Heating EOV-18, 18 kW 400 V, stainless steel, with pressure switch

Electric flow heaters are designed for heating water in pools and hot tubs, the operation consists of heating the flowing water with the heating element, the temperature of the heated water is set by a regulating thermostat. The heating element is switched by a contactor, which is controlled by the aforementioned thermostat and a flow safety indicator. For this reason, the heating requires so-called large automation - 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 by their construction for heating pool water, or water in other water circuits with a flow and temperature up to 40°C. Each heater must be installed in an electrical system behind a current protector. We therefore recommend complementing the device with a suitable type of automatic control from VÁGNER, which reliably ensures not only the desired comfort but also safety in operation. The difference between EOV and EOVp lies in the use of plastic for the actual casing and the use of a flow check valve instead of a pressure switch as a protective element for water flow.

Each electric heater EOV:

• utilizes the conversion of electrical energy into thermal energy
• is made of high-quality stainless steel with a high TITANIUM content AISI 316 (type EOV)
• is made of high-quality PVC (type EOVp)
• has a heating cartridge made of INCOLOY 800 stainless material with a high TITANIUM content, 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 glued 50 mm
• is equipped with a thermostat up to 40°C and thermal overload protection
• is equipped with a pressure switch, which checks the flow of water (type EOV)
• is equipped with 2 brackets for easy mounting
• higher outputs up to 36 kW upon agreement and order

Operating conditions:

• Minimum water flow: 4 m³/h (when presetting the pressure switch from 1,000 l/h)
• Operating pressure: 0-3 bar
• Connection: to water circuit with a pipe diameter of 50 mm
• Water quality: chloride content max. 150 mg/l
• chlorine content max 1 mg/l
• pH range 7.0-7.8
