Hello,
We are in the process of redoing our bathroom, and I want to get the best shower that I can for my system.

We currently have a Combi Boiler (Worcester Greenstar 28i Junior) and while I had always assumed that the hot and cold water supply for the bathroom was from the mains, we discovered when we had the new boiler installed last week that the cold water came from a cold water tank in the loft (I don't know what size it is - i'm assuming just the regular 50 gallon tank).

To complicate things, we used to have an electric shower, but it blew up. It is still plumbed in to the mains cold water though. We currently have no working shower Rolling Eyes

So my question is, what sort of shower should I get for my new bathroom? One plumber I spoke to said I should stick a pump to the cold water tank and get a thermostatically controlled power shower (I think).

Another said I should just use the mains cold water supply and get a thermostatic mixer shower.

I'm worried about putting a pump in at all in a combi boiler system - but I would really love a half decent shower. What would you do?

Would really appreciate any responses at all as I genuinely don't know what to do.

Thanks in advance
Sybnpaul

Make sure pipes and taps etc are suitable and then do away with tank in the loft so that all hot and cold supplies are mains fed.

Regarding shower yes a thermostatic one but make sure it says it is suitable for combi systems - some are not!

Surely it as actually as simple as creating a link from the Mains Cold to the tank in the loft to the Cold feed form the tank and removing the tank.

Yellowman - yes it is BUT some taps are not suitable, or too old, to stand being subjected to mains pressure hence above comment.

I would have expected whoever installed the combi, presumably converting from hot water cylinder system, would have removed this tank. Maybe there was a reason for not doing so.

Hi
Thanks for your responses.

The general consensus amongst the people fitting the new system was that it might have been left up there simply because it was too big to get through the hatch, and the loft space it sits in is really tiny making it very difficult for anyone to actually get up there and take it out.

Thanks also for the advice - its a bit of a weird set up, so I'm grateful for your help.
