DIY Heat Pump 1

The beginnings of the DIY home brew heat pump. Hope to get the tubing all connected and pressure tested within a week. The home brew evaporator is installed so a good start. Making up an accumulator which could delay things a bit. The throttle for the testing will be a needle valve, ultimately will go to a TXV. Changed oil in the compressor. Ultimately will be a radiant floor heat system using a DC compressor powered by solar. More coming as the experiment continues....

Part 2 please. It is incredibly exciting build this one.

Neat little Freon to water plate heat exchanger. When I tried this 10 yrs ago the exchanger had a slight leak. Seller would never make it right; went to a tubing inside a tubing. Ed c

I'm eager to see your next instalment on this project.

[@ThisMaineThing]

I would be interested in a part 2 follow up

[@MichaelChristopherSmith]

This is your most viewed video. By far. The suspense is building for part 2!

[@tonygau65]

You videos are very good looking forward to more

[@pf_n1ps]

TNX. More vids coming in the fall.

[@johnadams5178]

Your doing exactly what I am thinking. Thanks for posting.

[@pf_n1ps]

OK great! I hope to get back on the project next month.

An update: I got this HP up and running about a year ago. It worked quite well The evaporator was/is a little too small and I need to update the tubing in it to 3/8". The system also needs a TXV and I plan to pick one up. However I will be going a new direction and changing to an air-air system for simplicity. I have other projects cooking these days (mostly radio related) and this one is on the back burner. But it may be next winter before I get back on this one.

[@yurii.lompart]

Still interested in this.

[@tonygau65]

You should do up an E-book an sell it on Amazon with parts list and then have some detail video that would be available for people who purchase the book

[@pf_n1ps]

Hope to have a new clip out by the end of the month with results from the heat pump project. Finally got back on it. I just released a clip on flare connections that really helped with the project.

Did it work ?

[@turtlewalzer]

I'm building 6x8 shelters for the homeless in Eugene, OR and hope to add solar heating to them, but need only about 1000 btu. Can this be scaled to work at that level? Would anyone be open to help figure this out?

[@azhar2626]

Wonderful project. What are the update right now please?

[@pf_n1ps]

TNX for watching. Yeah I have been busy on other projects so this one has fallen behind. But I got back on it this week. I'm cleaning up some of the leaks now,. a consequence of using a lot of (maybe too many) flairs. Hoping to charge it up and get it running in the next few days.

[@dominik8040]

Is a project still working? No update video found :(

[@pf_n1ps]

Yes I have not posted an updated video as yet. I did get the HP running with pretty good results using a small water tank, but I have to make a few changes to the system. Most notably I need to change out the 1/4" evap tubing (what I had on hand) to 3/8 to get better performance from the evap unit. Also I need to go to an AXV and shelve the needle valve. I wanted to post something this spring, but outside home projects have become the priority. TNX for the note!

@@pf_n1ps did you get it running? longing for the update :-D

[@sNEAKYnIGHTmUPPET]
