Copper Domestic Water Side Arm Heat Exchanger

READ BELOW TO FIND OUT WHY THIS SIDE ARM IS THE BEST ON THE MARKET!!!

Many sidearms have a tube within a tube only, these sidearms have multiple tubes within the exterior tube. By having the greatest amount of surface area it makes our sidearm the most efficient on the market.  MORE SURFACE AREA = MORE EFFICIENT = MORE HOT WATER & QUICKER RESPONSE TIMES  Most sellers use just a normal piece of 3/4" copper shoved down the center, OR they use a roll threaded type tube.

Our sidearm has a 1-1/2" outer tube and is 13" long, this allows for a much easier installation between your hot water tank drain and the pressure relief valve.  Overall the sidearm measures 17-1/4" long from end to end.  Because of the internal tube design you've actually got much more surface area than a traditional 48" sidearm.  The problem with long sidearms is that 99% of the time you have to plumb from the top of the sidearm down so far to the pressure relief valve that you lose the efficiency of the thermal syphon.  In a long sidearm like that the hot water rises in the sidearm as it is heated but the hot water does not easily drop down and back into the tank because hot water rises and cold water sinks.  If you have used the larger sidearms before you know exactly what I'm talking about.
