What size water tank/s

[P.S.]

Have had a 2storey side extension built and to diversify the water feeds (rest of house on a combi) was looking to install cold water and immersion heater tanks to feed the that side of the house.

It will need to feed a new en-suite bathroom (shower, basin, toilet) and a cloak-room toilet and basin

Advice needed on the size of tanks as the en-suite will be a power shower (1 - 1.5bar)


thanks in advance

 

[P.S.]

anyone ?

And any other recommendation for a quality, silent, pump and is 1-1.5 ok for a single shower

I would feed all the cold outlets off the mains except of course the shower.

Go with a 25 gallon tank for your cylinder.

As for the pump, the higher spec the better I would think.
