The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:

1, the utility model adopts and set up the time condensation heat exchanger on general gas heating hot water furnace foundation, this condensing heat exchanger adopts the high-quality corrugated stainless steel tubing to hover above in the stainless steel cavity, the high-temperature flue gas that burning produces is at first through the over-heat-exchanger heat exchange, flue-gas temperature is reduced to about 150 ℃ after over-heat-exchanger, under the effect of blower fan, be forced to then to blast in the condensation chamber of time condensation heat exchanger and carry out secondary heat exchange, the abundant contact heat-exchanging of flue gas and corrugated stainless steel tubing in condensation chamber, can be reduced to below 80 ℃ through flue-gas temperature after the heat exchange, produce a large amount of condensed waters simultaneously, made full use of the latent heat of vaporization of steam in the flue gas, also reduced the heat loss that smoke evacuation is taken away, its thermal efficiency is improved greatly, reach energy saving purposes.

2, the utility model is compared general gas heating hot water stove and has only been added a B-grade condensation heat exchanger and a cover condensed water collecting device, it is simple to compare fully pre-mixing gas combustion heating hot water furnace structure, B-grade condensation heat exchanger and condensed water collecting device can be made by oneself, cheap a lot of wouldn't can homemade full premix condensing heat exchanger with respect to domestic, thus the complete machine cost to compare fully pre-mixing gas combustion heating hot water stove much lower.

3, the utility model adopts independently time condensation heat exchanger system, the time condensation heat exchanger adopts the corrosion-resistant stainless steel bellows of high-quality and stainless sheet steel to make, place the port of export of blower fan, the time condensation heat exchanger is separated with burner, heat exchanger etc., thoroughly stopped the corrosion harmfulness of condensed water combustion system, heat exchanger and blower fan.

4, condensed water collecting device of the present utility model can form water seal artificially, the hidden danger that the flue gas when eliminating first the operation overflows, and it is unimpeded that condensed water is discharged.
