hot water system for cricket club. Ideas?

[jasontheplumber]

Any ideas on a hot water system for a cricket club? They need:

Hot and cold water to 4 mixer showers
Hot and cold to approximately 5 other outlets.

They are having an LPG boiler put in to provide the heating and to heat a cylinder. (possibly)

Very tight on headroom for a gravity fed installation, and the mains pressure to the pavilion is 9 litres p/m.

Anyone got any variations on traditional gravity fed system with pumped showers?
Any ideas most appreciated.

Are you a plumber? Because you've described the pressure in l/min. That's the flow rate.

You may need to talk to the water supplier about the mains supply if you want to avoid storage tanks.

Meant Flow rate, apologies, long day.

Not averse to tanks, and its on top of a hill, in a small village a long way from the main road - if you can call it that. But will take advice from local water supplier as suggested.#

Not sure about that, might be a bit out of my comfort zone! WTF!

A PUK- Variboost 3-60 invertor driven unit connected to a 300/L Mc Donalds Plate flow.
Nice piece of kit for £935. All plug and play!

On a 50 gallon tank with 9l/min.

You been on the wine again Norc?

What do the shower valves require in l/min are you going to use flow restrictors? What are the other outlets?

 

[Norcon]

Would need doubled x2.

 

[jasontheplumber]

They currently have four electric showers which get beaten to fook by ham fisted clubbies. Any improvement on that shouldn't be too hard, flow rate doesn't need to be spectacular, and hadnt got as far as flow restrictors, still deciding on a suitable system.

Never heard of the stuff Norc is suggesting. They want a shower, not a nuclear reactor.

 

[Norcon]

That's off the shelf plumbing kit.
Childs play.

 

[jasontheplumber]

Whats a 300/l Mc Donalds plate flow? Or is this some elaborate wind up?

 

[Norcon]

No wind up...

How does 9L/min connected to four electric showers work?

 

[jasontheplumber]

Badly apparently.
