Abstract: A heat exchanging unit exchanges heat between a fluid to be heated and exhaust gas. The heat exchanging unit includes a heat exchange portion, a header portion, and a flow changing portion. The heat exchange portion includes a heat exchange pipe in the interior of which the fluid to be heated flows. The header portion is connected to the heat exchange pipe, the header portion allowing the fluid to be heated to flow from the header portion to the heat exchange pipe or from the heat exchange pipe to the header portion. The flow changing portion changes the state of flow of the exhaust gas introduced into the heat exchange portion.

Abstract: A heat exchanger tube for transferring a heat of an exhaust gas to a fluid to be heated includes a turn-back portion formed in an intermediate portion of the heat exchanger tube and a reciprocating conduit portion. The reciprocating conduit portion includes a conduit portion leading from a starting end of the heat exchanger tube to the turn-back portion, and a conduit portion leading from the turn-back portion to a terminal end of the heat exchanger tube. A space equal to or greater than the outer diameter of the conduit portions is provided between these conduit portions.

Abstract: A piping connection unit of a combustion apparatus supplying and discharging air through a duct includes an apparatus-side connecting part, a connecting part and a spacer. The apparatus-side connecting part is to be connected to an air supply part or an exhaust part of the combustion apparatus. The connecting part has a diameter larger than a diameter of the apparatus-side connecting part, and communicates with the apparatus-side connecting part to be connected to a duct to be inserted from an opening part. The spacer is detachably disposed in the connecting part. The spacer is disposed between an inner wall of the connecting part and the duct to be inserted when the duct has a pipe diameter smaller than an inner diameter of the connecting part. The spacer is removed from the connecting part when the duct has a pipe diameter equivalent to the inner diameter of the connecting part.

Abstract: The filter device includes a supply air introducing part, a filter main body part and a discharge part. The supply air introducing part takes in an outside air. The filter main body part includes a ventilation pipe connected to the supply air introducing part to allow the outside air to flow through the ventilation pipe and a filter housing part being equipped with an outflow hole allowing the outside air to flow outside at a position higher than a position of the opening part of the ventilation pipe to separate, from the outside air, a liquid in a liquid state or a state close thereto. The liquid is taken in together with the outside air. The discharge part discharges at least the separated liquid from the filter main body part.
