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.

What are the pros and cons of a gas water heater?
Gas water heaters in Thornton are generally less expensive to operate than electric models due to the cost of natural gas. They also tend to heat water more quickly. However, they require a gas line and proper ventilation, which can limit installation locations.
What are the most energy efficient water heaters?
