    Hi all

    Currently have a Grundfos STL - 1.0c Shower pump, we live in a flat and have a hot water cylinder and cold water tank which are both below the shower outlet, this pump also pumps hot water to the kitchen tap and hot / cold water to the bathroom sink so it does alot of work!

    It seems to be slowly failing making awful noises and is probably a good few years old now so we are looking to replace it. Really just looking for recommendations on what to go for and what to avoid!

    Thanks

    Marc

    ST Monsoon, not cheap but it's a quality pump + 5 year warranty

    That'll do the job. Shop around though, you should get it cheaper than that. Just make sure to get it setup up properly and it will give you years of back stinging showers :sneaky:

    Cool thanks !

    Is this a DIY job? Had a plumber in today to do some other work and suggested could do it our selves but never done one before!

    How big is the cold water storage tank, as the stuart turner pump might empty the tank in no time.

    Good point should of thought of that! The tank is roughly 58cm width X 64 depth and 81cm high

    Sorry not sure how else to work that out!

    Sorry for silly question but what's best way of working the hot water out seeing as has a fairly thick layer of foam all round

    Measure the thickness of the foam and subtract from the cylinder.

    That's 3.142 x radius x height . In case you're as bad at maths as me :whistle:

    Just measured the cylinder, a tape measure all the way round it is 160cm and its about 80cm high - foam is about 3cm thick.. id love to work it out but will fail!

    Hopefully both tanks are big enough for this pump though?

    Thanks for all the help!

    Your cold water cistern seems to be 50Gal, so that should be fine.

    The HW cylinder would be approx - 160/3.14 = 510mm - 60mm = 450mm diameter. Chance are it's a 900x450mm cylinder which equates to roughly 120L - if it is a more unusual size of 800x450mm then it's closer to 100L.

    You may find that a 3bar Monsoon will empty that of usable hot water in under 10mins, shower head dependent.

    Unfortunately further consideration of pump or cylinder size may be needed dependent on proposed usage.
