I used to have the opposite issue here in Arizona with the water getting to warm but figured it out over the years. I can imagine that keeping the water from freezing in your much larger system could be a challenge for sure. Good stuff as usual. Thanks for sharing and as always keep building👍
I admire your thorough and thoughtful approach to each component of your system. Thankfully, my aquaponics system is in Thailand where I don't have to worry about this aspect
$10K for a wood heater seems disingenuous or a way to get out of having to treat it as a real option, a wood stove with a heat exchanger on top of some type that would keep the water from getting too hot, but also warm the structure. Building something with a normal heating stove would be much lower cost. If you are to ever get the system to be commercial you need to have the system producing in the winter with both warm water and warm greenhouse. But as it looks the system over 3 years, it's still just an expensive hobby and not expanding beyond that. The cheap Chinieeze heater is a low enough cost unit and fast to put in, just seems like a patch rather than a solution.
You should be good to bypass the pressure switch because you still have the overheat sensor. It the flow stops it overheats and shuts down. Pressure to an alarm would be better.
Rob, Love the cost breakdown, thanks for those calculations. I'm up in NH and have similar electric rates. That said, I recently added a DC powered heating element with a solar panel to my system (total cost about $300). I know at the moment it only gives me a couple of hours of heat per day, and I haven't done the math, but in my mind every BTU gained from the sun is a good thing.
I've been debating doing something similar but just run water through a parabolic solar troth. With PV panels there is a lot of loss to convert from solar to electricity. If you can heat the water directly, I think it might be more efficient. Of course there is plumbing involved...and making sure the system is drained at night (or filled with antifreeze and run a heat exchanger)
It takes a tremendous amount of energy to heat one gallon of water one degree. Can't imagine how many btu is required to heat this system properly. I would doubt that little heater is very effective, except in very marginal temperature needs.
Just wondering, why not use a duel input geothermal heat pump? It cost almost nothing to run. If you do it yourself, 1500 cost max. I'm looking into getting a greenhouse and will need cooling and heating and weighing the pros and cons. I want to add wood or solar or both energy storage to mine, but I'm making it myself. Done a ton of research into this. I can weld good enough to make something descent. Still hashing out the design for the storage.
...Reason I'm adding wood stove into the storage mix is for those few snowy seasons we get with little light so solar may not work well allowing me to grow anything without exception.
I had made a pretty good wood boiler out of an old wood stove which worked well in the other greenhouse. I just don't have the time to cut firewood so it's easier for me to just heat with less eco-friendly methods. A heat pump is good but it still takes power to run and a source of "heat". for this area it's underground and everything is bedrock. cost to install a few wells can easily exceed $20K. Heating a greenhouse is very different than heating a house. Even an "efficient" greenhouse is very poor compare to a house. It takes a lot of energy to run a greenhouse when it's cold....or like what I do, just keep it heated enough to prevent the water from freezing. It's cheaper (for me) to not grow over the winter than to pay for heat and lighting.
@@Bigelowbrook TY! You said, "It's cheaper to not heat...". I can see that. Do you sell any crops to offset the cost? I'm about to build one and will probably make a Chinese one with some homemade improvements. I also love fish (eating) so it's hard to not also have some 🐠. Have not researched this at all though. Lastly, I like to help when possible and as a thank you:. If you want to increase production with CO2, I think I've found a cheap easy solution after many hours of research?
I think my 15in stanley hand saw is easier and faster... (they sell a 12in PVC saw I've wondered about, but a moderately coarse tooth wood cutting saw works great). I agree with your cost analysis. Lifecycle cost is something too many people ignore.
Not sure where to add this comment. I want to build a greenhouse. Saw your presentation from 6 years ago on them. Which type would you recommend now 6 years later for a small commercial operation?
@@Bigelowbrook yes I've thought the same. Can't think of anything 🤔 better. I'm in north Arkansas. High humidity midway between real cold and hot, more on the warm side but occasional snow.
@@l0I0I0I0 You're in a fairly warm area. I would probably just install a heater to deal with the occasional cold night and grow cold crops over the winter
why not going into solar it's expansive but in the long run, it will pay itself before the replacement/ maintenance kick in, European panels are warranted for more than 15yrs, after 7yrs it will pay its self, the cost is directly proportional to the amount of KWH you'll consume
Is it 240v? Also shouldn’t it be on a ground fault breaker? It has 3 wires yellow with green stripe obviously ground. I don’t have a schematic. Then there’s a brown wire and blue wire. 120v to brown and 120v to blue 240?
Please help me: I put mi vevor 3KW after the filter of my bath/spa ( 3000liters) , the pumping is the same for all spa. and have 1/3HP jacuzzi 1/3CV, I saw that the water trough out with good pressure , but the ligth not tiurns on? maybe my pumping is too much strong ??
@@Bigelowbrookhow do you bypass the pressure switch. As my pump isn’t quite enough to trigger the heater unit , the orange light is not on ??? Can the pressure switch be bypassed ?

Great cost breakdown. Thanks!
Check out pellet boilers, furnaces, and stove. Burns so clean you may want to vent it into your greenhouse.
Little bit of engineering. Little bit of science. Little bit of math.
APPROVED.

@@Bigelowbrook Hmmm...I will have to look into making a parabolic solar troth for my next heating project.
Nicely done!
Solar water heaters perhaps?
I was curious after 3 months how this heater performed in your opinion
I was looking forward to the follow up to part 12 & 13 from a year ago on the Radial Flow Settler.
It takes a tremendous amount of energy to heat one gallon of water one degree. Can't imagine how many btu is required to heat this system properly. I would doubt that little heater is very effective, except in very marginal temperature needs.
Excellent breakdown,thankyou
Why don't your videos show up in my sub feed!!!?
Nice calculations
Wont putting it in backwards possibly disable the pressure switch?
Edit: LOL of course you use the same adjustable pressure pumps as me.

What is the lowest temp this system produces? Looking into heating koi pond
Perfect
6:31 seems like you're going to be heating the ground.
That is exactly what he is doing...

I also use my hand saw for the majority of my cutting, but instead of grinding it into the dirt, it's a lot easier to use the cable saw.

what was the maximum gain in heating, I only saw 2 grades gain
Hi,
I have question is it really need to connect to board panel?
Your channel is really starting to heat up.
Maybe the "Whirl" is for whirlpools
Could you tell me what does the prompt AC2 mean?
This channel had so much potential so sad you let it die like this
And who says its dead?
It was 37 C here 2 days ago

I don't know enough of the details for this unit. You probably should contact the manufacturer. Sorry!
Can you heat a pool with that thing?
That is what it's designed to do...but this model is for a small one.
It is a hot tub heater, just with built in controls.
Which pump are you using?
