A closed loop heating system (1, 34, 38) comprises at least one closed fluid circuit (14, 15), at least one thermal energy receiving unit (13, 31, 40) and at least one thermal energy releasing unit (5, 6, 8, 11, 36). The closed loop heating system also comprises a heat pump (23), transferring thermal energy from at least one first part (22, 26) of said fluid circuit (14, 15) to at least one second part (24, 29) of said fluid circuit (14, 15). |
