Review: good quality works well and good price Review: excellent inexpensive heat exchanger - I use this exchanger to heat small quantities of water (about 1 gal at a time) to serve my routine hand washing and even bathing (ex. Geyser system) using a single burner backpacking type propane burner and small 12v diaphragm pump to have water circulate through the exchanger. the efficiency of heat extraction is amazing -- I can have a moderate burner flame under the exchanger (pump ON of course to circulate water -- NEVER DO THIS WITHOUT HAVING CIRCULATING WATER -- think of this as a mini nuclear reactor setup where you never expose the core!) and put my hand just above the exchanger and it's barely warm so I'd estimate >90% heat extraction efficiency. I typically heat up the water to about 120F and this serves me for most routine hot/warm water needs. VERY WATER CONSERVING especially if you "boondock" with an RV. I also bought as a comparison the Dracaena 120mm - 28mm/1.1 inch Thick Computer Radiator, 14 Tubes Copper Water Cooling heat exchanger. this is much more expensive but I think is higher quality (weighs about 50% more for the same 120mmx120mm size) and it has 14 tubes instead of 12 tubes like this cheaper model. note that the fin spacing on this model is VERY TIGHT which may partly explain it's excellent heat transfer. I think it's a very good heat exchanger especially for the price. the port fittings are also integrated into the construction -- the more expensive model requires separate "plugs" for the ports.
