A fluid heating arrangement 10 comprises first and second fluid transport assemblies. The first fluid transport assembly 12 includes a first fluid heater 24 and a first conduit arrangement 26. The second fluid transport assembly 14 includes a second fluid heater 32 and a second conduit arrangement 34. A heat transfer apparatus 18 is connected to the first and second conduit arrangements to effect heat transfer between the first and second fluid transport assemblies. Preferably, the fluid heating arrangement comprises a third fluid transport assembly 16 including a third conduit arrangement 48 connected to a fluid storage means, such as a hot water tank 46. The first fluid heater may be a sealed system boiler and the second fluid heater may be a solar panel, heat pump or solid fuel open vented boiler unit. In use, the fluid heating arrangement particularly relates to hot water or central heating systems. In a further aspect, a heat transfer apparatus 18 comprises a plurality of fluid flow regions 62, 64 in heat transfer relation with each other, and first 66, 68, second 72, 70 and third 74, 76 inlets and outlets in fluid communication with respective fluid flow regions. |
