Frequently Asked Questions About Water Heater Replacement in Janesville
Most standard gas or electric tank replacements cost $1,400 to $3,000 including the heater, labor and typical code upgrades. Attic installs, larger tanks or relocations can raise the cost to $3,000 to $4,500.
HKV Plumbing installs and services all major brands, including Bradford White, Rheem, AO Smith, Rinnai, Navien and State Water Heaters. We can help you choose the best brand and model that suits your budget and hot water demands.
Leaks at the base, rusty water, rumbling noises, inconsistent hot water and an age over 10 years are common signs. A leaking tank should be replaced right away.
Choosing the right size depends on the number of people in your household, their hot water usage habits and peak demand times. Our technicians will calculate the appropriate GPM (gallons per minute) for tankless or gallon capacity for tank models so you never run out of hot water, especially in multi-bathroom Janesville homes.
Most replacements take two to four hours. Attic installs or relocations can take more time.
Most new water heaters come with a manufacturer's warranty ranging from 6 to 12 years on the tank and components, depending on the model and brand. HKV Plumbing also provides a labor warranty on our installation, so your investment is protected.
Flushing a traditional tank water heater once a year is recommended in most homes. Hard water is common across much of Wisconsin, especially where supply comes from groundwater moving through limestone and dolomite. This helps remove sediment buildup, which can reduce efficiency and shorten the lifespan of the unit. Regular flushing can also prevent scale from impacting heating elements.
Common signs include a lack of hot water, rust-colored water, a metallic taste in hot water, strange noises like rumbling or popping from the tank, visible leaks around the base of the unit or a water heater that is over 10 to 12 years old. If you notice any of these, it is time to call a licensed plumber.
