8. 24" Side Arm Heat Exchanger Outdoor Furnace Boiler Stove - Sweat

Description

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. This sidearm has a 1-1/2" outer tube which is 20" long, this allows for a much easier installation between your hot water tank drain and the pressure relief valve. Overall the sidearm measures 24-1/4" 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. Our side arms are packaged the best possible way to minimize shipping damage. The side arms fit snuggly in the boxes to minimize movement within the box. The ports are surrounded in styrofoam all the way around to prevent damage if dropped. The entire side arm is packaged in a double wall, re-enforced cardboard box and taped closed. We do our best to offer a high quality product that will not be damaged during shipping and you will not have to return due to manufacturers defects such as leaking. We stand behind the exchangers with a LIMITED LIFETIME WARRANTY AGAINST MANUFACTURERS DEFECTS. Comes FULLY ASSEMLBED/PRE-SOLDERED and ready to install. PRESSURE TESTED to ensure a leak free unit. 1-1/2" copper on the outside w/ 1" copper sweat connections for the boiler input/output, 1-1/2" outside shell produces maximum efficiency with minimal pressure drop on boiler side. 3/4" sweat connections for the domestic water input/output. Will work with ANY existing hot water tank heater

9. 34" Fin Enhanced Side Arm Heat Exchangers

Feature

304 Stainless Steel
SideArm Heat Exchanger for Domestic Hot Water.
Designed with the natural thermo-siphon concept on domestic hot water side.
BTU-9500 ; Length- 34" ; Boiler Port 1" MNPT ; Domestic Port 3/4" MNPT

Description

High Quality Fin-Enhanced Sidearm Heat Exchanger is designed with the natural thermo-siphon concept on domestic hot water side. Traditional sidearms are made of two bare copper tubes. Thus, its capacity is decided by the length of sidearm-tubes and the heat transfer efficiency is very low. Made of 304 stainless steel, fin-enhanced sidearm increases heat transfer efficiency significantly by using a finned tube internally, which has surface area five to eight times bigger than bare tube and produces great turbulence on system side. With fin-enhanced sidearm you not only need a shorter unit, but get bigger capacity and faster heating. Due to the compact size and lightweight of the side arm heat exchanger, these units are ideal for residential heating and plumbing applications. Also called domestic water heat exchangers, these units are typically used to heat domestic water using either a conventional boiler, outdoor wood furnace or solar hot water system.
