TESY 500L storage tank 1SP

TESY 500L (1SP) V15S P5 is a high-efficiency 500-liter buffer tank designed for storing and distributing heat in heating systems of private homes, cottages and commercial buildings. The model is equipped with an enlarged heat exchanger (1SP), ensuring fast and stable heating of the water from any boiler — solid-fuel, gas, electric or pellet.

Reinforced enamel-coated steel tank

The inner reservoir is made of steel and coated with CrystalTech glass-ceramic enamel, providing:

▪️ corrosion resistance,
▪️ protection against scale,
▪️ high-temperature durability.

INSUTECH insulation — 50 mm

The dense rigid polyurethane insulation (50 mm, CFC-free):

▪️ significantly reduces heat losses,
▪️ increases the overall energy efficiency of the heating system.

High-precision temperature control

▪️ external thermometer,
▪️ 4 sensor pockets — allowing integration with any control system or weather-dependent automation.

Connection and recirculation

The tank includes a dedicated recirculation port, ensuring:

▪️ continuous circulation of the heat carrier,
▪️ fast distribution of heat throughout all heating circuits.

Protection and durability

▪️ enlarged magnesium anode provides reliable electrochemical corrosion protection;
▪️ built-in safety valve ensures safe pressure operation.

Easy maintenance

A large removable flange provides full access to:

▪️ inspection,
▪️ cleaning,
▪️ installation of an electric heater,
▪️ preventive maintenance.

Option to install an electric heater (TEN)

Allows using the tank as a combined water heater — ideal for summer operation without running the main boiler.
