The heat exchanger 170 comprises a longitudinal hollow body 176 having an inlet 172 and an outlet 174. A plurality of pipes 182 extend transversely through the body across a fluid path defined between the inlet and outlet. Ideally the heat exchanger includes a baffle 178 in the form of a plate to divide the fluid path into an inlet side and an outlet side, the pipes being provided on the inlet side of the baffle. Preferably the pipes are longitudinally and vertically spaced so as to define an internal body region 184 adjacent the inlet that tapers towards an opposing end 179 of the body. The heat exchanger is ideally immersed in a body of water contained by a water heating tank (132, figure 2) of a recreational vehicle such as a caravan (12, figure 1) whereby the inlet receives hot combustion products from a burner head such that the outlet is a flue. In this configuration the pipes permit water to pass through the heat exchanger and be heated by the combustion products passing through the fluid path, thereby providing a water heater.
