- Low consumption of only 300W — keep water warm without high energy bills
- Simple installation in 15-20 minutes — the flange with silicone gasket easily fastens with the included nut, no special tools required
- Long lifespan — stainless steel resists corrosion and deposits, working for years in a humid environment
- Universal compatibility — integrates into most unpressurized boilers and solar panels with a standard opening
- Operational safety — efficient heat transfer and secure sealing prevent leaks and overheating
- Suitable for solar systems — can be used as an auxiliary heating source on sunless days
How it works and how to install it
The heater is installed through the dedicated opening of the boiler or tank, secured with the included nut and silicone gasket for sealing. After connecting to 220V AC via the threaded terminals, the stainless steel heating element is fully immersed in the water and begins heat transfer. It is recommended to use a thermostat for automatic temperature control and maximum energy saving.
Important: never turn on the heater without water in the tank and ensure the element is completely submerged to avoid damage.
Frequently Asked Questions
Can it be used in a pressurized boiler?
No, this model is designed exclusively for unpressurized systems — open-tank boilers or solar panels with atmospheric pressure circuits.
Do I need a thermostat or does it work by itself?
The heater does not have an integrated thermostat. It is recommended to install an external thermostat for automatic temperature control and increased safety.
How long does it take to heat the water?
The time depends on the water volume and initial temperature. At 300W, it is ideal for maintaining temperature or gradual heating in tanks up to 100 liters.
