A water heater made of plastic material comprises an external case (7) and a main body (2) including, preferably but not exclusively, two semi-shells (2a, 2b) soldered to create a body which can withstand temperature and pressure. The two semi-shells (2a, 2b) and the external case (7) are made of compatible and recyclable thermoplastic materials, in particular mixtures of polymers reinforced with glass fibers, preferably in a percentage equal to or higher than 30%. <IMAGE> |
