800-Liter Buffer Tank with Two Coils (2.2 m²)

800-liter buffer tank insulated with polyurethane foam.

Warranty: 48 months

• Engineered end caps ensure resistance to high pressure;
• Manufactured from 3 mm thick steel;
• Each tank is pressure-tested at 5 bar;
• High-quality welded seams.

The buffer tank is designed for collecting, storing, and transferring excess hot water from various heat sources. It stores hot water heated by the boiler and makes it available when it is actually needed. This solution offers very high efficiency and energy savings.

In a solid fuel boiler system. The boiler operates at full capacity, while excess heat is transferred to the buffer tank. A circulation pump then supplies hot water from the tank to the central heating system.

In an electric boiler system. The electric boiler heats water only during Tariff II (the cheaper night-rate tariff), while the buffer tank stores thermal energy during this lower-cost period.

Electric heating elements powered by photovoltaic (solar) panels can also be connected.

Advantages of Installing a Heat Storage Tank:

• instantly stores heat and releases it when needed;
• saves 30–50% on solid fuel consumption and reduces the frequency of boiler refueling;
• protects the boiler from overheating through continuous circulation;
• provides hot water heating for domestic use;
• compatible with heat pump systems.
