Hi all.
Firstly sorry if this is in the wrong section, but the title suggests it is a little bit of everything.
Right, I've been asked to help a good friend with a loft conversion on his fist floor two bed massioante. The work I have been asked to do is to rip out the old heat only boiler and change it for a combie. Along with the plumbing for the loft which consist of a toilet
Shower and basin. (just for info) There is also an existing bathroom which has a shower, bath, basin and toilet.
I've measured the incoming main pressure (static) at 2.1 bar and a flow rate of 12l/m. The mains coming out of the floor at the ground floor level is only 15mm. I was hoping for more as I would need to provide hot water to two bathrooms. Along with converting all the cold outlets to mains which appear to be run in 15mm copper. I can see this being a pottenial issue.
So the questions are is there a way to increase the flow rate? Which would then enable me to put in a bigger Combie. He's not up for digging a new main, so I've been looking into accumulators but don't know enough about them.
Would I also need to up the cold water pipes sizeing to the out lets? Would it make any difference? as I will now have the whole property on the mains and many different outlets competing with one another.
Thanks.
