Mira Shower and water pressure

[jfitzsimons]

Hi

Had a Triton t90i (8.5kW) for a number of years but recently it packed it in. Went out and bought a Mira Sprint (9.5kW) and installed it but now only a trickle of water when I turn it on!

From reading around it looks like I may need a pump as my tank is in the attic about 1metre above the shower (the installation book refers to 7 metres required!). Although the bathroom tap runs from the tank and there seems like lots of water pressure.

But why did the Triton t90i not require one? Will a pump resolve the problem? What pump rating would I need (water tank is not huge!)? Has anyone else had this problem?

Cheers
John

Electric showers are normally installed on the mains supply. A tank feed will not be adequate unless the shower is specially designed for tank feed. I don't think the Mira Sprint is. However the Mira Elite is suitable for tank feed, as is the Triton T90si. These showers have built-in pumps.

As chrishutt says, the Mira Sprint is designed for mains supply, whereas your old shower was designed for a tank supply, so you haven't replaced like with like.

thanks. that makes a lot of sense. the store i bought it had it listed as a "gravity" shower i.e. can run from tank but didnt state that the tank needs to be 7metres above the shower!! think I will get a mira elite II. Assume this is the best pumped shower around?

If the shower is fed from a tank supply, have you considered a mixer shower that gets its hot water from the cylinder? Cheaper to run and less to go wrong.

Yeah its source is a water tank. I have considered a mixer but then I would need to get hot water plumbed in plus would need hot water when I want a shower. I like the flexibility of electric showers, esp in summer

Try the Mira Advance. We've had ours 10 years now - other than the hose wearing a bit - great shower
