Hello all
I've read lots of posts, the things that normally get asked I think I can say up front...so looking for an opinion on whether it will be worth installing a second shower in a new bathroom (which will become the primary shower - the electric one will be for the kids/backup).
So - for the background.
We currently have low flow rate to the house (40m pressure, 5 litres per minute flow), but not to the stop-tap outside where it is 45 pressure, 20-25 litres per minute. Should have known really as there is a laundrette just up the road. We've got old lead pipe from the street to the house with jammed internal stopcock, so this looks like the culprit.
I've had a man around to quote replacing the lead main from the road to the house (with 32mm plastic pipe) which will be routed up through to wherever it needs to go. It's going to be moled (I live in a Victorian terrace) under the front steps and into the porch. As an aside, can I check that moling is essential?
The old lead pipes will be capped off. As an aside, I don't know if these are worth anything.
So once I've done all of that...the boiler upstairs is a Ferroli Modena 80, output is 24kw, which I understand would give me 9 litres of hot water per minute (I only think I understand this - so if anyone thinks that is wrong please let me know). So presuming the flow from the street stops being the problem (if I'm only getting 5 litres of cold per minute now, presumably that is all the boiler can get) - the next restriction is the capacity of the boiler.
Is the output from a combi that size enough to better what a 10.5 kw electric shower would manage? Or am I looking at changing the boiler as well?
Thanks in advance
