Hi I just trying to find out if the water pipe inside my house it's bigger than 15mm " 2 years ago I replaced my combi boiler for a new one and I think they fit a 32mm water pipe.

Can you identified the water pipe on this photos and let me know the size!!! if possible.

Many thanks

Those dont show the water supply pipe to your house.

The boiler connections seem to be the usual 22 mm for heating and 15 mm for water !

What are you trying to achieve?

The 22mm pipe 3rd from right which reduces to 15mm is the cold water in to the combi, the 15mm second from left is the hot water out to the taps.

Yes, we realise that but why?

I am fitting a second bathroom on the 4rd floor of my house and my water pressure it's only 1.6 bar and I've been told that I won't be able to run 2 showers at the same time with my combi boiler.

Regardless of mains pressure or pipe size to combi you will struggle to run 2 showers off a combi at the same time

A combi boiler can only heat a limited flow of hot water.

You have not told us which model you have!

The standard combi is 24 kW and can heat about 8-9 litres per minute. Thats enough for one shower but not two!

If you really must run two showers at the same time then you need a storage cylinder and that will have to be backed up by a lot of storage.

If you have a good mains flow, say 22 li/min or more, then an unvented cylinder is the answer. That could be heated by a 24 kW combi boiler!

I am quite confuse but my boiler is a worcerter 42cdi
I though having a 32 mm pipe on my house will resolve the problem!!!

What you think may not be the actual situation!

To run two normal showers you will need a dynamic mains flow rate of say 22 litres per minute.

Your boiler will run 1.75 showers if one decided that you need 8 litres per minute in the winter.

Of course there are many different showers and they can be adjusted differently.

So if you have adequate mains supply then you could probably run two showers at the same time ( just ! ).

A 42 kw HE boiler will deliver about the same as two 24 kw SE boilers, and I have never heard anyone say you can't run a shower off one of those.
