Most traditional tank water heaters last between 8 and 12 years, while tankless water heaters can last 15 to 20 years with proper care. Lifespan depends on factors like water quality, how hard your water is, how often the unit is used, and whether it has received regular maintenance. If your water heater is approaching the 10 year mark, it’s worth scheduling an inspection even if it seems to be working fine.
If your water heater is under 8 years old and the issue is isolated, such as a faulty thermostat or a leaking valve, a repair is usually the more cost effective option. If the tank itself is leaking, the unit is over 10 years old, or you’re dealing with repeat breakdowns, replacement typically makes more sense in the long run. During an inspection, we’ll give you an honest recommendation based on the actual condition of your unit, not just a sales pitch.
Tank water heaters have a lower upfront cost, are simpler to install, and work well for most households, which is why they remain the more common choice. Tankless water heaters cost more initially but heat water on demand, take up significantly less space, and typically last longer than tank units. The right choice depends on your household’s hot water usage, your budget, and how much space you have available for installation.
Installation cost depends on the size and type of unit you choose, the condition of your home’s existing plumbing, and the warranty and maintenance plan you select. Our installation plans start at $1,199 for a standard 40-50 gallon water heater, which includes both parts and labor along with a 6 year warranty. Higher tier plans add longer warranty coverage, included maintenance inspections, and discounts on future plumbing repairs. See the full pricing breakdown above for details on each plan.

A standard maintenance visit includes flushing the tank to remove sediment buildup, inspecting the anode rod for corrosion, testing the pressure relief valve, checking all connections for leaks, and verifying that the unit is running efficiently. We recommend scheduling maintenance annually. If you’re on our Silver or Gold installation plan, a yearly inspection is already included for the life of your warranty.
Yes, we regularly install and replace water heaters in older homes throughout Grove City. Older homes sometimes require additional work to bring plumbing or venting up to current code, and we’ll flag anything like that during our initial inspection so there are no surprises once the installation begins.
