Definitions

  • the present invention relates to a gas-powered water heater.
  • Water heaters are currently known which employ the heat produced by the combustion of a gas to produce hot water.
  • Such water heaters substantially consist of a water tank which is outwardly thermally insulated and downwardly provided with a combustion chamber, wherein the gas burner is inserted.
  • the combustion chamber is connected to the stack by means of one or more smoke-pipes extending in the tank of the water to be heated.
  • Gas-powered heaters comprising a combustion chamber which is isolated from the room in which the heater is installed and connected with the outside through a discharge duct for the burnt gases and an inlet duct for the combustion air.
  • a heater of this type is disclosed in the DE-A-2 201 317 wherein a discharge duct is provided having an exhaust portion extending through the water tank according to a vertical axis.
  • the heater according to the DE-A-2 201 317 has a limited efficiency owing to the fact that the inflow of combustion air depends on the natural draft created by the rising burnt gases.
  • the aim of the present invention is therefore to solve the above described problem by devising a gas-powered water heater which, besides having a particularly high thermal efficiency, is highly secure, eliminating or at least reducing the risk of gas leaks and easy to install.
  • the water heater according to the invention comprises a cylindrical water tank 1 which extends substantially vertically.
  • a combustion chamber 2 On the bottom of the tank 1 a combustion chamber 2 is arranged, inside which a gas burner 3, supplied by a conduit 4, is arranged.
  • the air required for combustion is sent to the chamber 2 by means of a pipe 5 vertically extending within the tank 1, adjacent to a pipe 6 for discharging the burnt gases.
  • a pipe 5 vertically extending within the tank 1, adjacent to a pipe 6 for discharging the burnt gases.
  • the tank 1 is outwardly surrounded by a jacket 9 of thermally insulating material, such as a cellular polyurethane and the like.
  • a dome 11 which is connected to the pipe 5.
  • An aspirator element 12 is arranged inside the dome 11 and is connected to the pipe 6 for forced ejection of the burnt gases through an exhaust pipe 13.
  • the pipe 13 is arranged coaxially inside a further pipe 14 through which the combustion air reaches the dome 11.
  • the combustion air before reaching the burner, is preheated by flowing in countercurrent along the burnt gas exhaust pipe 13 and subsequently releases part of this heat to the water contained in the tank by flowing in the pipe 5.
  • the forced draught provided by the aspirator 12 allows reduction of the fume passages and elimination of the flue, with obvious advantages as to efficiency and ease of installation.
  • the present invention offers a further advantage which can be particularly appreciated during the installation of the apparatus.
  • the advantage resides in the fact that it is possible to freely orientate the double pipe 13,14 which connects the apparatus with the outside environment, regardless of the position assumed by the water heater during mounting onto the wall.
  • the dome 11 is adapted to rest on a sealing gasket 15 and to be retained, by screw means, on the jacket top 10.
  • the rotation of the dome 11 occurs by pivoting on the central pipe 6 and also by virtue of a suitable gasket 16 provided between this pipe and aspirator 12 which moves with the dome.
