Frequently Asked Questions About Water Heater Repair in Mercer, WI

Hard water is very tough on tankless heaters because the intense heat causes calcium to rapidly build up inside the narrow heat exchanger. You must have your tankless unit descaled annually to prevent irreversible damage.
Yes. Sediment creates a thick layer of insulation between the burner and the water. The burner has to run longer and hotter to heat the water, which overheats and weakens the steel tank bottom, eventually causing it to fracture.
A good rule of thumb is the 10-year mark. If your tank is less than 10 years old and the issue is a faulty part (like a thermostat or element), repair is usually best. If the tank itself is leaking from the bottom due to rust, a full replacement is required.
An anode rod is a crucial component that attracts corrosive elements in the water. It rusts so your steel tank doesn't have to. You should have it checked every few years and replaced before it completely dissolves.
Tankless water heaters are an excellent upgrade if you want endless hot water and lower energy bills. They heat water only when you need it and take up much less space, making them a popular choice for homes in Mercer, WI.
