Hi do you know what the flow rates for D.W T. system please

I'd say you're right about things in common...You work on commercial washers, the company I work for operates on them (Ellis brand). However, I work on floor machines in another department of their business.

Thank you so very much!!!! You are awesome!

Hi Jim, I saw on a previous post that you know a lot about bell siphons. I am a newbie and have built my own, but am having difficulty with it. Now I can't get it to work and I'm not sure why. It has a 3/4 " standpipe, 2" bell siphon with 1/2" holes along the bottom all the way around... The bell is an inch taller than the stand pipe... It should work and it did a few times but then stopped, leaving 5 inches of water left in the grow bed. I'm using a 130 gph pump for a 55 gl tank and going up 4ft. Do you think its my pump? I would greatly appreciate any suggestions :) Thanks

Hey Jim,

If the air is warmer than the water, it's a tossup in my view.  The sweating might help a tiny bit, but very little of the heat absorbed will come from the plastic of your tanks. That's why I was thinking it's not worth the effort, though I'd love to hear the results of an experiment.  If you had metal tanks it might be different.

Thanks!

Hey Jim,

I wouldn't.  I don't think the sweating would be worth the convective heat gain.  

Hey Jim,

Thanks for asking.  Yeah I'm a dad now.  Same story as you - long induction and a c-section.  I just about lost it in the hospital.  Really good to be home.  Not much sleep yet but hopefully soon as she gets back up to birth weight.

Here's a link to some pictures.

Wow, Jim, looks like you have the perfect setup.  Great property for an awesome AP system!   I'm small scale, sub-division in town.  AP system, a couple raised beds and some young fruit trees.  Thanks for all the posting you do.  Helps us newbies learn.

Nice. What did you end up covering the hot house side with? The video shows it covered with plastic.

Hi Jim,

  Thanks for answering my question so promptly. Sorry I took so long to reply but I waited to respond because I wanted to see how the heat exchange my husband built for my yesterday was going to work. It works well. We  had to use cast iron 90's  because that is what he had on hand. I had a mishap shortly after we set the heat exchanger up- I slowed the flow too much and went inside and cooked dinner.  When I came back the pvc had started bending so I pulled it apart and drove quickly to town (13 miles in the freezing rain and sleet) picked up more pvc and when I returned my husband modified the exchanger( to try to prevent me from damaging anything else LOL ) by taking the s.s. across the top also and then connected to the pvc and increased the flow and the temp was 76-78.

  Today  I added some steel on top and in between of the s.s.   then I was reached temps of 87 on the out put and the tank was around 67 or 68 so I increased the flow and until it was a temp of 74 and now both the pond and the fish tank (about 700 gallons) is at 71. the air temp is around 60. So I am pleased with the heater.  Now we will see how well everything does if it gets down between 8 and 0 over the next few days.  Missouri is definitely experiencing winter weather, but thankfully we did not loose power.

Thanks for posting pictures of your heat exchanger. We had been talking about several options and after I heard that your s.s worked well we decided to make this heater.

Jim

hows it going? I'm getting closer the start up system, I was wondering if I could use stainless steel tubing to cool water in freezer, or do I have to use vinyl / pvc

Thanks Jim, your wealth of knowledge is much appreciated!  I should be receiving my IBC's (and hopefully a plastic 55gal drum, for a sump) this weekend.  I like to have a good game plan before just starting to cut & build..  so I'm sure I'll be in touch to verify some plumbing details, and other stuff, before I just try slapping everything together.  Thanks again for the warm welcome, I look forward to learning and cultivating.

Jim I've been telling Silvia about the break down in notifications.  Vlad also noticed it, and I think it is happening to a lot of people but few are saying anything.  Please tell Silvia about the notifications that you are missing.   I started a discussion and thought no one was interested until I checked it.  I had missed 5 replies!
