Review: Haven't installed it on the wood boiler yet, but built the assembly waiting for a warm day to hook it up. Seems to be constructed well and and fairly heavy. This is a identical setup to what is currently being ran to heat a 6000 gallon underground storage tank. The other wood boiler is smaller and we used a 40 plate as an proof of concept. No complaints as far as efficiency! If I remember correctly, 170⁰-180⁰ boiler water goes into the exchanger comes out around 145⁰'ish. The other side comes in at 56⁰ and goes out around 78⁰ish. Roughly about a 20⁰ delta throughout the entire heating process. It will bring the storage tank up to about 120⁰.
Review: Just finished my install and have had it running twice. So far I have been very satisfied. My closed loop is running at 150 degree F and my open loop target temp is 120 degrees F. I started with 2,000 gallons of 48 degree water during my first test and raised the temp to 100 degrees F in about 2 hours. I still need to insulate the HX and all of my pipes.

## Features

- EXCEPTIONAL PERFORMANCE -- ALECOIL brazed plate heat exchanger is made of high quality 316L stainless steel and have been brazed together with copper in an oxygen-free furnace. This provides unparalleled strength to support the widest range of high-temperature and high-pressure applications.
- SPECIAL PROCESS -- Uses an asymmetric fish bone plate design that creates strong turbulences and moves the two media in opposite directions for superior heat transfer rates and efficiency. Fish bone plate design also reduces the pressure drop on the secondary side, making it possible to use a smaller pump and less electricity, lowering the overall cost of applications.
- PARAMETER -- Model: FHC030B-70-4.5, 1,023,000 btu/h capacity, 22.08 sq.ft heat transfer area, 5"x12"-70 plates with 1-1/4" port.
- APPLICATION -- Provides the highest level of thermal efficiency and durability in a compact lightweight unit, this water heat exchanger is ideal for domestic water heating, floor heating, snow melting, wort chiller, outdoor wood furnaces, solar heating, zone heating systems, industrial oil cooling, residential and light commercial HVAC hydronic systems.
- TRUSTED QUALITY -- Our brazed plate heat exchanger series have been certificated by UL.

## Questions & Answers

**Q: Does it come with a mounting bracket?**
A: No, it doesn't.

**Q: Where can I find the center to center dimensions for the nipple locations?**
A: The distance between the two port for the short side is 2.76", for the long side is 9.84". These dimensions are for 5"x12" series unit.

**Q: I don't understand what this heat exchanger does. Can you please explain how it is used and why?**
A: It is used for water to water heating or cooling application. Hot water enters from right top port(F1) and leaves from right bottom port(F2). Cold water enters from left bottom port(F3) and leaves from left top port(F4). You may need circulation pump if there are permitted pressure loss limits. It is small size, only 5" x 12 " size of plate with 4 ports 1-1/4" MNPT. We also has 3" x 8" with 4 ports 3/4" MNPT and 4" x 12" with 4 ports 1" MNPT.
Hope it can solve your questions.

**Q: How is this product intended to be mounted? Are there studs or tabs, or is a bracket required?**
A: It can be mounted right on the pipe or you can just strap on the wall. This unit have not brackets or studs that come with it.   But if you are using copper pipe to strapped up will be better.
