Question

I want to buy water heater jacket, I have a normal sized water heater, gas, in my garage. what do I need to know before I go buy one and where to I go to buy it ? And why do they ever put the water heaters outside where it is so cold, why don;t they put the in the house ??

Answer 1

simply measure the overall height of your tank, and the diameter of the tank. When you go to purchase the jacket, they will list the sizes of tank onto which the jacket will fit. They use small jackets for 30-40 gal, larger for 50 gallon, however, the new low profile tanks require the measurements to be known prior to going to Lowes' or a Home Depot.
