Opro + H is a medium capacity volumetric water heater with a copper heater. The temperature can be set with an external knob, the heater's operating range starts from 7 ° C and ends at 65 ° C. dielectric muff. The interior is protected against corrosion by ceramic enamel enriched with titanium and copper oxide, the O'pro system, which equalizes electromagnetic potentials, and an anode made of magnesium. A copper heater and thermal insulation made of polyurethane foam are responsible for maintaining the set temperature in the heater, additionally, the appropriate shape of the deflector prevents mixing of cold and already heated water. The thermometer that is equipped with the device shows the current water temperature.
