The water pipes in my kitchen are copper pipes buried in the concrete floor without any insulation. I am hoping to redecorate the kitchen and was hoping to re-route the pipes so that I could insulate them. Presently it takes some time to get hot water at the hot tap.
To complicate matters I have a door on either side, so I can not run pipes horizontally along the walls without hitting a door.
What is the group's opinion on the best way to run the pipes?
I could dig up the floor and bury new pipes in lagging but that sounds like a messy job.
Another option is to box them in at ceiling level above the door. After the door I could continue at ceiling level or drop them out-of-sight, behind the kitchen units. I think boxing could look ugly but perhaps in bathrooms and kitchens you can get away with it?
My other idea is to pass the pipes through the joists in the ceiling above. On the plus side, the pipes would be out of sight, except for one drop in the corner. But I fear there are disadvantages. The boiler is in the middle of the kitchen and the bathroom is above. So there are already a lot of pipes going through some sections of the ceiling and the ring main also passes through those joists, so there is not a great deal of room left. I could run the hot water pipe through but I think I would have to leave the cold water pipe in the floor.
If I did go through joists, I would have to use plastic pipe. Some people claim copper is better as it is antibacterial, so I wonder if copper would be better for hot water?
TIA for your opinions
