## Features

- Efficient Heating: Our side arm heat exchanger is composed of highly conductive stainless steel, 38" in length and can dissipate up to 22,500 Btu's of heat per hour, capable of heating up to a 60Gal tank.
- Optimised and Upgraded: Compared with the traditional ones, our side arm heat exchanger is made of highly conductive stainless steel, which can heat up quickly and evenly; the internal finned tube is used to expand the heat exchange area inside the heat exchanger (5-8 times bigger than bare tubes), with high efficiency and low loss to maximize the heat exchange efficiency.
- Convenient Installation: The ports are standard FNPT threads, 3/4 "FNPT tube (Tank side/Cold water) and 3/4 "FNPT Shell (Water heater side/Hot water), the threads are deep and clear, and the installation is faster.
- Thermo-siphon Circulation:Compared to conventional ones, our side arm heat exchangers are designed to circulate using the natural thermo-siphon principle on the domestic hot water side, which saves on pumps and associated electricity costs; on this basis it only takes 3.8 houres to heat a 60Gal tank.
- Wide application:Our heat exchangers have a small, space-saving design and slim shape . Widely used in hot water tanks, domestic hot water heating, outdoor wood furnace, solar hot water heating and residential plumbing.

## Questions & Answers

**Q: Can this be connected to an AC condenser to chill water? Main concern is the pressure of the refrigerant.**
A: You need to do the calculations to determine the pressures that will be developed and at what temperature. Good news is the major heat pump manufacturers are all developing air to hot water systems. They should be available in the next few years.

**Q: does this model  come in a 1 inch also or just 3/4?**
A: Hi, My Friend 
The model FES115 comes in 1" FPT and the Asin No for  model FES115  is B08JC9VLCV, please check if it meet your requirements. Thanks

    Great product no problems
  

*by A***N on Reviewed in the United States on October 31, 2019*

It's often a problem to get dislike medals to thread together well. I'm a professional plumber and as like most professional plumbers will use pipe dope and a Teflon tape. I tighten up all 4 3\4 male adapters into this unit and had no leaks with any of them.  Seems to be an excellent unit a great price love the fact that it's all stainless steel have had to copper ones  Corrode and leak.

    Workmanship is lacking.
  

*by M***. on Reviewed in the United States on March 5, 2018*

The threads in the fittings are not completely cut to depth and were rough. Could not get either end to seal, until I had the fittings silver soldered, for the third installation.
