Gravity fed combi boiler?

[pipe strangler]

quote="tgreen1";p="835059"]Hi,



I think all I need is a cold water gravity tank with a pump creating a new feed to my current boiler (admittedly its a pretty basic 'Main 24kW' but it seems ok).

Correct. But that would only supply cold water to your thermostatic shower. you need an independent hot water source.

Accumulators are ridiculous in a domestic environment, no need.

for once bamber i agree with you

Interesting, though my shower isn't thermostatic at present - its just running off the taps from my bath. I may well decide to put in a thermostatic stand-alone shower instead if I am getting the work done.

So- if I keep my existing set-up (mixer shower running off bath taps) then a cold water cistern running to my combi boiler then to the shower is ok. If I put in a thermostatic shower then I will need a cold water tank AND a hot water cyclinder?

I have to say I'm put off of hot water cyclinders a bit. They seem like an awful waste of energy, especially when located in an uninsulated loft.

Big thanks again.
