Product code

Electric flow-through heaters are designed for heating water in pools and hot tubs. Their operation consists of heating the flowing water with the heating element, and the temperature of the heated water is set by the regulating thermostat. The heating element is controlled by a contactor, which is operated by the aforementioned thermostat and a flow indicator safety device. For this reason, it is necessary to have a "big automation" - a 24-hour filtration programmer, current protector (protection against dangerous voltage), thermal overload protection of the motor, contactor, and heating switch.

The swimming pool electric flow-through water heaters types EOV, EOVp, EOVk, EOVTi, EOVnTi, and EOVn are specifically designed for heating swimming pool water or water in other water circuits with a flow rate and temperature of up to 40°C. Each heater must be installed in an electrical system after a current protector. It is therefore recommended to complement the device with a suitable type of automatic control from VAGNER, which reliably ensures not only the desired comfort but also operational safety. The difference between EOV and EOVp lies in the use of plastic for their own heat exchanger and the use of a flow valve instead of a pressure switch as a protective device for water flow.


Each electric EOV heater:

  • converts electrical energy into heat energy
  • is made of high-quality stainless steel with a high TITANIUM content AISI 316 (EOV type)
  • is made of high-quality PVC (EOVp type)
  • has a heating element made of INCOLOY 800 stainless material with a high TITANIUM content, ensuring the best quality
  • is 100% leak tested
  • can be connected to the water circuit via 1.5" thread, 50 mm hose, or 50 mm glue
  • is equipped with a thermostat up to 40°C and a thermal fuse
  • is equipped with a pressure switch that monitors water flow (EOV type)
  • is equipped with 2 brackets for easy installation
  • higher powers up to 36 kW available by agreement upon order

Operating conditions:

  • Minimum water flow: 4 m³/h (when the pressure switch is pre-set at 1,000 l/h)
  • Operating pressure: 0-3 bar
  • Connection: to the water circuit with a pipe diameter of 50 mm
  • Water quality: chloride content max. 150 mg/l
  • chlorine content max. 1 mg/l
