Efficiency and comfort first

They include an internal coil for connection to a generator or a solar system for the production of domestic hot water.

The 300 and 500 l cylinders made of vitrified sheet steel are supplied in two separate parts, one with the cylinder and the other with the insulation and casing to ease the transport to the installation site.
