Storage tank TESY 80L EV80 46 for heat pump

TESY EV80 46 (80 liters) is an enlarged buffer tank designed for medium-capacity heating, cooling, and heat pump systems. Thanks to its increased volume, the tank effectively stores thermal energy and compensates for temperature fluctuations, ensuring stable operation of the equipment in any climate.

Key structural features

Reinforced thermal insulation — 50 mm (high-density polyurethane)

Extremely low heat losses, high energy efficiency and stable performance throughout the day.

8 connection ports G 1¼"

Allow implementation of complex hydraulic layouts, including simultaneous connection of a hydraulic separator, boiler, buffer tank and heat pump.

Energy efficiency class B

Complies with modern European energy-saving standards.

Stratification brackets

Create temperature layers inside the tank, increasing heat exchange efficiency and improving system response to load changes.

Anti-condensation construction

Optimized for cooling systems; an optional kit prevents condensation droplets on the tank surface.

Drain G 1½" and air vent G ¾"

Provide easy maintenance and prevent air-lock formation.

Compatible with electric heater (TEN)

Allows the tank to be used in hybrid systems: solid fuel boiler + electric heater + heat pump.

Durable enamel-coated steel tank

Ensures long-lasting protection against corrosion and aggressive environments.
