Hi Alan what be best power booster that I would require to fit under bath for electric shower and im not sure if I have combi or not ? Diy here willing to give this a shot

[@MadDog_Rules]

Hi Alan. Would the booster be suitable to fit to pipes that come from the floorboard, underneath the bathtub? Also how much space does the booster need in order to not overheat? I have a mixer tap with shower hose attached and this power booster is suitable for that? Many thanks and appreciate any feedback.

This blog explains the fitting of a SPB under the bath :-

A SPB does not need space around it but stop it from touching the floor as it might cause vibrations and you can wrap it in bubble wrap if you wish (they do not overheat)

Hi, your diagram shows use of 2 pumps with both being gravity fed. What if the cold is mains and the hot is gravity please?

[@alandwright2]

The best thing to do if its mains pressure cold is to double boost the hot with a SP21S:-

@@alandwright2 Thanks for the reply. There is room for one under the bath, two might be difficult I think, so I will try with one.
