    Thanks...

    They have some interesting stuff there. Do you think they are worth the effort? Have you ever worked on any?
    Has anyone just installed a system that was seasonal... no glycol, blown out during the winter months? How about a direct loop system... no HX?

    Seasonal solar systems

    I have done all the above except have not had any systems "blow out" in the winter.

    I meant to not use during the winter months.

    got it

    I understand now. No need to blow out a seasonal system if you set it up right. Just open some valves and drain it down. My systems do solar DHW in spring, summer, fall and wood heat does DHW in winter. These are open loops with potable water. No glycol.
    Homeowner must sign off on being vigilent about WHEN to switch over the systems.

    Use it year 'round

    Solar for Dhw pre-heat works well in winter months. We have plenty systems in the upper Midwest and Nathan in Alaska who hangs out on the wall has some experience with cold climate conditions solar. Consider a plain water drain back system, freeze and overheat protection are the benefits.

    Thanks HR...

    as this point I would like to do a drainback set up but I can't swing a drainback tank. I am going to run the system at street pressure to a standard water htr and a bronze circ that I have. If the set up works well and business gets better I may do the drainback yr round.

    Got home today at.....

    5.30 pm. I had a 50 gallon storage tank filled w/ 135*f water. Wow. I wonder if I should have installed a bigger tank......

    How many square feet

    of aperture?

    The collector....

    is around 36 sq ft..... I am starting to wonder if I should have found a bigger tank. The plus side of having the collector at ground level is that  I can cover part of it up.
