    Couple of newish (few years old, but haven't been run in a system) Riomay DF120 evacuated tube solar thermal collectors available for collection from a relative - West Sussex. £100 each, in good condition, but without packaging.

    http://www.riomay.com/app/content/docs/Riomay_Solar_Thermal_Technical_Details-web.pdf

    These are quite nice direct flow panels which feature a higher than typical efficiency, and can also be installed on flat or very shallow pitch roofs (most evac tube ones can't).

    Drop me a line at tim at seoss dot co dot uk if you're interested. Will edit/delete this post when taken.

    Also have a Gledhill 300 ltr unvented cylinder available to go with it, for £155. Various different arrangements possible, but an easy option would be to use the two together, with a flat plate heat exchanger (circa £40) in a 'side arm thermo-syphon' arrangement (the solar circuit is still pumped in this arrangement which leads to very good stratification).

    n.b. These aren't duff panels - I'm putting some identical ones onto my roof this summer.
