestic hot water (DHW) production.About:
