APPARATUS FOR RECOVERING HEAT FROM HEATED WASTE WATER
Apparatus (2) for recovering heat from heated waste water (4), which apparatus (2) comprises: (i) a first pipe (6) for receiving unused pressurised mains water (8); (ii) propeller means (10) positioned in the first pipe (6) such that propeller means (10) is caused to rotate by flow of the unused mains water (8) in the first pipe (6); (iii) a plurality of first magnets (12) provided on the propeller means (10); and (iv) a sealed system (14) for containing a heat transfer fluid (16); and the sealed system (14) being such that: (v) the sealed system (14) comprises a first part (18) which covers a length (20) of the first pipe (6), the propeller means (10) and the first magnets (12); (vi) the sealed system (14) comprises coupling means (22) which is caused to operate by the first magnets (12), and in which in operation pumps the heat transfer fluid (16) around the sealed system (14); (vii) the sealed system (14) comprises a second part (24) which covers a length (26) of a second pipe (28) for receiving the heated waste water (4); (viii) the length of the second pipe (28) which is covered by the second part (24) of the sealed system (14) is sufficiently long for heat to be transferred from the heated waste water (4) to the heat transfer fluid (16); and (ix) the length of the first pipe (6) which is covered by the first part (18) of the sealed system (14) is sufficiently long for heat to be transferred from the heat transfer fluid (16) to the unused mains water (8), whereby the apparatus (2) is such that heat from the heated waste water (4) is used to heat the unused mains water (8) and thereby reduce the cost of heating the unused mains water (8).
