Product Description

Tesy's BiLight range of water heaters ensure constant domestic hot water production using small amount of electrical energy. This is achieved by using high quality materials and innovative technologies. The heat exchangers allow the water heater to be connected to the central heating system as well as a solar system, thus producing hot water without using electrical energy

Product characteristics

  • Heat exchanger - an economical and effective method of heating domestic water, designed to be connected to a central heating system (closed type) and a solar system simultaneously
  • Thermal sensor sleeve - The model has a thermal sensor sleeve next to the lower end of the heat exchanging coil for even more precise control of the water heater.
  • Built-in TURBOLATOR - the turbolator is an element placed throughout the length of the heat exchanging coil designed to break apart the linear flow of the heating fluid inside the coil. This causes the molecules of the fluids to impact the turbolator, which creates thermal energy and increases the efficiency.
  • PISTON effect - Tesy BiLight water heaters are equipped with a new type of cold water nozzle. It's unique design reduces the quick mixing of the water inside the tank. Incoming cold water remains on the bottom of the tank and gently pushes the hot water to the top, creating the PISTON effect. This creates up to 15% more hot water.
  • BiLight switch - The BiLight power switch has two operation modes, indicated by changing the colour of the light indicator.
  • Higher energy efficiency, achieved by removing the thermal link between the tank and the mounting console.
  • Enameled coating of the water tank.
  • Magnesium anode protector - it has up to 50% increased lifespan and can be easily replaced.
  • Easy to use thermostat with precision control of the water temperature as well as heat and electrical surge protection.
  • High efficiency insulation made of extruded polyurethane.
  • Reliable heating element in accordance with the European quality regulations.
  • Flange - the heating element and the anode protector are mounted on a flange which makes their replacing fast and easy.
  • Freeze protection operation mode.
