AB Saltwater 85kBtu Full Titanium Heat Exchanger Same Side Ports 1" & 3/4" FPT for Salt Water Heating or Cooling, Aquaculture, Mariculture

I purchased two of these exchangers less than a year ago. Both units have significant rust developing despite them being made of supposed 316ss.

Exchanger was run as seperate zone off of oil boiler to heat 6000 gallon pool. raise temperature 8* in 1 hour. Oil boiler used for heating house with 2 heat zones and 1 for exchanger to heat pool. located in Pa.

I installed this to my outside wood boiler and it keeps the pool at 86° with 130° degree water from the boiler when the outside temperatures run from 70° to 85° during the summer. I haven't gone through a Fall or Spring yet but I'll just turn up the boiler if the temperature gets too low. No thermostat needed in this case but I might hook one up in the future anyways.

I bought this pool heat exchange to replace my old one and using for few months now, it’s working perfectly as it describes.Easy to install and I have to say the customer service was awesome, they got my question answer within 2 hours and that really save my day! Over all great product and Keep my pool warm and really to go even Highly Recommend!!

I'm using this heat exchanger as coolant cooler on my diesel irrigation pump, in addition to the radiator. It works perfect! before it was running about 230F now it runs about 160F. I use the irrigation water, to cool the coolant. A real Quality product!
