Shower pumps letres per min and bars

Sterlingtimes

My present Mira power shower is specified as delivering 14 litres of water per minute.

I am having a shower pump installed in another room that is specified as 1.5 bar twin.

Is the bar convertible to litres per minute? How can I compare maximum water flow between the two?

As far as I remember bar is a pressure amount, how high can the water be pushed?

I would think you need to get the name of the shower pump and look up what LPM it can produce?

Put your hand under them & feel?
As Hasbeen says one is pressure & the other is flow rate, so I assume you'd have to know the length & bore of the pipework to compare the numbers. A bit like volts & amps, you need to know the resistance to compare.

The relationship between pressure and flow rate depends on the state of the pipes that lead to your home.

You could have a very good static pressure, but if the pipes are old and furred up, you'd only get a trickle when a tap is turned on.

Find the pump you are installing and then look on manufacturer website. An example below shows a 2 bar twin being at 35 litre per minute...
