Not this pigeon Sunking! But man they show some beautiful architecture out there in the world (a bit jealous). Paul it sounds like if you need 4 acres you were definitely doing some Global Warming ... now I know who did it
. I was trying to put three sets of coils in an area 50'x150' but honesty the roots are going to be a bear plus the blue clay. Looking for a DIY well driller. I do like to know you seem satisfied with the whole install in the end. Thats important but my problem will be the county code guys. I am trying to make my frog over the garage into a future apartment when I am too old to work and need some extra income and not a place to reload bullets and take tasteful nudie photos of women ... lol... well that hasn't happen since the new wife. Ok I don't know how this forum feels about ranting on and on so I am going to shut up. You can find me somewhere else asking noob questions on the forum.

Eggs-actly just answering a question. I have a lot of useless PV stuff stuck in the peanut butter. Started storing solar crap since 1983 and cant throw anything away I even have literature on whole house AC that runs on Briggs and Straton engine talk about pigeonsPaul the issue is negative EROI. It takes more power to run the pump, than the extra power gained by using a pump. Yes you can buy pumps and panels made to do that. But the economics and EROI do not work. Like smoking, makes you feel good, but will kill you sooner than later.Leave a comment:

Big mistake Paul ... I went down the rabbit hole ... Inhabitat.com ... didn't find the solar panel yet but its definitely side tracking to go there ... wowLeave a comment:

Paul thanks for that pump info ... I am looking to install some pulled Geo Thermal heat pumps in a garage and I may do a 6' under ground closed coiled loop setup if I have enough yard to make three sets of them. Sure beats paying for three 250' wells at $1,400.00 each.

I do appreciate the straight talk ... definitely needed. I already have some Taco pumps made for hot water but as you guys mentioned its probably more cost and energy then the payout. Kinda makes me wonder if those little hot water heater to the kitchen faucet recirculation pumps could handle something like this on a lower power consumption. Where I live we see snow for about 1 day a year. Still using copper tubing would get very expensive these days. Maybe I will resort to ordering me a container of these solar coffee / tea brewers and hook them up in series ...
shoot it even purifies creek water!

Nice.
Grundfos Alpha circ pump,very low H.P. very small very efficient This 1 Pump Moves water thru 750 Ft of pipe.
But were getting in the weeds. Inquiring minds wanted to know If?

What type of pump hp do you need to move the water through tubes behind the panel will depend on the number of panels and the height of the system. Also how do you store the heated water?
Again, the thought makes sense to use the waste heat but is it practical?Leave a comment:

Old and tired idea. Economics do not work.Leave a comment:

From what has been discussed on the subject in the past is that once you figure in the cost of equipment, installation and "energy" the net savings is very low.Leave a comment:
