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.

We evaluate your specific space to ensure the system is sized correctly for your household needs. Exact pricing confirmed free on the call.

Even though it is warm outside, your water heater is still working daily.
