Gas heaters usually recover faster and can cost less to operate where gas rates are reasonable. Electric units are simpler and do not require venting.
We install Rheem, A.O. Smith, Bradford White, Navien and Rinnai. We recommend models based on reliability, efficiency and warranty.
Common signs include a lack of hot water, rust-colored water, strange noises like rumbling or popping from the tank, or visible leaks around the base of the unit. Older units, particularly those over 10 to 12 years old, are also candidates for replacement.
