Pay attention to the system pressure, kettling can often be stopped by raising the pressure some pounds and/or increasing water flow with a pump that can move more water. Having multiple zones can slow water flow when some zones are closed, A bypass pipe, so water can flow faster through the boiler can stop the kettling then.
