AB Plate Heat Exchanger, 3"x 8" 50 Plates Water To Water Heat Exchanger, Copper/SS316L Stainless Steel Brazed Plate Heat Exchanger For Floor Heating, Water Heating, Snow Melting

The 30 plates exchanger does a really good job at heating our domestic hot water tank for our family of 4. Easy to install with PTFE teflon. Highly recommanded. Their customer service is also very good.

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.

By putting in a larger unit I increased my hot water considerably

Great product! Looked at many but this was a agreed by. Superior heat transfer considering the size of the unit. Used to heat indoor pool from outdoor wood boiler, but would great as freshwater heat transfer.

Used on an in floor radiant heating system in my garage. Loop from boiler heats up the heat exchanger which heats the water/glycol mix for the in floor loops. I was skeptical such a small heat exchanger could put out the rated btu but it performs better than expected. Good build quality. Gave it four stars due to the poor instructions provided. I don’t read Chinese so I relied on the pictures to identify piping connections.
