hi all,
I'm facing an issue with my Navien combi boiler CH-240. It provides both heating and domestic hot water with no problem.
However, when heating is turned on, the navien keep igniting. It will ignite with a "woof" sound and you see the fire burning inside, and then after about 15 seconds you see the fire went out for half a second and the ignition goes again with a "woof" noise. This will keep going for as long as the heating is on.
this is not an issue when DHW (shower/kitchen facet) is turned on.
I'm thinking there might be some flow issue with my heating where the water flow is limited by the scaling of the water.
What could be the issue?
Thanks guys in advance, any comment is appreciated!
