TESY 500L storage tank 2SP

TESY 500L (2SP) V15/7S2 P6 is an advanced 500-liter buffer tank equipped with two high-performance heat exchangers.

Thanks to the dual-coil configuration, the tank can be connected simultaneously to two independent heat sources:

✔ heating boiler + solar collector
✔ solid-fuel boiler + heat pump
✔ electric boiler + gas boiler

and many other hybrid heating combinations.

This makes the model ideal for modern energy-efficient homes and hybrid heating systems.

Two powerful heat exchangers

They provide:

▪️ faster heating,
▪️ improved heat transfer,
▪️ the ability to combine renewable and traditional heat sources.

Enamel-coated steel tank

The CrystalTech PRO enamel withstands high temperatures, water acidity and long-term exposure to heat-transfer fluids.

Thick insulation — 50 mm

Rigid polyurethane (CFC Free) ensures excellent heat retention even with large water volumes — crucial for cyclic operation of:

▪️ solid-fuel boilers,
▪️ heat pumps,
▪️ solar thermal systems.

Precise temperature control

Like the single-coil version, TESY 500L (2SP) includes:

▪️ external temperature indicator,
▪️ four sensor pockets,
▪️ option to install an electric heater (TEN), increasing flexibility and overall functionality.

Reliability and safety

▪️ enlarged magnesium anode
▪️ built-in safety valve
▪️ corrosion resistance
▪️ ERP-class energy efficiency

Easy installation and maintenance

A large service flange and durable plastic outer casing allow:

▪️ quick cleaning,
▪️ easy servicing,
▪️ simple upgrades.
