摘要： Condensate collection and discharge unit comprising a fluid collection reservoir having a fluid inlet, and a fluid outlet opening and comprising a valve associated with the fluid outlet opening for preventing flue gases to be discharged from the outlet opening. The fluid collection reservoir is movable between at least one first position in which the fluid outlet opening is closed by the valve, and at least one second position in which the fluid outlet opening is disengaged from the valve so as to allow for the discharge of accumulated fluid from the fluid collection reservoir. A biasing member biases the fluid collection reservoir in the at least one first position. The biasing force may be overcome by a gravitational force generated by a predefined amount of fluid collected in the fluid collection reservoir, so as to move the fluid collection reservoir under gravity into the at least one second position.

摘要： A fin (13) includes a cut and raised slit (13b) and a cut and raised wall portion (13a). The cut and raised slit (13b) is formed in a region (RA) adjacent to at least one through hole (13ca) of a plurality of through holes (13ca) in a first direction (DA) and has a tunnel-shaped hole (13ba1, 13bb1, 13bc1) extending in a second direction (DB) intersecting the first direction (DA). The cut and raised wall portion (13a) is located in the second direction (DB) of the cut and raised slit (13b), protrudes toward a main surface (MS) of the fin (13), and extends along the first direction (DA). Thus, a heat exchanger and a water heater capable of sufficiently conducting an amount of heat of a combustion gas to a heat conduction pipe even in a blind spot of a flow of the combustion gas of the heat conduction pipe and suppressing noise can be realized.

摘要： Many dwellings use condensing boilers as their source of heating and domestic hot water because such boilers offer increased efficiency when compared to non-condensing boilers. The operation of a condensing boiler is well known and need not be described in detail here. However, by way of a reminder, a condensing boiler seeks to cool the gas produced from its burner portion to below the dew point such that water vapour in the heated gas starts to condense thereby giving up its latent heat of vaporisation. In practise this means seeking to cool the flue gas to below 58°C or thereabouts. The condensate, which still has a temperature of around 57°C or 58°C is then ducted along a drain path and expelled. The present invention relates to a condensate heat exchanger for use with a condensing boiler, characterised by a heat exchanger being placed in a condensate drain path for draining condensate from the boiler.
