Hi, I am working on my water to water system. I need 3 ton unit, but they start from 2 ton units and they are not too expensive. I will post link later when system lets me do this

I am currently building drilling rig. I decided to build pretty serious machine.

Vlad · 08-25-10, 12:56 AM

I am using 5 hp electric motor hydraulic pump high torque hydraulic motor to turn the pipe 2” pipe. I am buying real bits for drilling wells on ebay. I built water pump for circulating mud 5hp electric motor as well. I bought serious water swivel on ebay. I just do not want to sit and scratch my had in the middle of the drilling. I want to drill 6 holes each 100-120’ deep and I want to make it for sure.

I decided to use electric motors vs. gas because I do not want to make to much noise and make my neighbors feel angry. And electric motors is easy to control no clutch needed etc.

I saw how AC_Hucker tried to fuse hdpe pipes . You could use other method to connect them you can buy couplings and use socket fusion tool which is 300 new on ebay or you could bid used one for less money. I would not jeopardize the whole project because of faulty weld which is now berried deep in the ground.

I know my drilling rig will cost me about 3000, but the same machine run over 10000. I will document everything make nice video. And sell it later for the same 3000. Plus it is a lot of fun to build things for me.

Finally I can post links after 5 posts. Here is a link to the company that sell water to water heat pumps. The smallest is 2 ton. The price is great.

I'm very interested in hearing about this.

Vlad,

You're right, $2595 for a 2 Ton GSHP is a good price.

Glad you're choosing water-in-water-out, smart choice. As know (for the benefit of new readers), the Carnot efficiency theorem tells us that the greater 'delta T' we make our heat pump create, the lower the efficiency we will get. With radiant floor (which I am working toward) a working fluid (water) temperature of 90-95 degrees is usual, with 80 degrees being possible with a very well insulated house and a highly-optimized floor design. Compare that to the need to reach temps of about 120F+ with the Air Handler approach.

I'm very interested to see what kind of drilling rig you create! I understand what you mean when you say 'I decided to build pretty serious machine'. I really underestimated what I would need to do my job.

Good luck to you on this project. And don't forget safety. I had a couple of close calls myself. If it is at all possible, it would be very smart to have someone else there working with you... I was working alone when I got into trouble. Things could have easily gotten very bad, but fortunately, nothing too serious as it turned out... I still have my hair, my eyes and all of my fingers.

Best of Luck!

great job ac!! i have enjoyed this thread alot. since i see you are a great crafter, sounds like you need something for the pipe to lay on, say v shaped with a clamp or to to hold it. now if you could have the heat plate in the center that swings out of the way after heating of course then you could join your pipe and use the clamps to hold them in place so they didnt move. a rubber strap oil filter wrench could be modified i think for this. also maybe have something solid on one end of pipe and on the other end that would put pressure on the pipe to make a good bond between the two. well just an idea, hope it helps in your next creation. lol great job and look forward to seeing more from you.
