    solar and heat pumps



    At various times people have chimed in on those micro channel solar panels with refrigerant in them. I am wondering if anyone who has installed them has any evidence as to their effectiveness. Any real experience at all?

    I'm having discussions with builders here who may be getting sold a pile of dung.

    Not personally but I have trained people who install them
    and one manufacturer recently did some training. We had
    a good long talk about there use and design and they did
    sound good.

    Not really to my liking but they do seem to be very cost effective.

    Rob, can you get any proper performance numbers or at least some 1st hand install info? (and maybe some links to product) All I get is distributors bla bla bla

    Cheers,

    Mike

    I have a document he gave me but it is the usual glossy advertising
    document and It is in my office, I won't be there for a few weeks
    but you are more than welcome to it (or a scan of it) if it helps.

    As for actual numbers and details, sorry I have nothing, The guy suggested
    I act as a sort of consultant to them because he was very interested in
    some of the views I had re gaining more efficiency but I never pursued it
    because I'm so busy with day to day work.

    I remember them using small condensing units and getting returns in the
    region of about 4 COP with temps over 50 degC. I seem to remember they
    do cylinders up to 500lt (I'm sure that's correct).

    Sorry I can't be any more specific, it was in November last year and I've
    slept since then

    I think I could find his details if you want them and you could talk to him?

    Regards

    Rob
