AB Plate Heat Exchanger, 3"x8" 10 Plates Water To Water Heat Exchanger, Copper/SS316L Stainless Steel Brazed Plate Heat Exchanger For Floor Heating, Water Heating, Snow Melting

Never got to use it yet but looks like it will do the job

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.

Used for air flow instead of water, a mini air heat exchanger with a fan on the fresh air intake. Works well for this application.

Purchased this heat exchanger to heat the water going into the hot water heater. The exchanger works very well as our wood burner is normally set at 180 degrees. The 26 plate exchanger is a bit much though for our family of 3. The water from the water heater get extremely hot. When the boiler is heating the water for the water heater, the furnace does not get as hot as when the hot water from the boiler is going straight to the furnace. The heat exchanger is easy to install. Our hot water heater has not used any electricity since the heat exchanger has been installed. Well worth the money.
