I have got to spec and price a job which I could do with some advice on. It is for the clubhouse of a sports club.

Basically there is currently no heating, and an open vented hot water cylinder off an immersion heater.

What they want is heating in the bar and kitchen area and a new hot water system for new showers etc.

At one end of the building is the kitchen, ladies toilet and the bar area. The gas meter is down in that end of the building as well. At the other end is where the mens toilet, dressing rooms and showers are going to be. There will be 6 showers, and two wash hand basins in total in the mens and changing room area.

What I had in mind was a combi boiler in the kitchen to do the heating in the bar and do the hot water for the kitchen, bar and ladies toilet. Then an unvented set up for the showers and mens toilet area. A direct one may be better due to length of pipe run from the boiler to zone the cylinder and heat it indirectly. I have never fitted a direct unvented, are the recovery times any good? This is only going to be used on a Saturday, once a week. So need to weigh up installation cost against running cost as it wont be getting a lot of use.

What kind of size of cylinder am I likely to need? Thinking an accumulator will be needed as all 6 showers are likely to be in use at the same time.

I have only ever done work in domestic houses, are the any different regulations involved on the water side of things for a sports clubhouse type place?

Any advice would be a massive help.
 
i like the idea for combi for kitchen then accumulator to feed THE indirect hot water cylinder

for six showers you will be needing not one but possibly two 250L or 300L + accumulators will need to be 2 x 500L (as accumulators only hold 60% of its volume with water
 
so I will sugest 30KW combi and S plan one zone will be heating another one will be UHWC
 
matt what is the flow and pressure at the moment ? high is the showers compare to place where the UHWC will be (just thinking of the pressure lost should you need to run pipe work up )
 
Flow is over 25 ltr/min which is all my flow cup goes up to. Didn't have my guage to check pressure, but it is VERY good. The building is all on one level.

I'm not going to have the room for 2x 300L unvented cylinders and 2x accumulators I don't think.
 
how much water do you think that 6 showers will withdraw per minute ? i would think round about 12L each as when public showers are used they are used full flow . So you will have 72L going out per minute so you need quick recovery and just thinking combi will not be a good idea as if they use water in kitchen boiler will not recover UHWC
 
From an installation point of view, direct unvented would be better. I just don't know how good the recovery times are on them. I have limited space as well, and 4 big tanks just wont fit. This is going to be a real pain to try and get right.
 
Just had a look at recovery times for direct units, they are a no go. Take too long. I am essentially sizing it for 20 people to be able to have a shower in the space of an hour, that is the worst case scenario really.
 
If I helps I looked at a cricket club once 6 showers linked to break tank feeding 2 48x18 indirects with 3 bar pump on outlets, tmvs gonna be a must
 
Tank, BCW, heatline 85tc and 2 800sl cylinders in a bank? Horrific cost! Amazing output
 
If you're restricted on the room why not go down the electric shower route?

To be honest, I didn't even consider this. It may be a bad idea, as I am struggling to see where I can site enough stored water.
 
Problem with electric showers performance will be pants and will fur up in no time, will need a massive amount of incoming power too
 
Watersofter soon sorts this and if it's a clubhouse I'd imagine its got a decent supply. But you're right, if not then it's expensive.
 
wall mounted combi to cover heating and kitchen/bar hots

shower area stick a 50kw instantaneous water heater on wall

can recommend Rada hands free showers, fitted 6 at my local gym, and I've got one left over if you wanna buy it for £50, over £300 in plumb centre
 
If 20 people are going to be using it in 1hr you need a lot of capacity from unvented cylinders as they wont recover in time, or a big water heater maybe Andrews. It might be worth giving them a ring I'm sure they will help you.
