Autonomous boiler TESY EV 7/5 S2 200 60

TESY EV 200L 7/5 S2 2SP is a floor-standing vertical buffer tank with a capacity of 200 liters, equipped with two high-efficiency heat exchangers, enhanced thermal insulation, and reinforced anti-corrosion protection. The model is designed for complex heating and DHW systems that combine multiple heat sources — gas boiler, electric boiler, solid-fuel boiler, solar collectors, or a heat pump.

CrystalTech PRO enamel-coated tank

The tank is made of high-quality steel and protected with multi-layer CrystalTech PRO glass-ceramic enamel, resistant to:

▪️ corrosion,
▪️ high temperatures,
▪️ repeated heating and cooling cycles,
▪️ mechanical pressure loads.

This technology extends the tank’s service life several times compared to standard enamel coatings.

Two heat exchangers — expanded capabilities

The model is equipped with two coils (S2), providing:

▪️ simultaneous operation with multiple heat sources,
▪️ accelerated heating of the buffer volume,
▪️ high efficiency in solar-collector systems,
▪️ flexibility in building complex heating schemes.

Each coil has a large heat exchange surface, significantly improving overall system performance.

High-efficiency CFC FREE insulation

▪️ 50 mm polyurethane foam minimizes heat losses.
▪️ Energy efficiency class ERP B compliant with European 2024 standards.

Easy installation and maintenance

▪️ Floor-standing vertical installation — ideal for boiler rooms.
▪️ Large service flange for cleaning and internal inspection.
▪️ Option to install an electric heater (TEN) of the required power.
▪️ Sensor pockets for temperature probes and thermostats — ready for smart control systems.
▪️ Recirculation inlet — ensures continuous availability of hot water.

Maximum anti-corrosion protection

Two MG+ magnesium anodes ensure long-lasting cathodic protection:

▪️ the anode is easily accessible and replaceable,
▪️ extended tank lifespan and resistance to hard water.

Safety and reliability

▪️ high-quality electrical components (European standards),
▪️ external temperature indicator,
▪️ stainless steel heating element (when installed),
▪️ durable PVC casing resistant to moisture and mechanical damage.

Ideal for:

▪️ private homes of 120–250 m²,
▪️ hybrid systems with solar collectors / heat pumps,
▪️ multi-source and dual-circuit heating systems,
▪️ properties with high hot-water demand.
