TESY BiLight Electric Hot Water Cylinder - 80 Litre

Yes, as an unvented cylinder, it must be installed with an appropriate safety group, including a pressure relief valve, to manage internal pressure.

This specific model is designed for vertical wall mounting. Please consult the manual if you require a horizontal configuration, as it may not be compatible.

The BiLight system uses two colors: one to show that the water is actively heating and another to indicate that the water has reached the set temperature.

The coating provides a smooth, hygienic surface inside the tank that is highly resistant to corrosion and the accumulation of limescale.

Yes, the glass-ceramic interior is specifically designed to resist corrosion, though periodic maintenance is recommended in very hard water regions.

Yes, the unit comes with a manufacturer's warranty. Please refer to your specific purchase documentation or the registration card provided in the box.

Check the electrical supply and ensure the circuit breaker is active. Verify that the thermostat is not set to the lowest position.

Verify power connectivity. If the power supply is confirmed, the internal thermal cut-out may have tripped; contact a professional technician.

Inspect the inlet pressure reducing valve and ensure the cold water mains tap is fully open.
