If your water heater is under 10 years old and the problem involves a replaceable component—such as a heating element, thermostat, thermocouple, or relief valve—repair is usually cost-effective. However, if the internal tank has rusted through and is leaking from the base, replacement is necessary.
Yes. Converting requires evaluating your gas line diameter or electrical service panel capacity, rerouting water supply lines, and installing proper direct venting. Our specialists handle the entire conversion seamlessly.
Yes! Tankless water heaters heat water on demand, saving 25% to 40% on energy costs while freeing up valuable square footage. They eliminate standby heat loss and provide a continuous, endless supply of hot water for large households.
We recommend an annual sediment flush for conventional storage tanks in St. Thomas, MO, especially in areas with moderate to hard water. Tankless units should also be descaled once every 12 to 18 months to protect the copper heat exchanger.
