Thermal protection for solid fuel boiler 3/4" 125°C 5067.20.000

Thermal protection for solid fuel boilers

This reliable protection is designed for heating installations with solid fuel boilers, especially those without a built-in cooling heat exchanger. It provides protection against overheating, which is crucial for the safe and efficient operation of the heating system. It complies with PN-EN303-5, which confirms its quality and compliance with stringent standards.

Construction and operating principle

The protection consists of several key elements that work together to provide effective protection: a check valve, a pressure reducer, a thermally controlled filling and venting valve, and a temperature sensor with a capillary. With this solution, if the permissible temperature is exceeded, the boiler is automatically cooled by the flow of cool water from the installation. The reducing valve is connected to the water supply network, and the venting valve drains hot water from the heating installation.

• The check valve prevents water from flowing back from the boiler into the water supply network.
• The pressure reducer stabilizes the water pressure supplied to the boiler.
• The thermally controlled filling and venting valve regulates the water flow depending on the temperature.
• The temperature sensor with a capillary monitors the boiler temperature and activates the cooling mechanism if necessary.

This comprehensive solution is for installers and users who value the safety and reliability of the heating system. Installation is simple and intuitive, and operation is efficient and smooth. Using this protection can avoid costly failures and extend the life of the boiler.
