Water heater replacement questions
How much does it cost to replace a water heater?
A tank water heater replacement typically costs about $882–$1,826, with a 50-gallon gas tank often $1,600–$2,800 installed. Gas tankless systems usually cost $3,000–$5,500 installed.
Is a tankless water heater worth it?
Tankless units cost more up front but provide endless hot water and use energy only when water runs. They make the most sense for households that use a lot of hot water and plan to stay in the home for years.
Repair or replace my water heater?
Repair thermostats, elements, anode rods and valves on a younger heater. Replace it if the tank itself leaks, or if an older unit keeps needing repairs.
