Solar water heater update…

Sometimes you gotta ask yourself: How much is too much?

Because I think live steam is too much.

And I don’t believe the plumbing, which is basically good-quality garden hose, is really going to keep putting up with it.

But in fairness it’s saving time and propane while it lasts.

    You might try partially shading your hot box. Staple a rag over it, maybe?

  2. Do you still have the glass cover on it? I always thought that was overkill for your environment.

    put a water heater pop off value at the highest point in the linet

    Or maybe open the faucet a bit – cool the whole system off by running more water through the “leaky” faucet. Maybe pipe it through a radiator in the shade, then to a storage tank, or just spill it on the ground if you have abundant supply. Seems to me that you have too much sun, so tweel’s variable shade makes sense to me – you just need an easy way to adjust for cool days and hot days and laundry days and shower days. I envision lots of pulleys and para-cord, but if it is at ground level, clothespins would suffice. Check your inventory for one of those reflective car window shades. Ooh – another thought: situate the shade for morning exposure and afternoon shade? Or even angle the reflective “shade” to get more sun into the box in times of weak sun.

    I can’t imagine that a tempering valve would last long with your water but they are a thing. A tempering valve adds enough cold water to the hot to maintain a steady temperature allowing higher hot water temperatures to be reduced to safer levels.

    None of the suggestions for adding cold water will likely be adequate, especially given your water supply is limited. If it’s glass covered, take it off. Shade it. Or, much more complex, scrounge up an 80-gallon tank and put it up high with the collection loop below it. Convection will circulate the water. Then you can have 80 gallons of steam!

    Holy hell, next thing we’ll be reading about how you’re installing a steam turbine power generating station for all the free steam you’re creating with your black hoses on the rooftop.

    Keep in mind, just FYI, the opposite can be true, also. On bright, hot days, your water system is going to trend towards hell temps, but on clear, cold nights, it will trend towards absolute zero.

    You could very easily end up with situations where it will try and freeze on you even when ambient temps aren’t quite under freezing.

To the stake with the heretic!
