Hi
I am after ideas....I want to create a new bathroom but need to relocate the hot water cylinder which is currently in a first floor cupboard. The logical place to put it is up in the loft where there is plenty of floor space but not much headheight - apex about 5 foot. There is currently a water tank and a header tank up there.
I want to end up with a good strong shower, maybe boosted by a pump if necessary. What combinations of cylinder, water tanks and pumps would achieve what I want? I am confused about vented and unvented options, horizontal or vertical cylinders. My mains pressure is pretty good. I have a regular boiler, not a combi one.
Any ideas?
Thanks

Putting cylinders and the likes requires the floor to be strengthened as well as a working floor space and access ladder.

An un-vented cylinder or thermal store is the best combination provided the mains pressure and volume is good.

Pumps in lofts I'm dead against as they can be noisy, and I doubt you could store enough water anyway.

would the pressure be affected by raising the vented cylinder to the loft?

Very much so.

You would hardly get any pressure

Thanks for that. I will have a look at unvented options then and a structural guy to assess the strengthening.
Not a problem re the shower pump - that would be staying on the first floor...yes, I know what you mean about the noise

If you go the un-vented route, you cannot have a pump, and shouldn't need one.
