Washington, UT, Gas Water Heater FAQs


Most gas water heaters run efficiently for eight to 12 years. With regular maintenance from Thompson, many systems last even longer while keeping energy costs down.

This largely depends on the availability of natural gas at your property. As long as this utility serves your home or business, we should be able to handle it. Converting to a gas water heater typically involves installing gas line connections, testing for leaks, and ensuring proper ventilation.

Most homes with one to two people do well with a 30- to 40-gallon tank, while families of three to four often need 40 to 50 gallons. Larger households of five or more people benefit from a 50- to 80-gallon gas water heater for a steady hot water supply.

Our kitchen sink would never completely drain so I called and made an appointment. I got an appointment the next day to have the issue diagnosed. The problem was diagnosed quickly and resolved quickly as well. Very impressed with the whole process and would recommend to anyone to use them. Also, very reasonably priced!
