A heat exchanger is located in the tank and comprises a hollow body having a mouth coupled to the heat exchanger inlet and a flue outlet coupled to the heat exchanger outlet. A burner device has a burner head that is located at least partly located in the mouth inside said hollow body. ## Claims ### Claim 1 A heating apparatus comprising: a tank, the tank having a tank inlet, a tank outlet, a heat exchanger inlet and heat exchanger outlet; a heat exchanger located in the tank, the heat exchanger comprising a hollow body having a mouth coupled to the heat exchanger inlet and a flue outlet coupled to the heat exchanger outlet; a burner device, the burner device having: an air intake; a burner head including an ignition device; a gas injection; and a burner body providing a fluid flow channel between said air intake and said burner head, wherein said gas injector is configured to inject combustible gas into said fluid flow channel such that said burner body supplies a mixture of combustible gas and air to the burner head in use, and wherein said burner body is located outside of said tank and said burner head, including said ignition device, is located in the mouth inside the hollow body; and a plurality of pipes extending transversely through the body across the fluid path between the mouth and the flue outlet, the pipes being open to the interior of the tank so that in use they are filled by the contents of the tank, and the pipes defining on one side an internal body region that narrows in a direction from the mouth towards the opposite end of the body, and an internal body region on the other side that widens in a direction from the mouth towards the opposite end of the body. ### Claim 2 (depends on 1) The heating apparatus of claim 1, wherein the heat exchanger inlet and heat exchanger outlet are disposed in a common face of the tank. ### Claim 3 (depends on 2) The heating apparatus of claim 2, wherein the heat exchanger inlet and the heat exchanger outlet are provided in the same face that includes the tank outlet and the tank inlet. ### Claim 4 (depends on 1) The heating apparatus of claim 1, wherein the hollow body is not in contact with the internal surfaces of the tank. ### Claim 5 (depends on 1) The heating apparatus of claim 1, wherein the body is configured to define at least one substantially U-shaped internal fluid path between the mouth and the flue outlet. ### Claim 6 (depends on 1) The heating apparatus of claim 1, further comprising a baffle in the body to partition the internal body space between the mouth and flue outlet to define a fluid path that runs from the mouth away from the mouth end of the body towards the opposite end of the body, around a free end of the baffle and back to the flue outlet. ### Claim 7 (depends on 6) The heating apparatus of claim 6, wherein the baffle comprises a plate that extends longitudinally of the body having one end located at the mouth end of the body separating the mouth and flue outlet, and the other end located adjacent but spaced from the other body end. ### Claim 8 (depends on 1) The heating apparatus of claim 1, wherein the pipes are spaced-apart in a longitudinal direction of the body, a first one of the pipes preferably being located adjacent the mouth and a last one of the pipes preferably being located adjacent the opposite end of the body. ### Claim 9 (depends on 1) The heating apparatus of claim 1, wherein the pipes are spaced-apart in a direction perpendicular with longitudinal and transverse axes of the body. ### Claim 10 (depends on 9) The heating apparatus of claim 9, wherein the pipes are arranged such that, from a first pipe to a last pipe, there is a vertical spacing from one pipe to the next is in the same vertical direction. ### Claim 11 (depends on 1) The heating apparatus of claim 1, including a baffle in the body to partition the internal body space between the mouth and the flue outlet to define a fluid path that runs from the mouth away from the mouth end of the body toward the opposite end of the body, around a free end of the baffle, and back to the flue outlet, and wherein the pipes are provided on a mouth side of the baffle. ### Claim 12 (depends on 11) The heating apparatus of claim 11, wherein the first pipe is located relatively close to the baffle in comparison with the or each other pipe, the or each other pipe being located progressively further from the baffle than the first pipe. ### Claim 13 (depends on 1) The heating apparatus of claim 1, wherein the heat exchanger body comprises first and second parts which are formed separately and joined together, the first and second parts being shaped to define together a desired body shape. ### Claim 14 (depends on 1) The heating apparatus of claim 1, wherein insulating material is provided around at least the sides of the tank, but not at the top of the tank. ### Claim 15 (depends on 1) The heating apparatus of claim 1, wherein the tank is located inside a housing. ### Claim 16 (depends on 15) The heating apparatus of claim 15, wherein the housing has a top portion that is contiguous with a top of the tank. ### Claim 17 (depends on 15) The heating apparatus of claim 15, wherein the housing has one or more mounting devices for mounting a top portion of the housing to a surface. ### Claim 18 (depends on 15) The heating apparatus of claim 15, wherein the housing is shaped and dimensioned to provide space between at least the sides of the tank for receiving insulating material. ### Claim 19 (depends on 15) The heating apparatus of claim 15, wherein the housing is shaped and dimensioned to define a head space at an end face of the tank, the head space being shaped and dimensioned to receive at least a body section of the burner device. ### Claim 20 A heat exchanger comprising a hollow body having a fluid inlet and a flue outlet wherein a plurality of pipes extend transversely through the body across a fluid path between the mouth and the flue outlet, the pipes being open to the external environment of the hollow body, the body being configured to define a substantially U-shaped fluid path between the mouth and the flue outlet, and wherein the pipes define on one side an internal body region that narrows in a direction from the mouth towards the opposite end of the body, and an internal body region on the other side that widens in a direction from the mouth towards the opposite end of the body. ### Claim 21 (depends on 1) The heating apparatus of claim 1, wherein said burner head includes an inlet, and a mixing chamber between said ignition device and said inlet, said burner body being coupled to said burner head to supply said mixture of air and combustible gas to said mixing chamber via said inlet, and wherein said mixing chamber is located in the mouth inside the hollow body.
