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

When calculating the cost of a tankless water heater and the labor to install it, we consider the unit's flow rate and your home’s existing utility connections. Upgrading to this technology usually requires specific venting and plumbing modifications that impact the total price. We ensure the system is properly sized for your family’s water usage. Exact pricing confirmed free on the call.

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.
