Hi All.
We currently live in a 4 bed house which is going to be extended to a 5 bed, 1 bath & 1 shower. Now the current boiler is a 34cdi. Cold water pressure is good, I dont know what people count as good, but I dont suffer from low pressure etc, the pressure is adequate. At the moment, in the bathroom if the basin tap is opened, and the shower tap is on, the pressure drops drastically.
However if the kitchen hot water is on, the bathroom one is only slightly affected but still gets good hot water. So I dont know what to make of it.
As part of the extension, below is my requirement/some facts.
Thanks in advance.
I attach the proposed floor plan.

As part of the extension, below is my requirement/some facts.
- The old lead pipe will be upgraded to a plastic pipe, say 32mm or the next size down.
- I prefer Combi as I dont have where to put a mega flow tank/pipe work etc.
- The only time the showers will get used is in the morning, small chance of 2 getting used at thesame time. and even if that was the case, it would not be for long, say 5 - 10 mins max.
- I plan to have underfloor heating on an area of about 60sqm, if I only do the centres i.e in a ktichem lets say 50sqm.
- During the day after the shower period, omst hot water demand is from the kitchen/toilet basins.
- We previously had a system boiler before combi 3yrs ago, so I have a feeling some of the pipes were not correctly sized, also the heating engieer cut corners, for example the boiler is located in the kitchen, and the downstairs bath/toilet is next to it, only a wall seperates them, however the pipe work is such that when the hot water is opened, it uses the old system boiler pipe route, so the water goes up to the first floor and then comes back down, even though the demand is from the adjacent room where the boiler is.
- I have read on here that one can have a combi + a cylinder. I like the idea although I want to know if the cylinder ought to be upstairs or downstairs or it doesnt matter.
- If the cylinder + combi is the way forward, can someone please advise on who should be placed on cylinder and who should be direct from combi.
- The proposed extension is such that the boiler is intended for the new utility room which is downstairs, where it says bathroom downstairs in the picture floor plan below.
Thanks in advance.
