Non-pressurised electric water heaters
These heaters are suitable for facilities where an instant need for a small quantity of hot water may arise, such as in kitchens, guest rooms, washrooms and workshops. The water is heated at the point where it is needed, therefore conduit pipes are short, so thermal losses are low. The heaters are manufactured with dimensions that make them suitable for over and underbasin installation. The tank is manufactured from hygienically impeccable plastic material (polypropylene).
- Volumes: 5 and 10 l.
- Supply of one outlet only.
- Underbasin and overbasin mounting option. Depending on water heater design, suitable non-pressurized underbasin or overbasin mixer tap shall be used.
- Control knob for optional setting of water temperature in the heater, up to 75 °C.
- Indicator of electric heating element operation.
- Tank made of hygienically safe polypropylene.
Electric immersion heating element
The immersion heater is in direct contact with water. It is made of copper, providing high corrosion resistance and long life. The Mg anode additionally protects the enamelled tank against corrosion. Properties
