Unfortunately the courses are very much in demand at the moment. We can accomodate around 25 people on the course, but the courses are becoming fully booked earlier and earlier. Even though there are still 3 weeks to go, we were fully booked as of yesterday. We have decided to decrease the interval between courses now - to decrease the waiting time. There are still places available on the 14th July and 11th August, but we would recommend booking at least 4weeks in advance to ensure places are still available.
The 58mm tubes produce 50% more heat than the 47mm tubes (based on the additional area - the tubes are a fair bit longer, and wider). So a 30 tube 58mm panel will provide the same amount of heat as 45 standard 47mm tubes. The downside of the 58mm tubes, is that they are more fragile, and we have not found a good way to ship them (unlike the 47mm tubes, which we can ship to customers relatively easily) - so they are best collected, if possible.
The BS3 is ideal for your application. There are two relay outputs, the first operates when the panel is hotter than the cylinder (within the parameters set by the user), and once the tank has reached it's limit temperature (assuming you tell the BS3 to do this), it can divert by operating relay number two, which can be set to drive another pump/solenoid valves etc. If you wanted to, you could even cool the cylinder by turning on the existing boiler pump, which will effectively extract heat from the cylinder via the boiler coil, but you will need to relay the boiler contro to the pump, otherwise it will turn on the boiler at the same time.
Apologies for the mistake on the pricelist. You can price the thermal store by adding £270 to the VENTED cylinder prices. I have corrected the mistake! The price would therefore be the lower one ie. £440+£270
You can fit a second extraction coil ie shower coil and thermal coil to the same cylinder...assuming that the cylinder is physically tall enough. I think you would need at least 1500mm high and preferably 1800mm high, to ensure that there is space for all coils in the cylinder. However, if you want to drive the shower, there is no reason why you should not use the thermal store coil.
We can fit any number of input/output coils into a cylinder, as long as there is physically room available. It is possible to cheat with very short cylinders, and intertwine two coils, which is sometimes done with woodburner/boiler coils, for example

Can you tell me if there are any places left on the 22nd June solar installation course?
Also I looking into buying a complete solar kit from you but before I make the final list I have a few questions.
On the first installation roof space is tight so the preferred 2 x 20 tube standard panel is too tight, how much more heat energy does the 58mm tubes have compared to the standard 47mm i.e. is the 30 tube 58mm panel equivalent to 2 x 20 tube standard panel? I'm looking for an "over powered system" due to wanting to heat (warm) three rads in the summer (bathrooms etc).
Regarding the need to turn on the central heating pump can the BS3 control a second pump at a set temperature?
It looks like I'm going for the thermal store cylinder 210ltr, on your price guide it says that its £440 + £270 and then a bit further down its thermal store tanks, prices as for unvented + £270 which makes it £1090 + £270, can you confirm which on it is.
Again about the cylinder, is the option to have a second shower coil only available on the standard cylinder or can a second heat exchanger be fitted to the thermal store cylinders.
Many Thanks
