300 litre Cistern has 15mm pipe to supply power shower .

Hi All

I have job to do .

Hotel has 4 cisterns x 300 L water each cistern supplying two rooms with electric power shower 8.5 kW power that need to have min. 8m/min water flow .
Power shower no heating water.

Flow rate is below 7-7.5

No chance for pumps because system is complete mess .

So what I think is better solution to change from 15 mm that supplying rooms 28 mm from cistern to the point where pipe going to the ceiling which will be around 1.5 m .

So 1.5 m 28 mm and then 15 mm to the room .
What do you think ????
Is that wip

It's a gravity fed electric shower it only requires a cold feed

I've also fitted a pumped electric shower before. The pump and 8.5KW heater are both inside the unit. Worked a treat in a similar situation but yes, very noisy indeed!

Mira elite 2 is one example of a cistern fed electric shower. Noisey buggers indeed.
