Electric flow heaters are designed for heating water in pools and hot tubs, the operation consists of heating the flowing water using the heating element, the temperature of the heated water is set by the regulating thermostat. The heating element is controlled by a contactor, which is controlled by the aforementioned thermostat and a flow indicator. For this reason, a so-called large automation is required for heating - a 24-hour filtration programmer, a current protector (protection against dangerous touch voltage), motor thermal protection, contactor, and heating switch.

Pool electric flow water heaters type EOV, EOVp, EOVk, EOVTi, EOVnTi, and EOVn are specially designed for heating pool water or water in other water circuits with a flow and temperature of up to 40°C. Each heater must be installed in an electrical system behind a current protector. Therefore, we recommend supplementing the device with a suitable type of automatic control from VÁGNER, which reliably ensures not only the desired comfort but also operator safety. The difference between EOV and EOVp lies in the use of plastic on the actual heating body and the use of a flow valve instead of a pressure switch as a protective element for water flow.


Each EOV electric heater:

  • utilizes the conversion of electrical energy into thermal energy
  • is made of high-quality stainless steel with a high TITANIUM INCOLOY 316 (EOV type)
  • is made of high-quality PVC (EOVp type)
  • has a heating cartridge made of stainless steel material INCOLOY 800 with a high TITANIUM, which guarantees the best quality
  • is 100% tested for tightness
  • can be connected to the water circuit via a 1.5" thread, a 50 mm hose or 50 mm adhesive
  • is equipped with a thermostat up to 40°C and a thermal fuse
  • is equipped with a pressure switch that controls water flow (EOV type)
  • is equipped with 2 brackets for easy mounting
