WE have a CB e-classic 2300, and are currently heating the house with exchangers in the furnaces and an indoor pool with the largest water to warter HX that CB sells. The boiler handles the house just fine but when the pool is calling for heat it puts a big draw on the OWB.
It is still enough to keep the house warm but it will draw the OWB down 40-50 and it has to run constantly to keep up. We are still on the first month of burning so there are a few kinks to work out but the burner is definately hungry when trying to heat 35,000 gallons of water.

I have a 24' round pool I would like to heat with my owb this spring. dirtyedge, how many degrees are you raising you pool temp?

It takes a couple days if I let it drop into the 60's but It can maintain 80's pretty well, and heat it up to high 80's or low 90's to swim in.
In our case its easier to keep it warm than letting it cool down and then have to reheat all that water.

I have to watch this thread .. been dreaming of summer and how I may heat my 24' above fround pool. this is how I did it last year before the OWB .. not real effective. I have plans in my head but have been confused on what HX to look for .. many say only stainless steel and the guys that sell copper ones say it's bunk and if the pool chemicals and PH are kept correct copper is no problem.. not sure whom to believe! Anyone hear of any good deals on an exchanger that will work please pass it on!
Using a hardy
I "y"ed off the pool pump and circulated it through the domestic hot water tubing on my hardy and returned it to infront of the jet using 3/4 garden hoses to and from the burner kids start swimming in early march and up to Halloween!!

sstan,
We purchased our water to water HX from Central Boiler, it is a 5x12 30 plate exchanger made for pools and hot tubs. They have to made specifically for pools to meet the rigors of the chemicals.
Ours was around $1500 which is far from cheap but better than having something go wrong and have the pool water start mixing with the boiler water.

Cupronickel would be the best for pool water but you should still keep your water well balanced.

No but I would rather pay $1500 once than have to worry about the cheaper $600-800 ebay exchangers or regular HW exchangers not holding up to the chlorine and having to replace in the future with the more expensive one.
Even with our HX we have it valved so we can stop all water flow through it when shocking the pool or if the Ph values are out of line.

Temp. effects the balance of the water more than the chlorine does so its important to use a saturation index. I put a link here to look at the formula. http://www.rhtubs.com/langlier.htm
A local company that makes snow melters has been quite busy so my contact will be looking through the scrap pile of stainless (can also roll what I need ), once I have enough material I'll build version of an OWB using the pump setup from a smaller above ground pool to circulate the water .
Any thoughts on the above ?

Just a thought, would it work to pour a cement slab and run in floor heat for an above ground pool? I know they usually set them on sand.

Yes
That is how my CB dealer did his AG pool, no cement though. Email Crystal Rock Farm and ask him.

Installed our above ground pool in September 2015 and have begun plumbing it. I plan on using a 210,000 btu tube and shell heat exchanger from freeheat4u and connect it up to my NCB 250. Someone mentioned making sure the system I install is "bonded" or grounded properly. Any of you hear of this when heating with the OWB?
I only use our OWB to warm up the pool in the spring. I just run a utility pump and pump the pool water through a coil of copper tubing that hangs in the boiler water. I takes about a week to get it from the 50s to the 80s. The pool is a 20x40 inground. After it gets warmed up the pool stays in the 80s with a solar cover.

My dad and I whipped up a quickee, just took a few hours, solar heater for our big family sized above ground pool back in the 60s, first solar project I ever worked on.. It was super easy, kmart had a big sale on garden house, he bought I forget, but two or three hundred feet of it, looped it back and forth on the south facing garage roof, then plumbed into the filter/circulator. We got an extra month in the spring and again in the fall swimming in warm water. Just turned the pump on and off night/day. Next solar project we did was easy too, we enclosed the backyard patio slab with some greenhouse panels walls and roof, and there was an existing normal big sliding glass patio door there. A thermometer by the door, when it hit 70 in there in the winter, the door was opened. It put a lot of heat into the house during the day in the winter.
