What affects the price

Replacing your water heater involves several variables that change the final bill. The biggest factor is the unit type—tankless models usually cost more upfront than traditional tank-style heaters due to installation complexity. You also have to consider the fuel source, as switching from gas to electric often requires electrical panel upgrades. Size matters too; a larger home needs a unit with higher recovery rates. Finally, local building codes might require additional safety equipment, like expansion tanks or updated venting.

Frequently asked in Lexington-Fayette

How long do hot water heaters typically last?

Tankless water heaters generally last between 15 to 20 years, often longer with proper maintenance. Traditional tank water heaters typically have a lifespan of 10 to 15 years. Regular servicing can significantly extend their operational life and prevent unexpected failures.

What is the average cost of putting in a water heater?

What is the most efficient type of water heater?

Tankless water heaters are known for their high energy efficiency because they heat water only when it's needed. This on-demand system avoids the energy waste associated with keeping a large tank of water hot constantly. It's an excellent way to reduce utility bills.

What are signs I need a new water heater?

Watch for signs like inconsistent hot water temperatures, unusual noises, or visible leaks. If your unit is older than 10-15 years and exhibiting these symptoms, it’s a strong indicator that replacement might be the best course of action. Don't wait for a complete breakdown.

What is the most common problem with a hot water heater?

Common problems with tankless units include mineral deposits, which can affect water flow, and issues with the electronic ignition or fan. For tank heaters, sediment accumulation and anode rod corrosion are frequent concerns. Both types can experience thermostat malfunctions.

Is it worth it to repair a hot water heater?

Repairing a water heater is often a cost-effective solution, especially for newer units or less severe issues. A qualified professional can assess the problem and advise whether a repair is more economical than a full replacement. Obtaining a repair quote is the essential first step.
