Vanward gas 6B water heater is a copper tube or aluminum tube?
Vanward gas water heater 6B practical model is JSD12-6B, is the flue type water heater, but also the state does not allow the use of gas water heater (as well as part of the rental housing in use, the reason is cheap, this is the old product), the Vanward factory has long been discontinued. The gas water heater began to use the oxygen free copper water tank in recent years, so the Vanward gas water heater is made of aluminum alloy water tank, not copper.
