Locknivar Noble Firetube combi not heating water fast enough
We have the Locknivar Noble Firetube combi boiler and it is taking a long time to heat the water (going to the taps). We have well water which is cold. There is also a mixer on the system that adds water from the well to the hot water coming out of the boiler. I would also say the exhaust is pretty loud. If you are standing outside anywhere near the vent it is very noticeable.
Has anyone else noticed the slow water heatup?
