Hi all,
I'm in the process of needing to upgrade the hot water system in my house. I have a 15mm feed rising in the house, about 24l/min of flow and about 4.5 bar of pressure with the taps running inside. There's currently a small vented cylinder to feed three bathrooms so there's about 10 minutes of total shower time before the hot is exhausted.
So far I have seen four plumbers who have recommended completely different solutions, but the clearest contradiction is that two have told me to upgrade the main, and two have told me to get an accumulator. Of the two that told me to upgrade the main both looked at my water meter, one told me I had 15mm from the main and needed to upgrade the whole feed and one told me I will have 25mm coming in and only need to upgrade the bit that goes from the street to the house.
Thames Water can't tell me what the pipe size is to the meter (they told me to ask a plumber, which is where the whole problem started!), and the meter itself is a plastic affair that fills the entire hole so I can't see the incoming pipe at all. Is there any way that I can find out what I'm working with? I'm completely stumped and don't have the confidence to go forward with any approach at the moment!
