Hey Mike, nice work, I dont know much about solar, what do you have for a heat source feeding the boiler buddy? And how does the solar tank work? does it switch from the solar side to the boiler side if the solar cant keep up with the load for the hw domestic? thanks

    solar thermal pics

    Hi All,
    Here is some pics of a system I finished two weeks ago. It is heating a basement radiator and DHW. 3 Gobi 4 x 10's with pv pump (laing D5). Controlled by a Resol "E" controller (Badass). The buffer tank is a Boiler Buddy.
    Thanks all

    What's the pipe for coming off your tank drain?

    CWS

    Rene,
    That is the cold water supply to the tank.

    Another interesting boiler buddy...

    It's not so much a case of "You got what you paid for", as it is a matter of "You DIDN'T get what you DIDN'T pay for, and you're NOT going to get what you thought you were in the way of comfort". Borrowed from Heatboy.

    The Boiler Buddy takes it's heat only from the top heat exchanger of the solar tank, not ever from the boiler. When it is hot enough (via a sensor in the thermal well ) in the buffer tank and when the zone calls for heat, the circulator on the right (in the pic) kicks in and dumps it's heat into the basement zone. The pump on the left circulates at different Delta T to keep the tank ready to go for when the zone calls for heat.
    Hope that helps
    Thanks,
    Michael

    Do you have a backup heat source on this system?
    I like the use of the boiler buddy! Who Makes the solar tank and how do you like them?

    nice!

    does the E control run the Laing via the PV panel? Is it C or F on the display, 120v? Did you do much programing to interface it?

    E controller

    Hey Hot Rod
    The laing pump is not yet being controlled by the "E". I wanted to see how the system did without a delta T. Just start PV. I will switch it soon, it is all set up for the switch over.
    It is in Celsius, I got a conversion chart off the internet, printed and lamenated for the customer to hang by the controller. It runs on 120v.
    I did do some of the programming. I used arrangement number 1 and set everything else via the function blocks. It has work out well so far.
    Hope things are going well on your end.
    Michael

    the alchemist again

    wopsie! I hit the wrong button!
    I just read your book!?!
    Anyway, I used an 80 gallon vaughn tank. I really like them. They are heavy SOB's
    ,but they work well.
    It is backed by an oil boiler.

    Wow. I didn't know Vaughn made a duel coil solar tank.
    Where is the boiler in relation to the Boiler Buddy?
    Nice job. Interesting too............

    well done

    I'd worry that the pv powered solar pump could, under some conditions, actually pull temperature from the tank. As it has no way of knowing what the tank temperature is when it starts the Laing spinning. Keep an eye on it.

    I agree

    that's why it will go on the Resol soon. During the summer months I want it to lose some heat, so I will put a switch in to go from winter (on delta t w/resol) and summer strictly PV.
