I believe you would have better heat transfer by running it through at a higher flowrate. The difference (Delta T) is greater at the higher flowrate allowing more heat to be transferred. Yea, not as many dgrees are picked up, but you are also moving a whole lot more water.

Can you share your plans on how you built the wood fired pool heater. I am trying solar but it does not work well and gas costs make me cringe.

I just got my heater up and runnning. Here's how I built it:

It's a wood fired, u-tube hot water boiler. Don't let the word "boiler" scare you, it doesn't boil the water, it just raises it about 3 to 4 degrees C on each pass through.

A 45 gallon drum lays on it's side. I made some quick feet out of 1/4 x 1 flat bar stock, self tapping screws used to attach the feet to the drum. This thing is top heavy, so you don't want it rolling over.

The bundle is made of 1/2" thin wall copper pipe. An inlet header of 1 1/2" PVC pipe and an outlet header of the same.

I made each header out of three short straight pieces, and two 45's, so the header sort of follows the round shape of the drum. Put a cap on one end of each header, and nipple to attach the hose on the other end. Drill each header to receive the pipe, mine has 20 holes in each header. There is a total of 40 tubes in the bundle, each the length of the drum, (appx. 3'), so there is 120' of copper pipe exposed to the fire. Copper 90's are used to make the u-tubes. Water flows from the inlet header, through the 20 u-tubes and out the back into the outlet header, and dumps back into the pool. Soldering is required to make the tubes. I glued the tubes into the holes that were drilled into the pvc headers. A white two part epoxy called Wet Bond is what I used, but it softened up and blew a few holes after the boiler was fireing hard. I ended up useing Copper Bond copper pipe epoxy to cover the Wet Bond, and it works quite well. It is half the price of the Wet Bond. Four units of Wet Bond were used, at $20.00 Canadian each, compared to Copper epoxy at half the price. It adheres to the pvc very well, so I would recommend to use only Copper epoxy.

Water is pumped from the pool with a submersible sump pump, through some cheap, flexible black sump pump hose, into the bundle, and dumps back into the pool. The pump inlet is covered with a lady's nylon stocking and a nylon door screen to filter the water.

The bundle is a semi circle shape and fits up in the upper half of the drum. The fire is made in the bottom half of the drum, and heats up the tubes. Cut a tabbed hole for a 6" wood stove chimney pipe. Cut a hole for a door, and bend all four edges out a half a inch. Make a door out of the heavy bottom of a second drum. Build it about 1 inch larger than the door opening, so you can affix some gasket rope around the edge for a door seal. Cheap hinges, and a door clasp are screwed on. Be sure to put the door opposite the pvc headers, or you will have trouble fitting a large enough door opening below the bottom header. Also, put the door opposite the bung holes, and keep the large bung hole on the bottom, so it can be used for a air inlet for good draft.

Use wood stove cement to seal the slots or holes drilled into the drum ends where the tubes go through. You don't want heat getting outside to the pvc headers. They could be insulated with a combustible proof insulation, but then you want to be able to access the glue connections to touch up any leaks.

After you have circulated water through the bundle, checked for and repair any leaks.

Let the stove cement dry thoroughly.

Put a layer of sand on the bottom of the drum to insulate the drum, and provide some thermal mass.

Be sure to have water circulating through the bundle before the fire is built. Never shut off the pump if there is any heat in the drum, or the tubes will be overheated, and worse yet, the glue and/or pvc headers could be damaged.

I am going to put an air bleed fitting on the outlet header of my heater. I will drill a 1/4" hole in the top center of it, glue a nipple in and attach a rubber tube to it with a clamp. The tube will be tie wrapped along the discharge hose to vent off any air in the bundle into the pool.

I warmed the pool 10 C degrees in a day and half of casual attention. Its cool, rainy September here now, so my goal is to get the pool up to 30 C, have a good swim with the family, brag about my heater, and take it all down for the winter.

I have some pics of the project that I could e-mail if anyone is interested.

Heat up your pool everyone!

I have learned that you want to maximize the flow rate through the heater. It puts minimum load on the pump, and if you only raise the temp of the water a few degrees from the inlet to the outlet, thats good. This warms the pool faster and more efficiently than by cutting your flow, loading the pump, and having hotter, but less flow.

Be sure to filter the water that goes through the heater.

Heat your pool!

The web-address for warmwatersource does not work. Is there another address ? or a brand name so I can do a further search.

I have been experimenting with building one myself. So-far I have had fair results. I am getting about a 25-30 degree at about 10 GPM, but with a 24' X 15' pool the temp didn't rise as fast as I would like. I have a few modifications to try (bigger chimney, an adjustable vent door to adjust draft (better combustion), brick lining to retain heat, and more copper in the firebox). Anyother ideas would be appreciated. I have all winter for modifications.

peter1, check this link for the wood burning heater you can buy;

no price listed on the web, I emailed them to find out.

I can't quite picture what the homemade one looks like either. I can picture something in my head that might work though.

Now that it is winter, The 'build' has slowed, and I just got a digital camera, so if I can find out how to get a picture to you I will.

It is not pretty, a 55gal. drum on its side, a 5in dia. chimney pipe out the end, and a metal door on the front.

Hopefully this weekend I'll take the pictures.

Chlorine attacks copper big time! It WILL turn your pool green, and many times do it overnight. The amount of copper in the water will make it so toxic that it's considered hazmat and you'll get in deep crap just trying to get rid of it. Do a search on pool heaters to see what is used for the heat exchanger - STAINLESS STEEL! And only stainless... That's why they cost a good amount to buy them. This guy used over 120ft of copper pipe in the "system". He's nuts !!! Ask him to get his water analyzed before you make the same mistake. Don't believe me? Do a google search on pool heaters/copper. Then recall your chemistry and read how much trouble it causes. Have fun swimming in that toxic soup :)

Hey guys,

I have a three year old wood burning pool heater that I purchased from warmwatersolutions. Parts of it need to be sanded and repainted. We're moving and can't take it with us and it's not the kind of thing the next owner will want or understand...

Email for info!

Its been a couple years since I've used the heater. Being a prototype, it had some maintenance issues, and I'd build it differently the next time.

Instead of using PVC inlet and outlet headers I'd use 1 1/2" copper pipe and 45s instead. That way copper sleeve nipples could be drilled and soldered into the headers. No glue would be required. The Copper Bond was pretty good, but I spent too much time fixing up leaks.

The idea works great. Three to four degrees increase from the inlet to the outlet is pretty good. The pool was up to 30 degrees C in a couple days.

As for stainless steel, that would be a great idea. I'm not a welder, but I like to build stuff. The whole idea here is I am trying to save a couple thousand dollars, and still get a warm pool. This barrel/copper pipe prototype cost maybe $200.00. The water stayed crystal clear, and no, it didnt' turn green.

I'm opening the pool again this summer, (my kids are bugging me), and I'll hook up the old barrel heater and see if it has any leaks. If there is too many, I'm going to scrap it and maybe try and fabricate some copper headers.

I'll keep you all posted.

My pool heater runs on nuaartl gas. The company installed it when they built the pool. The gas company had to bring out a larger meter to handle the increased demand, but there was no charge for the installation and checking the other gas appliances in the house after the change-out. I live in the Dallas area and don't heat the pool in the winter. I heat the spa. Unless we're having a terribly cold winter and I use the spa a lot I don't notice much of a difference in my gas bill. I think if you've already got nuaartl gas service to your house you need to stick with nuaartl gas for the pool heater.

Sizing a gas pool heater involves many factors. Basically, a heater is sized according to the surface area of the pool and the difference between the pool and the average air temperatures. Other factors also affect the heating load for outdoor pools, such as wind exposure, humidity levels, and cool night temperatures. Therefore, pools located in areas with higher average wind speeds at the pool surface, lower humidity, and cool nights will require a larger heater.

Have you tried the TimberLine wood fired water stove. They are meant to heat hot tubs and pools. They come in three different sizes and have added safety features such as built in temp gage and a pressure release valve. Their large wood fire pool heater is ideal for anyone that has wood at their disposal.

New to the forum. I'am building a wood fired pool heater using a old fisher wood stove. will be using stainless steel pipe mounted to the inside top of the stove. Here is my question?. many people doing this use 50-100 ft or more of copper tube i guess the stuff you buy from home depoit or such. people say some problems are, making sure the water never gets cut off or it could melt the tube or the soilder. plus others have said it put strain on your pump going down to 1/2" in size. I was going to use 1 1/2 stainless sch 40 to do two things. #1 it wont hurt the flow rate. and #2 someone had mentioned its better to have more flow not so hot but heating a larger quanity. So which is more correct? lots (like 100') of 1/2" copper tube or lets say 24' of 1 1/2 stainless pipe. thanks for any advice my name is dave

hi all hope someone may be able to help i have a WSP Siverdome wood burning stove that doesnt appear to be heating the water i have had a fire burning for 5 hours but there is no change in the temperature of the water I am at a loss to why
I have attached a pic of the set up at the inlet and outlet on the burner..there are a couple of what may be drain plugs above the inlet and outlet im wondering if these need to be opened or closed to allow the water to circulate within the woddburner
