• Copper heat exchanger for connection with the central heating boiler.
• Copper heat exchanger for connection with a series of solar collectors.

The thermal performance is superior because copper has 7 times the heat transfer coefficient compared to steel.

Insulation made of ecological expanded polyurethane with a high content of 44 Kg/m3, 65mm thick, and thermal conductivity coefficient λ=0.0180 W/mK.

Outer casing made of Aluzinc sheet pre-painted in white-gray color RAL 9002.
