Well built, using as boiler
It sits on top of a new wood burning stove that reaches 500F on the surface, a timer is connected to a circular pump for floor heating pipe buried in concrete. Pump on for 2 minutes, off for 20 minutes. Thermal transfer fluid to the slab has a boiling point of 650 degrees F. I let the fluid get very hot, then the pump moves it for 2 minutes, enough time to push a gallon of very hot water through pex pipe under the building far end of concrete slab. Then the pump stops and the heating process repeats for 20 minutes. Rapid slab warm up using this timed start / stop procedure. Using this unit as a boiler essentially. Heats slab much faster than thermal transfer fluid always circulating. Excellent product, will but the 50 plate unit next and sell this 20 plate unit to a friend.

Hoping it is a problem solver
I purchased this to isolate a condensing boiler that has (according to the manufacturer) oxygen issues that are causing premature failure. Hopefully it will work. The mix of.hot water and hydroponic system water is segregated and all PAX barrier or SS is on the boiler side precluding oxygen from causing corrosion.

Spend money on an exchanger that works.
Did not work as described, defective unit which was past the warranty, which was my fault not getting it installed In time due to construction delays. Support was was good at helping me trouble shoot the exchanger to no avail. I due run 3 other plate exchangers on my property with no issues but a different brand. My advice spend the money on a reliable exchanger and a company that backs their products. I would not recommend this product for purchase.
