Hi, I have had a full CH system installed in my bungalow Baxi Duo-tec Combi 28HE + 7 rads in a day and am concerned that some corners have been cut.
The boiler sits in a cupboard in the centre of the bungalow. A ll pipework runs up to it from under the floor and to my mind is the high point in the system. I asked whether Automatic Air Vent Kit 720004701 would be fitted as recommended by Baxi and was told it was built into the boiler.
The PRV is connected directly into a plastic tundish which is immediately T'd with the condensate pipe. This then runs for some 6m under the floor utilising what looks like 22mm Hep2o pipe. Baxi says that runs over 3m should use 32mm waste pipe.
I don't know if the system was flushed. I'm fairly certain that the drain valve on the kitchen rad was not used. Is it possibble to flush the system using the condensate pipe?
The heating and hot water work as expected but the boiler "roars" to my ears (certainly compared to Viessmann and Worcester boilers I have heard) , but am told I won't hear it when I put a door on the cupboard. Also when you fire up the boiler from cold there is a loud whistle which does go away after 10/15 minutes.
Am I unnecessarily concerned? I have photos but don't think I am allowed to attach them. Any guidance would be appreciated.
