Product information

Description

The TESY BiLight 80 SE is an 81-liter combined water heater engineered for reliable domestic hot water production. This versatile appliance features a dual-heating system, allowing it to operate via an integrated 2000 W electric heating element or through an internal heat exchanger connected to a central heating system. Designed for vertical wall mounting, this steel-constructed unit offers a balance of efficiency and durability for residential environments.

Advantages

The primary advantage of the TESY BiLight 80 SE is its flexibility in energy sources, which allows users to switch between electric heating and central heating integration to optimize energy consumption. The robust steel construction ensures long-term reliability, while the vertical design saves valuable floor space. Its intuitive BiLight indication system provides clear visual feedback on the operating mode, ensuring simple and efficient management of your hot water supply.

Suitable for

  • Residential homes requiring a consistent hot water supply
  • Households with existing central heating systems
  • Properties where space-saving vertical installation is required

When it may not be suitable

This unit is not suitable for horizontal installation or floor-standing applications. It may also be insufficient for large commercial facilities or households with extremely high peak hot water demands that exceed the capacity of an 81-liter tank.

Key specifications

  • Capacity: 81 liters
  • Power: 2000 W
  • Mounting: Vertical
  • Material: Steel
  • Maximum working pressure: 8 Bar
  • Dimensions: 89 cm (height) x 48 cm (width) x 49 cm (length)
  • Color: White

How to use

The water heater should be installed vertically on a wall capable of supporting its weight when full. Connection to the water mains and the central heating system must be performed by a qualified technician to ensure safety and compliance with local regulations. Once installed, the unit can be operated via the control panel to select the desired heating mode. Regular maintenance, including checking the safety valve and the condition of the heating element, is recommended to ensure optimal performance.

What to consider before purchase

  • Ensure the installation wall is structurally sound for a vertical mount
  • Verify that your central heating system is compatible with the internal heat exchanger
  • Confirm that the 81-liter capacity meets your household's daily hot water requirements
  • Check the available space against the unit dimensions of 89x48x49 cm
Usage recommendations: For maximum energy efficiency, utilize the central heating heat exchanger during the heating season and switch to the electric heating element during warmer months. Always ensure the tank is completely filled with water before activating the electric heating element to prevent damage.
