The invention discloses a kind of vehicle-mounted gas formula water heaters, its water pipeline includes inlet segment, the first bringing-up section, the second bringing-up section and water exit end, wherein, inlet segment is shortened, and the first bringing-up section is directly heated rapidly by burning heater, and the second bringing-up section is heated with coiling heat exchanger mode, so that, inlet segment reduces to form condensed water because surface area reduces, and the condensed water that the first heating section surface is formed evaporates rapidly, and the surface of the second bringing-up section and water exit end is difficult to form condensed water.Water pipeline of the invention effectively reduces the generation of condensed water, can or avoid the accumulation of condensed water at least to a certain extent, and can reduce the formation of scale in water pipeline, conducive to the service life for extending water heater, securely and reliably. |
