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.
