The SELTRON HC oil-fired condensing boiler is the ideal solution for anyone who wants a reliable and efficient heating source with a maximum level of comfort. Modern oil condensing boilers provide high efficiency by additionally harnessing the energy of flue gases, making them particularly suitable for heating renovated buildings as well as new constructions, as they work perfectly even at low heating temperatures.

Knowing that a great boiler alone is not enough to keep your heating system running well, we've built the SELTRON KXD20, a high-performance controller that combines the functionality of a boiler controller with that of a weather-controlled controller, into the SELTRON HC oil condensing boiler. The KXD controller ensures that the boiler operates correctly, can regulate two mixing circuits based on ambient and room temperature, and provides domestic hot water. 

With the optional GWD module, you can also be informed about the boiler's operation via your mobile phone or tablet using the CLAUSIUS app.
