High Quality Fin-Enhanced Sidearm Heat Exchangers are designed with the natural thermo-siphon con-
cept on the domestic hot water side. Made of 304 stainless steel, fin-enhanced sidearms increase heat transfer
efficiency significantly by using a finned tube internally, which has a surface area five to eight times bigger than bare
tube and produces greater turbulence on the system 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. With fin-enhanced sidearms you not only need a shorter unit, but get
bigger capacity and faster heating.
Double walled fin-enhanced sidearms are available upon request. Due to concerns about cross contamination of po-
table water several US States enacted regulations to prevent this possibility from occurring. Double wall heat ex-
changers presented the most effective means of protection from cross contamination. We now provide a vented dou-
ble walled sidearm which meets the criteria of these regulations.
Due to the compact size and lightweight of the sidearm heat exchanger, these units are ideal for residential heating
and plumbing applications. Also called domestic water heat exchangers, they are typically used to heat domestic wa-
ter using either a conventional boiler, outdoor wood furnace or a solar hot water system. Typically, the domestic wa-
ter is circulated by means of the thermo siphon principle which saves on the cost of a pump and the associated elec-
trical costs. In cases where faster heat recovery is required. The domestic hot water should be circulated by means
of a pump. Pump circulation will typically provide a heat recovery 3 to 4 times greater than thermo siphoning.
