Took me weeks and weeks but I installed a direct hot water vented system from scratch in my house. Had never tried anything like it before but with reading posts on this forum and hours and hours of youtube videos I managed to get it up and running.. only thing is I'm worrying now I might of made a mistake.
The hot water cylinder is on the ground floor and the pipe runs up 2.4m to underneath the first floor.. I thought that the joists underneath the first floor had enough holes and notches in them already so was worried about making any new ones so what I did was route the pipes parallel to them (for about 2 m) and then up into the bathroom (just above the floor) to feed the basin and toilet. I then ran them horizontally in the bathroom for about 60cm and then back down to run them horizontally 2m in the opposite direction in between the next joists along before going up to feed the bath and then up into the loft to the cold water cistern. The cold water is all fed off the mains.
I started to worry that the hot water pipe that's vented up in the loft should have a continuous 'upflow' to the cold water cistern up in the loft. I used 22mm copper pipe throughout...
Any advice to a worried amateur would be much appreciated? I've tried searching the forum but haven't had any luck finding an answer.
Thanks
