Hi, I need to get a LPG water heater to run 4 showers and 8 basins, the basins are in a ladies and gents toilets, any ideas what boiler I would need, I've used the Britony 2 C&M for most installations but I thought it may not be man enough for this set up. Any help appreciated.

Makes you wonder why we bother getting qualified
never mind fellas, you obviously dont know, I'll phone some suppliers tomorrow and ask them. Hmm whats DIY stand for again....
Get a 300 litre unvented cylinder heat the coil by 40 kw combi run the cold mains through the combi into the unvented cylinder take output from output of cylinder.Howzat.
I put a 900 litre cylinder in a similar job, with 6 showers and 4 basins, but the customer has stated a LPG boiler on this occasion. This is a portable 21 foot container BTW.
i cant tell if thats genius or **** taking
.but seriously would that work?
i think not but am prepeared to be wrong with an explanation.
I wonder if you ask such naive questions if you really understand the design criteria involved.
What hot water flow rate do you require?
What mains flow rate do you have available?
Is it acceptable to have stored hot water and drain everything before moving the container?

Well, I wouldn't be posting on a DIY forum if I fully understood the design criteria, the flow rate required is enough to run four triton mixer showers, the mains flow rate is gonna differ from one site to another, this is a portable container. And if hot water is stored, it would have to drained for transporting, but I'd rather not have stored water at all, thats why im here popping the qusetion.
Thats what I expected!
If you are unable to even set basic design criteria then its not possible to come up with a workable design.
This kind of thing is not cheap to install so its best to get it right at the beginning rather than that take some DIY design ideas which will not work.
I would suggest that you decide exactly what you want and then employ a consultant.
You said there would be SIX showers but now you only say that FOUR are required to work together. And what about the FOUR basins? Do you want any of them to be able to work at the same time? Do you want to be able to flush toilets while showers are in use?
If the showers use say 8 li/min each then what do you do if the mains supply can only supply 12 li/min ???
Do you expect the showers to run FOUR continuously all day long? Thats a mains supply of 32li/min plus the basins and toilets.
That needs 80 kW of instant water heating. That will need a second trailer full of LPG cylinders or better still a full size road tanker if its to run 24/7 at a pop concert for a week!
I think that you need to go back to the beginning and decide on the basics!

The trouble is, the container is going to be moved around during its working life, your guess is as good as mine as to the pressure of the mains, Surely there is a boiler which can easily run this system, say on the average mains pressure.
