hello could someone please recommend a model or internet site where i can find a good low energy pressure boost pump for my shower so it needs to boost the hot and the cold, 240v, i have a gravity fed water system with not enough head height hence the need for a pump. any advice greatfully received roger

What? you actually want to use more than three tablespoons of water to wash yourself? How dare you! Don't know know how tepid water is killing all the barramundi? Storks are falling out of the sky as you squirt water (at slightly over a dribble rate) at your body!

Oh    Roll Eyes  what a help.... 
Does Martin needs a shower or Rog ?

I just used an of the shelf one like stuart-turner  ones first , sure there must be more efficient ones ....,

But ended up with a pump with integrated pressure 25l tank and an additional 75 l pressure tank = pump starts just  occasionally and not always when someone flushes the loo or washes the hands

The tank is one of those http://www.pentairpumps.it/articolo.asp?I_ID=267

Pump one of those

But these pumps can stress your inverter (surge load) so perhaps you need one with less watt

yep after 5 years of body washing with a bowl of water now i would like to use maybe three bowls if i keep the shower quick,
thanks billy but the pump seems to draw 1.3kw thats massive! i was just looking for the type of pump that goes under the bath to boost pressure not to pull the water out of the ground i have a shureflow 24v for that, p.s have you started building yet?

You could try Screwfix for a bog (shower) standard booster pump.  Don't know the watts mind.

hey rog

no didnot start building  yet , we changed design and got new planning and retention for our log cabin  flyingpig

Anyhow , didnot know you have a pump already  is it the shurflo  deep well pump ?

So you pump it in a container and then use a AC 220 V pressure pump ?

....or get a decent thermostatic shower mixer. I have one from screwfix (the 'traditional' style bath taps/shower unit). It's very impressive - plenty enough water to shower, from a large shower head, which has less than 2feet of head for hot water AND it's mixed with the mains cold water feed.

If you use cheap showers, or narrow/small shower heads you'll get poor shower spray. Use a good quality mixer valve, and a large shower head and you won't need the shower pump.

billi yep its a shureflow 9300 24v and i have an english hot water tank this can be heated either buy backboiler unit in chimney flu pipe when the stove is burning or with an electric element inside hot tank later maybe next year i will connect up hot water solar panels so free hot water all year around.

Rog

I presume with  the "english hot water tank" and the backboiler it is a non pressure setup  Tongue

I was just asking because your shureflow 9300 24v  could actually  provide upto 7 bar pressure (depending on the depth of your well  )   so i thought a pressurized container and a control for the pump could perhaps work without an additional pump  , but that was just a thought and donot know the details of your setup

Anyhow  i had to in cooperate a small pump like that , because my solarpanels (with integrated watertank )  were delivered (wrong / not Navitron) as a not pressurized  so it didnot work  with the pressure coming from my well pump

Long story short   here is the pump i fitted as a booster pump from this producer  http://www.stuart-turner.co.uk/default.aspx?page=482  to get pressure ( but donot connect the toilet cause she will start and stop  and so on)

And we  offgrid people dislike start up loads  Tongue
