Thank you, I will place the lap vents later this week. I also wonder if my laundry air dryer in the living room is not making matters worse. I have ordered a deshumidifier for laundry that should r duce the house humidity level.

Can't fix issue of my Worcester Bosche combi 25i. Since I moved to my new house back in February, I noticed that the pump kicks in every hour or so and the flow can be heard especially in the heaters upstairs. The flow runs for around 3-5min and then stops, the boiler itself remains silent. I...
