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.

Frequently asked in Billings
What is a tankless hot water heater?
A tankless hot water heater heats water only when you need it, unlike traditional tank models that store and continuously heat water. When you turn on a hot water faucet, cold water flows through the unit, and a powerful heating element instantly warms it to your desired temperature. This provides an endless supply of hot water and can be more energy-efficient, as there are no standby energy losses associated with keeping a tank of water hot. This is a key benefit for Billings households.
What is involved in tankless water heater and installation cost?
What makes a water heater energy efficient?
An energy-efficient water heater uses less energy to heat and maintain water temperature. For tankless models, this means heating water only when needed, eliminating standby heat loss. Look for units with a high Energy Factor (EF) or Uniform Energy Factor (UEF). Proper sizing for your household's demand is also crucial. Efficient units often have advanced burner technology or improved insulation. Choosing an energy-efficient model can lead to significant savings on utility bills in Billings.

How does an on-demand water heater work?
An on-demand water heater, also known as a tankless unit, heats water only when there is a demand for it. When you turn on a hot water faucet, cold water flows through the unit. A powerful heating element, either gas or electric, instantly heats the water to your set temperature. The unit continues to heat water as long as the faucet is open. Once the faucet is turned off, the heating process stops, conserving energy.
What are the benefits of a gas water heater?
Gas water heaters typically heat water more quickly than electric models and can be more economical to operate in areas where natural gas is readily available. They require a gas line connection and proper venting to safely expel combustion byproducts. Modern gas water heaters are designed with safety features and improved energy efficiency. For many households in Billings, a gas water heater provides a reliable and robust solution for consistent hot water supply.
