What is district heating and the different types?

Projects

COOL DH

COOL DH is an abbreviation of Cool ways of using low grade Heat Sources from Cooling and Surplus Heat for heating of Energy Efficient Buildings with new Low Temperature District Heating (LTDH) Solutions. The COOL DH project innovates, demonstrates, evaluates, and disseminates technological solutions needed to exploit and utilise sources of very low-grade surplus heat for heating of energy efficient buildings via Low Temperature District Heating (LTDH). The project shows how the transition of District Heating (DH) systems towards LTDH can make these more resource efficient and more energy efficient.

IEA-DHC Annes TS2

Implementation of Low Temperature District Heating Systems. Annex TS2 is a project aiming at facilitating the implementation of 4th generation Dis- trict Heating (4GDH). It is a continuation of the first task shared annex on 4GDH which aimed at collecting what is known about 4GDH in one report (Annex TS1).
