The open chamber and pilot flame boiler Euroterm SIMPLEX 20 P is a boiler in which the main burner is ignited with the help of a pilot light that remains always on. Traditional boilers only use a part of the sensible heat of the combustion gases because it is necessary to avoid the condensation of the gases, which would lead to corrosive phenomena.
Indeed, traditional boilers only use a part of the sensible heat of the combustion gases because it is essential to avoid the condensation of the gases, which would cause corrosive phenomena. The water vapor generated by the combustion process is then dispersed into the atmosphere through the chimney, along with the associated latent heat. In contrast, gas heating based on condensing technology reduces fuel consumption by up to 20% when replacing this boiler.
Annual Maintenance and Safety
To ensure that the boiler maintains its safety and efficiency performance, it is essential to subject it to regular maintenance every year. The annual review is vital to ensure the safety and proper ongoing operation of the device.
Boiler Checklist: Winter Preparation
- Boiler Pressure Check: Verify the pressure via the pressure gauge to ensure optimal performance.
- Thermostat Management: Check the batteries of the thermostat for accurate temperature regulation.
- System Pressure: Ensure that the heating system pressure is appropriate, between 1 and 1.5 bar.
- Professional Maintenance: Schedule professional maintenance for cleaning and inspection of your Euroterm SIMPLEX 20 P boiler.
Check the Heating System's Pressure
At least every quarter, ensure that the system's pressure is correct; it should be between 1bar and 2bar. Also check this in the summer, as the boiler uses radiator water (only in internal circulation) to heat domestic hot water. If the pressure is low, the boiler is equipped with a component that stops the production of heating or hot water.
Remember to use the filling tap, found under the appliance. Open it and check that the pressure gauge reaches 1.5bar, then close it.
Effective Temperature Settings
To make the most of your Euroterm SIMPLEX 20 P boiler, it's crucial to understand how to effectively adjust the temperatures. This not only optimizes home comfort but also helps prevent limescale accumulation.
Focus on Temperature Adjustment:
- Heating Temperature: Be careful to adjust the radiator temperature, not the ambient temperature.
- DHW Temperature: A lower DHW temperature reduces the risk of calcification.
DIY: Replacement of Shower Filters and Heads
Discover how to easily replace the aerator filters and shower heads in your shower to prevent limescale buildup. This simple maintenance can avoid overheating problems and difficulties in removing filters, ensuring the proper functioning of the Euroterm SIMPLEX 20 P boiler.
Boiler Safety During the Holidays
It's crucial to take some precautions with your Euroterm SIMPLEX 20 P boiler before leaving for the holidays to prevent accidents and problems. This also applies to the latest generation boilers.
Preventive actions:
- Close the main water tap to avoid unexpected leaks.
- Shut off the gas to increase the safety of your home.
- Turn off the heat generator to limit unnecessary energy consumption.
Once you return, reactivate the settings by following the steps in reverse. You might need to restart the heat generator to cancel the shutdown errors.
With these simple steps, you can enjoy your vacation without worries, knowing that your boiler is safe and well managed.
Boiler Usage Warnings
To ensure the safety, efficiency, and performance of the SIMPLEX 20 P appliance, annual maintenance is crucial. It is highly discouraged to intervene inside the boiler without adequate technical skills. In case of anomalies or malfunctions, it is important to always consult a qualified technician. Annual maintenance by specialized personnel is essential for the safety and continuous functioning of the appliance.
