TECHNICAL DESCRIPTION
The calorifier’s enlarged heat exchanger surface area makes it ideally suited for integration with heat pumps. Additionally, the increased heat exchanger area enables connection to high-capacity heat sources, delivering exceptional DHW output despite the relatively compact tank volume. 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.
