UPDATE:
The inlaws came to stay the past few days. Here are the numbers. 3.5 days 5 extra people + me and wife = 7 people 6 loads of laundry with wash on the warm water setting 4 dish washer loads and about 9-11 showers a day plus what ever hot water was used for normal sink dishes/hand washing. Results: 17kwh .11 cents per kwh total of $1.87 divided by 3.5 days = .54 cents a day pretending that this was for a normal family of 7 people full time this unit should use .54 cents x 31 days = $16.74 or 365 days x .54 cents = $197.10 for hot water all year for a large family of 7 people. The bore hole temp never dropped below 36F even though the compressor ran for 13-14 hours a day. |

What? It still works? IMPOSSIBLE! That should have exploded by now.... Grumble humbug.
Just kidding. Good to hear it held up under a heavy load, well on its way to paying for itself. Once you break even, the rig will just keep on saving more and more money as energy prices go up and up. Last edited by jeff5may; 08-17-15 at 10:46 AM.. |

Thanks for Giving Back!!
MEMPHIS91,
Sounds like your system has passed the acid test! * * * In the beginning of this thread, you said that you wanted to 'give back'. These were your words... I want to say that your project has not only been an adventure, and a success, but you really have given back just as you said you wanted to do. You have left a written and photographed record of you plan, your follow-through, your mistakes, and your ultimate success, which will stand as an inspiration and road-map for very many readers to come. I hope that others who read your thread recognize the very wide-ranging value of your example, not only your success, but the fact that you elected to Give Back... I hope others follow your good example. Thank you, and randen and any other EcoRenovators who have taken the effort to shared the process of their work, as well as their success. Sincerely, -AC_Hacker

Thanks again!
Just wanted to say thanks for your really elegant solution for putting the tubing coil into the hot water tank. Your plumbing days certainly helped you there and you helped so many of the rest of us!
And the long tale of dialing in your charge and cap tube (and being steered away from the txv) really inspired me to get back at mine. Thanks Guy! |

Ron, thank you, I hope your system fires very well.
I forgot to post the 2 month data, so far from start to 2 months it used 144 kwh. Next step/ idea, I really love this DX system, but going off grid makes for some changes. I have a few options that I would like some opinions on. First would be to solar power the system, I could turn down the thermostat lower and decrease the max needed amps. Then 500 watts of solar power. I could use no battery and only let it run during the day, with 90 gallons of storage I could go a day or 2 without any sun and still have some hot water. And have a generator just in case I got no sun for longer than that. Or a could add some batteries and extend the run time. Second would be to go solar water setup and use the heat exchanger in a closed loop system. Or a could use a combo of the second option and a wood boiler loop in the chimney of one of my 2 wood stoves. Or a could do a huge tangled mess of things and use all three options with the DX in the bottom of the tank and put in another hear exchanger in the top for solar and wood boiler loop. Ideas? |
