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.
  • 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 high secure, eliminating or at least reducing the risk of gas leaks.
  • an object of the invention is to provide a gas-powered water heater which can be conveniently employed to heat rooms and allows simultaneous production of hot water.
  • a further object of the invention is to provide a gas-­powered water heater which is simple in concept, easy to install and to use and safely reliable in operation.
  • 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 10 of thermally insulating material, such as cellular polyurethane and the like.
  • the outer insulation jacket 10 extends at a distance from the cylindrical body of the tank 1 and defines therewith an interspace 11 which is downwardly open onto the room. Upwardly, instead, the jacket 10 defines a chamber 12 which annularly surrounds a dome 13 arranged at the top of the tank 1 and is connected, through an annular opening 14, to the interspace 11.
  • the chamber 12 laterally accomodates a fan element 15 having a horizontal axis and facing an opening 16 formed in the outer wall of the chamber 12.
  • the fan 15 appropriately operated, is adapted to achieve a forced circulation of air through the interspace 11.
  • the water heater is capable of providing air for heating purposes, simultaneously with hot water.
  • the air sucked by the fan flows along the warm wall of the tank 1, moving from the bottom upwards, and then flows out of the opening 16 at a correspondingly high temperature.
  • the fan 15 may be stopped when such heating is not required.
  • An aspirator element 17 is arranged inside the dome 13 and is connected to the pipe 6 for forced ejection of the burnt gases through an exhaust pipe 18.
  • the pipe 18 is arranged coaxially inside a further pipe 19 through which the combustion air reaches the dome 13, which in turn is connected to the tube 5.
  • the combustion air before reaching the burner, is preheated by flowing in countercurrent along the burnt gas exhaust pipe 18, 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 17 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 18-19 which connects the apparatus with the outside environment, regardless of the position assumed by the water heater during mounting onto the wall.
  • the dome 13 is adapted to rest on a sealing gasket 20 and to be retained, by screw means, on the jacket 9.
  • the rotation of the dome occurs by pivoting on the central pipe 6 and also by virtue of a suitable gasket provided between this pipe and the aspirator 17 which moves with the dome.
  • the materials employed, the shape and the dimensions may be any according to the requirements.
