Abstract
A water heater made of plastic material comprises an external case (7) and a main body (2) including two semi-shells (2a,2b) soldered to create a body which can withstand temperature and pressure. The two semi-shells (2a, 2b), each of which is fitted with radial reinforcing elements (8) 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%.
Claims8
A water heater made of plastic material, comprising a main body (2) including two semi-shells (2a, 2b), an opening (5) being made on the main body for inserting a heating element (3), wherein each semi-shell (2a, 2b) includes a peripheral border (9) with coupling means (10a, 10b) which can be reciprocally coupled to form a band with higher resistance, radial reinforcing elements (8) extending from each peripheral border (9) to converge into a central area of each semi-shell (2a, 2b).
