## Description

AB Plate Heat Exchanger, 3 x 8 Inch, 20 Plates, 316L SS, Copper Brazed | UL Certified; sealed, compact design for efficient heat transfer in floor heating, water heating and hydronic systems. - desertcart.com

Review: 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.
Review: plenty of heat coming from a toyo 180 boiler 3000 sq ft in floor heat and domestic hot water - Plenty of hot water for 4 people plus
