Autonomous boiler TESY EV 15S 500 75

TESY EV 500L 15S 75 1SP is a large-capacity 500-liter buffer tank with a single heat exchanger, designed for high-power heating systems, large cottages and commercial facilities. This is professional-grade equipment engineered for stable operation under heavy loads and high hot-water consumption.

Steel tank with enhanced anti-corrosion protection

Thanks to the CrystalTech PRO enamel coating, the tank provides:

▪️ perfectly smooth internal surfaces,
▪️ resistance to rust and erosion,
▪️ durability even under constant thermal fluctuations,
▪️ safety for contact with potable water.

Next-generation thermal insulation (50 mm PU)

The unit features dense, high-quality polyurethane foam:

▪️ CFC-free,
▪️ eliminates heat loss,
▪️ ensures ERP C energy-efficiency class for a 500-liter volume.

High-performance single heat exchanger

The large coil is designed for powerful boilers:

▪️ speeds up heating of large water volumes,
▪️ ensures uniform circulation,
▪️ suitable for radiator circuits and high-pressure hydraulic systems.

Extended magnesium protection

The model uses two MG+ magnesium anodes that:

▪️ protect the tank’s internal surface,
▪️ prevent corrosion at high operating temperatures,
▪️ significantly extend the system’s lifespan.

Thought-out construction

▪️ large service flange for cleaning and inspection,
▪️ external temperature indicator,
▪️ high-strength PVC casing,
▪️ pockets for sensors and thermostat,
▪️ recirculation inlet,
▪️ silent operation.

Where TESY EV 500L is used

▪️ cottages and large houses of 250–500 m²,
▪️ mini-hotels, hostels, restaurants, laundries, workshops,
▪️ high-capacity heating and DHW systems,
▪️ facilities with continuous, intensive hot-water consumption.
