Hi, I have another query with regard to my own plumbing this time that
I would like some advice on please. We are building an extension at
the moment and need to run water from the current house into the
extension. Without going into all the reasons why, I am considering
upgrading the gravity fed hot water cylinder to a pressurised one.

The cost of these cylinders in the UK seems over the top, but a friend
recently told me they were much cheaper in France & he had a recent
Brico Depot catalogue to hand. A 150 ltr cylinder costs 99 Euros
fitted with a 1800w immersion heater, a 200 ltr is even cheaper at 90
Euros! I understand that these do not have a coil inside them so I
could not hook it up to my existing C/H system. This does not bother
me, it does not seem to cost much more whether I heat off gas or
electric from past experience. According to him, you just plumb them
in, connect the water pipes up and away you go.

Has anyone any experience of fitting these things & can offer any
advice?

My questions a

Will these tanks fit up to my existing 22mm plumbing connections OK ?

Can anyone forsee any problems modifying my C/H system as the pipes
won't go through the HW cylinder any longer ?

Would I be breaking any regulations and/or should the building
inspector be involved ?

Do I have to fit a vent pipe (think I do)?

Can anyone forsee any other problems ?

Thanks,

Peter
