 Posted: Tue Sep 11, 2007 5:12 pm Post subject: Help me make sense of my Rad pipework please!!! |
  |

Ok ... this is what I have - it is inherited from the previous owners when I bought the house and is based on visuals so I will explain best I can.
Got a Gas Boiler doing the CH and its pipework routes directly to the 1st floor.
There are a pair of CH pipes dropping down through a box but I am pretty sure they feed a Rad in the utility room. When I opened up the drain cock on that rad, it took a fair time to drain the system - much more then one radiators worth (got a total of 4 rads on 1st floor)
On the ground floor - excluding the rad in the utility room, I have a total of 4 rads. I also have 4 sets of downpipes, each set pretty near to a rad in three of the cases - does this probably mean that each downstairs rad is fed vertically from upstairs? If so, is this a good way to go? (I would have thought it would mean cold spots, air locks, etc to try and to get the downstairs rads filled would be a PITA?)
Of the 4 downstairs rads:
One is in the hallway and has a draincock
One in the dining room and has a draincock
Two are in the sitting room - one with a set of pipes very close going from ceiling into floor, the other where a set of pipes going ceiling to floor is on an opposite wall to the rad
Neither of these sitting room rads have draincocks - makes me wonder if a) they are possibly connected to hall rad and will drain through that, or b) the lazy feckers who installed it didn't bother to fit them on those two.
Now given the way I have described this (and please ask any clarifying questions) what would you make of the way this has been installed and given that I am having a new boiler and so draining down the CH system (hence the search for draincocks), should I be looking to improve this layout (I will be putting down some flooring over the floorboards in the near future so would not be totally against lifting some boards and rerouting pipework first if it really would make a difference (it could also potentially mean I could lose two ugly sets of downpipes in the sitting room at least).
TIA

its really difficult to tell how its been plumbed... sound like you may have a drop system, by the number of drain offs.
There may be upto 3 rads from each drop.
Have a chat to the corgi guy when he comes on friday.

Will do - He likes to work on a day rate so want to make sure he will not be suggesting stuff to keep busy 
Are drop systems ok generally? No reason to change just for change sakes?

nope, no need to change the pipework, or layout if its been working ok.
He should recommend a powerflush, to prevent any sludge/muck from old system getting stuck in teh new boiler!

cheers - I asked him about a powerflush in fact (think I may have read it on one of your posts  )
