Grehelpat stuff guys ah no worries was just your 12 volt finger  If you need a 350 watt pure sine wave inverter (good heavy unit)  , hope you go the 12 volt DC route , but if you need one for these Ac pumps  i sent it to you for cost of the parcel and then you sell it here (into my account then the dollars go , comprendre ) I think my Piano (tab) has been drinking Billi |

Got my 12v pump in the post yesterday [thanks dhaslam] now ready to start. The cunning plan is to have 120ltr twin coil cylinder sited with the rest of the stuff, to make it look as realistic as possible.
As I would like to produce some hot water to show to people, it doesnt seem practical to fill a cylinder and have a storage tank above. An idea that i am going to try, is to use a 10 ltr copper cylinder [taken out of a heatrae sadia over sink heater] insert a home made retro fit coil [cold fill from a ten gall. f&e tank]
Pipe the system in the normal way ie to twin coil cylinder, but "tee" off in a convenient place to connect to the retro fit, with valves in place to stop circulation to the solar cylinder. May try and disguise it so that people will think the hot water is coming out of the solar cylinder.
A bit of explaining will be required to "joe public", but important to see some hot water being produced.
Not ideal, but easier than carting round hundreds of litres of water methinks

Why bother with a retro coil at all - just use a simple direct system to heat the water. The punters cannot see that there is no coil in the cylinder.
Could you not have a dummy/scrap cylinder (hidden by copious extra insulation) which just has the small cylinder inside?

ericw, i think its important to have a double coil cylinder on show to explain to the punters to show how it works.
I could do as you suggest, but do not want to wreck a solar cylinder

I think the problem you will have is that with only 5 tubes you will never be able to heat a full sized cylinder - what you need ideally is a 1/4 sized one.
So could you separate the demo into two parts ?
Use the small heater cylinder and the panel to demonstrate solar water heating and the controller.
Get an old damaged non-solar cylinder (although I'm sure plumbers never have such things) , cut the side away and add an extra coil, so you can show the customer whats inside, in a purely visual "real life" mock up with the pump station etc.

Have got the demonstration set up working. Tried it out on Saturday when there was a bit of sunshine.
I think I will add another demo panel as one is not enough. Got the temp. at the manifold up to 45c but took a long time, would prefer a quicker heat up time for the domestic water.
May be a stupid question, but would it make any difference if there was a backing to the panel. My panel is just fixed onto studwork [3x2] so is open behind it. Thanks

step up to a "real" 10 tube panel.
