TECHNICAL DESCRIPTION

The calorifier is designed to heat water via a lower coiled heat exchanger from various sources, while providing accumulation and storage for DHW. The tank features a flanged inspection port with a sealed cover for periodic maintenance access. A fitting above the heat exchanger is provided to install an electric heating element. Two magnesium anodes ensure corrosion protection.

MATERIALS

Tank and heat exchanger are constructed from cold-rolled carbon steel with an internal double-layer enamel coating, baked at 860°C by DIN 4753 standards.

THERMAL INSULATION

Rigid polyurethane foam insulation, 50 mm thick, encased in a zippered “sky” finish casing, compliant with all requirements of the ErP 2009/125/EC Directive.
