Tankless Water Heater Pricing
As of 2026, most tankless water heater installations are typically $6,500 to $8,500+. Prices can fluctuate with today’s economy and vary from company to company based on overhead, venting, gas line sizing, electrical work, location of the unit, and what is included.

Common Tankless Questions
-
Tankless systems typically last 15–20 years with proper maintenance, much longer than traditional tank models
-
Yes. Because they only heat water on demand, tankless units are more energy-efficient and can reduce monthly utility bills. Unlike traditional water heaters that continuously maintain a reservoir of hot water, tankless systems activate only when hot water is needed, minimizing energy waste.
However, to maintain optimal performance and prevent issues such as mineral buildup, annual upkeep like de-scale service is required. Regular maintenance ensures the unit remains efficient and extends its lifespan, ultimately providing reliable hot water and cost savings over time.This service be DIY or professionally done starting at $300 each time.
-
The best tankless water heater is usually the one that is reliable, properly sized, and easy to support over the long haul. We often lean toward Rinnai because it is an established brand with strong technical support, available service resources, and a broad installer/service network. Since tankless systems need ongoing maintenance, we put a lot of value on choosing a unit that can actually be serviced and supported years from now.
-
It depends on the home and what you value most. Tankless water heaters can last longer, use less energy in many situations, and provide continuous hot water when they are properly sized. Traditional tank water heaters usually cost less up front and can be the simpler choice in some homes. DOE says tankless units are generally more energy efficient, especially in homes that use less daily hot water.
-
Yes, in most cases they should be flushed regularly, and annual flushing is a good baseline. Rinnai says mineral deposits should be flushed out at least once a year, and more often may be needed depending on water quality and usage. Regular maintenance matters because scale buildup can hurt performance and shorten the life of the unit.
-
Sometimes yes, but not always. It depends on the size of the home, how many fixtures may run at the same time, groundwater temperature, and the flow demand during peak use. DOE says proper sizing is critical for tankless performance, so a unit that is too small may struggle if multiple showers, laundry, and dishwashing happen at once.
-
A tank-style water heater is typically flushed by turning off power or gas, allowing the unit to cool, connecting a hose to the drain valve, draining water from the tank, and flushing out sediment. Tankless units are different and usually require isolation valves and a cleaning solution to descale the heat exchanger. If the unit is older, neglected, or not draining properly, it is safer to have it serviced professionally. DOE recommends regular maintenance for storage heaters, and Rinnai recommends at least annual flushing for tankless units.
-
Tankless water heaters can be a larger investment than a standard tank replacement, especially when venting, gas, condensate, recirculation, or code updates are needed.
