shower pump advice

[T & H Plumbing]

On a job and the customer wants Thermostatic mixer showers the shower room I'm fitting it is up 3 flights of stairs and the system the cold pressure is very good and the hot no so good I know I need a pump but I'm not sure on which one to get, ideal I'm wanting to fit the pump as close to the shower as possible as the cylinder is far away and having to run a pipe from the cylinder isn't possible so is there anything I can buy that I can connect to mains cold and hot supply so it equalises the balance coming out then able in me to connect to the therm mixer shower

What about the Trevi Boost, using the venturi principle

It looks like a standard shower with a huge price tag but it uses the power of the cold mains to increase the hot flow

Ideally pumps should be pushing the water from the cylinder to the shower and not pulling it from the cylinder to the shower so it should be next to the cylinder, the warranty may be void if it is not

Have you had the elec shower convo, i find showing them a couple of nice ones helps as most people think of their grannys old shower that used to be white and is now yellow

Salamander esp model its neg head pump that will do it

still needs to be at the base of the cylinder though

It can be above it as long as it's off an Essex flange with anti gravity loop it does have to be within 4m

That's a no no no , I'm not piping up thru 3 floors and other end of building take me weeks would a digital shower be a better option? I'm sure I've seen ones that have there own box where the hot n cold mains go into it and water is pumped out balanced any ideas?
