How Long Do Water Heaters Typically Last?
The average lifespan of a water heater is 8 to 12 years, depending on the type of system and how well it’s maintained. Tankless water heaters can often last 15 to 20 years with proper care. Regular maintenance, like flushing sediment from the tank, can extend longevity.
When Should a Water Heater Be Replaced Instead of Repaired?
If your system is more than 10 years old, frequently breaks down, or shows signs of leaking, replacement is usually the smarter option. Our technicians can assess your water heater and let you know if repair or replacement is best for your situation.
Cost of Water Heater Installation & Replacement
Many homeowners wonder: how much does a water heater cost? While costs vary by size and type, replacing a standard 40-gallon water heater typically ranges between $2,000 and $4,500 including installation. High-efficiency or tankless models may be more, but they can save money long-term through lower energy bills. We’ll provide a clear estimate upfront so you know what to expect.
Water Heater Maintenance & Cleaning
Regular maintenance keeps your system running safely and efficiently. Knowing how to flush a water heater or how to drain a water heater is key to removing sediment buildup that reduces performance. For tankless systems, annual descaling ensures your unit operates at peak efficiency.
While some homeowners ask “Can I flush my water heater myself?” We recommend professional service to avoid damaging your system and to keep your warranty valid.
