Advice-pump for shower!

Arcadia1

Hi all, Ive been working on a wetroom and it's now time to fit the shower system in-Ive gone for a mixer shower but Im aware that, owing to the distance between my hot water supply and the shower location, Ill have to fit a pump.
Problem is that I will likely have to fit the pump in the attic space, above the level of the immersion tank, as the tank is located in a press under a flat roof, and the logistics of situating the pump at the base of the tank and then plumbing up into the attic and on to the bathroom are kind of awkward.
The cold water supply has plenty of gravity though.
The shower system Im fitting requires a minimum of 1 bar pressure.
Which pump should I be considering?
Kind regards
J

I would not stick a pump in the attic space. what you are doing is the equivilant of letting a man run a 25k race and then giving him a lift the last km...absolutly no point.

It will have to be fit lower.

Thanks for that, I suspected it made very little sense though Im being promised by merchants that it would work. Could you recommend a good brand,or type, with sufficient power?

Monsoon is about the best. You will buy a cheap version of monsoon on line called stuart turner however it will not be covered by an irish warrently the irish company wont even repair it.

Another reasonable pump is salamander and grundfos own and operate this brand in ireland so its reliable

Thanks Joey, much appreciated.

Monsoon would be about the best out there.

I had a Grundfos 3 bar pump installed on the floor of the hot press.

I converted to a solar panel system,so space was very tight,but managed to get the pump in beside the solar tank,and just barely enough space for the door to close properly.
The grudfos 3 bar pump works the rainfall shower in the ensuite.Some serious whack off it too.:)

Just be aware...The standard house cannot fit a 3 bar pump to its standard cylinder...

Standard cylinder fitted here Joey-there will be at least 12 yards for the hot to travel from pump to shower head. Will the tank simply drain too quickly with a 3bar? I have excellent cold pressure. Does it make sense to fit a new, larger tank or go for a low pressure pump?

On a standard house only 1,5 bar is rec. weather it be positive or negative. If you want to go 3 bar you are looking at a new cylinder.

A 42x18 or indeed 60x18 supply and fit will work out 1000-1200. The 3 bar pump will be 800 euro for a good model so tbh if you are going 3 bar you may not see change out of 2.5k.
