AB Plate Heat Exchanger, 3"x8" 20 Plates Water To Water Heat Exchanger, Copper/SS316L Stainless Steel Brazed Plate Heat Exchanger For Floor Heating, Water Heating, Snow Melting

I put this heat exchanger on my car to use as an engine oil cooler and it is working great so far. I am running the oil through one side of this heat exchanger and coolant through the other side. So far so good, the oil temp is staying within a couple of degrees of coolant temp and there are no leaks, so I am very pleased. The other thing I like about this heat exchanger is that it came with the ports covered to keep debris out during shipping. I flushed the heat exchanger out with acetone before I installed it to ensure that there was no debris or metal particles in it, and it was perfectly clean.

aun no lo instale, pero se ve muy bien.

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.

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.

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.

I wasn't sure what size to get so I just got a big one. I installed this on my domestic water heater and then shut off the power to it. After a couple hours my water was hotter than normal and I think I might have unlimited hot water, after four showers my wife took a bath and the water was still hotter than normal!

Ordered a few of these in the past. Price is great. I mainly use them if I need a hydronic zone off a gas steam boiler, only a few companies have tankless coils on gas boilers, so this is a good option. If you are using this on a steam boiler make sure its maintained and flushed.

This product is well made. It was easy to install and works just as I expected.

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

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.

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

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.
