Yes they are, made by Thermomax in Ireland, Rick

yes paypal is fine but let me find it first, I will quot "it is in the barn" any that know me will testify that that is an enormous undertaking on its own, Rick

well I found the controller, but unfortunately I have already stolen one of the boards to repair another (a while ago, I had forgotten) but more important I have no sensors I found my box of odd ones and there are no ringdales amongst them, if you look in google under solar controllers you should be able to find a cheap one or even ebay, what you are looking for is a solar differential controller basic, no display, so what with this and not being able to test the air bag theory it has not been too good a day, Rick

so today we have had a lot less sun, but still got tank full at 49 degrees, so thinking the plate heat exchanger is not up to the job, so going to fit a 6ft length of convoluted stainless steel pipe in the bottom of the cylinder tomorrow, just means that in the winter and on poor solar days I will end up with a tankful of warm water instead hotter water at the top, Rick

As Timbo says you have to use a neutralizer so it does not go bang in a power cut, unless you do the whole thing gravity but that would be a completely separate system, I can send you a diagram if you like, just PM your address, Rick

thanks rick i could really use some ideas for sorting my heating and hot water out .
any other tips or money saving ideas you might have
