Hi All,

I am looking for external dimesions of a panel for my architect to use in plans?

I am planning on using a 210 litre cylinder and am in the south East (panel will be mounted due south), i beleive that a 20 tube 47mm panel will do the job, but would a 30 be better?

Anyway, whichever you would recommend, has someone got full external dimensions?

Regards,

AB.

I'm sure someone who knows properly will be along in a while, but in case not:

My system, installed by one of the installers on the forum, is a 20x47mm with a 130 litre cylinder. It hasn't overheated (yet). On this installer's website, it says "a single panel is sufficient for a 175 litre cylinder" (and I think that might be a 20x58mm panel). So indeed I reckon that you should go for something more than a 20x47mm.

I can't get the Navitron homepage from here at work (pretty certain not due to anything at my end). So I can't look around for the dimensions of the panels. Still, provided the website works for you, then you can look yourself. Perhaps you have, and there's nothing there?

Hi,

Thanks for the help, looks like i will need a 30 tube then...

I can't find anything on panel dimensions, i can find the length of the tubes and their diameter, but i need full external dims.

If someone knows where to look, please post a link.

Regards,

AB.

Hi

A 30 tube panel is approximately 2.3 x 1.6 m

If your household is more than 2 people go for 30 tubes. More than 4 2x20

Hi

Also see http://www.navitron.org.uk/page.php?26. Should give you more info.

I use a 20x47mm on a 172 litre and that works fine but is near the upper limit. CeeBee is right - for your application you definitely need at least 30x47mm on a 210l cylinder.

2x20 will cope with high water consumption but will definitely need a heat dump for periods when you go away for more than a couple of days .

AB,

Navitron recommend 6.5 to 8.5 cylinder litres per tube. When we install we work on less litres per tube, say 5.5 to 7.0 litres per tube - all these based on standard dia 47mm tubes. The dia 58mm tubes are also longer and give about 1.5 more power each. i.e a 30 tube x dia 47mm panel = a 20 tube dia 58mm panel. With a 210lt cylinder I would always go for a 30 x 47 or 20 x 58 panel - the choice depending on which fits your location best. This would work out at 7 litres per tube. 

Dimensions - see FAQ but are

                L            W                 H
10 x 47  : 1760    x      760    x   130mm     (LxWxH)
20 x 47 : 1760    x   1500   x   130mm    (LxWxH)
30 x 47  : 1760    x   2170   x   130mm    (LxWxH)
20 x 58 : 1900   x   1660   x   130mm    (LxWxH)
30 x 58  : 1900   x    2406    x   130mm    (LxWxH)
10 x 70  : 1760   x   1000   x   130mm    (LxWxH)
20 x 70  : 1760   x    1950   x   130mm    (LxWxH)

You have to add a bit at each end to the width because the above don't include the pipes - say between 120 and 150mm at each end - but for planning purposes these are the dimensions of the panel.
