Rinnai tankless water heater — Columbia, MO
Last updated: September 24, 2026
What affects the price
When you are looking at the price of a new water heater, a few main things shift the final number. The type of unit you choose—whether it is a tank model or a tankless system—is the biggest factor. You also have to consider the fuel source, like gas or electric, and the physical space where the heater sits. If your home needs new venting, updated piping, or a different hookup to meet current safety codes, that adds labor time to the project.
About this service
A Rinnai tankless unit heats water only as you use it, rather than keeping a large tank hot all day. This is a great choice if you want to save space and avoid running out of hot water during back-to-back showers. Because these systems are complex, professional installation is necessary to ensure proper venting and gas flow.
Even though it is warm outside, your water heater is still working daily. Summer is a great time to adjust your settings, as the incoming water isn't as cold, which can actually help extend the life of your unit. If you are planning a home renovation or just want to upgrade to a more efficient model, call us to talk through your options.
