I tried the t in my filter line and found that it took the path of least resistance and did not pump more then 2 feet high. so I found someone with a spare above ground filter/pump used some jb weld to reduce down to 1/2 inch on the output ran 2 black 50 foot garden hoses to the peak of my roof (22 feet) coiled out 100 feet of 1/2 inch pvc I did not want to t off the filter so i just hung the intake hose over the side next to the skimmer sometimes i have to prime it to start it. it raised my 15x4 foot pool by about 12 degrees now I can just keep adding 100 foot lenghts across my roof peak to increase the temp 18 dollers per 100 feet works great recomend to everyone jim

fire pit heat

I really don't like the idea of having to climb up on the roof to to install the collector. Not to mention the installation and plumbing problems.

My pool is an 18ft above ground "portable" pool, the type that's vinyl sided with a metal framework suspending it. I already use a solar blanket, and have one of the harbor freight pumps, so any additional heat would be a bonus. If black pipe coiled on the ground can produce acceptable heat, I'm all for trying.

As an aside, I've also build something similar to the "redneck pool heater". In my case I took a old car radiator (aluminum) and placed it over my fire pit. Nearly 100% of the heat produced by the fire was transferred to the core area, with the top side of the core being cool to the touch. The hardest part was keeping the fire burning all day! I think if I was burning wood pellets instead of scrap lumber I might have had better luck.

When I was young, we had 200 feet of black pipe coiled on a 8'x8' platform.
It raised a 25ft standup pool by 12-18 deg F. The temp went from 65-68 up to 75-84

What ever happen to the solar fence that was out 11 years ago, where the pool water was heated inside the PVC fence?

I was wanting to try a redneck heater, could you put in a bypass and control with valves as long as you could maintain your operating pressure. I have a 23'x32'x48" inground and was wanting to try 300 hundred feet of 5/8 black hose, cut in a tee after filter and cut it back into return line so there would not see a garden hose going into pool plus little kids around dont want to get burnt. Also hang on south side of fence for max solar power

Will a Syphon work to keep 2" abs water heater flowing

Postby Thomas74 » Sat 17 May, 2008 11:37

I'm interested in hooking up 400' of 2" Abs pipe and have it flow naturally with a syphon instead of the costly water pump. Any feed back on this approach???

I just built a coil solar heater, but haven't gotten good results with it yet. I ran 2" PVC lines up to the roof (with a check valve IMMEDIATELY after the filter to prevent backflow when the pump shuts off). I have a ball valve on the upflow, and a bypass ball valve so I can divert some, all, or none of the water to the roof. I made 4 coils out of 3/4" poly tubing from lowes (around $20 for 100' coil) The coils are connected to two headers. The headers are 2" PVC with a Tee and a threaded 3/4 reducer, Using the pex 3/4 male threaded connector to connect to the headers. The coils are held together with pvc electrical conduit (2 -10' sections cut in half) and they form an X on both sides of the coil, and are bolted with five bolts. One in the center, and 1 on all the ends. I thought 4 would equal the same flow as my 1.5" pool line, but the pressure spiked for 10 psi to 20 psi so I had to open the diverter valve to allow some of the water to bypass the roof. I don't want to burn out my pump. I bought enough PVC to make 2 more coils, but I'm gonna use 1/2 inch this time. I might be able to make 200' coil in the same space as a 100' 3/4. If that's the case, I can collect more heat, and build one more, as that is all my roof will hold. If it works better, I can rebuild the existing 100 ft 3/4" ones with 200' 1/2inch. I will only be out $80 for the 3/4 coils. I'm sure I could use them for drip irrigation in the garden i want to build in a few years anyway.

You don't mention an air bleeder. Up top you need to have a valve to bleed the air out of the system. Your pressure will spike quite a bit until the water starts flowing back down the other side.

I did not put an air bleed valve at the top, and I've been thinking about that. What would you suggest I use? I did not see anything in the pvc aisle I that would work. I did install a check valve (much smaller than 2", on the top end of the manifold I reduced it to 1/2") to let air back in when I cut off the flow (usually around 7 at night when the shadow of the higher roof starts to cross over). I did think about getting the air out. I just figured it would push out when the pump kicked back on, but a bleeder would definitely help out the pump.

Find a shop that has parts for radiator / hydronic heating systems. They will have automatic air bleeders you can use.
