My open vent system boiler (ecotec plus 428) is a year old. It replaced an old back boiler. The system was fully flushed. The system is much more efficient (as you'd expect) but I have a very annoying problem.
The pipes underneath my bedroom floorboards are very noisy (a loud ticking noise, sometimes distant banging when the boiler is firing).
This wakes me up in the morning. My old system never did this, the pipes are the same.
I've read all the various posts and have some questions.
I discovered from another thread that if I set the water to come on AFTER the heating, very hot water wouldn't divert into the pipes and this made a dramatic reduction in tapping / expanding noise (to almost nothing) first thing in the morning.
I would like to try and stop the noise at all times (when the system is at temperature)
The noise may be due to pipe expansion against the timber floor joists, but it never used to do this. OK, the water may be hotter. It doesn't noticeably decrease if I reduce the water temp (69 degrees now, boiler set at 28kw).
The installer says there is Sentinel 200 in the system. If I add another litre is there a chance it will reduce the noise?
I can't easily lift the boards because they are stripped, and a stud wall crosses them (to create an en-suite) so putting felt around the pipes isn't really an option.
This morning the tapping/ ticking pipes happened again at 4.30am even though there was no demand for water or heat. The Boiler was firing, the water cylinder was hot even though it was timed to off. Any ideas why this could happen?
Any help welcome!
