What Is a Tankless Water Heater?

A tankless water heater provides you with hot water on demand. This means you get a continuous hot water supply without paying for heating and storing water in a tank. Tankless units are a great choice in California due to their compact size and long-term durability and reliability.

How Does a Tankless Water Heater Work?

Water passes through a heat exchanger in the unit and comes up to temperature with a gas burner or electric heating element.

Choosing the Right Size for Your Home or Business

What size tankless water heater do you need? Right-sizing is critical. Too small and you risk running out of hot water at peak demand. Too big and you’re spending more than you need for installation and monthly energy bills. 

Call the professional water heater experts at Payless Water Heater & Plumbing and we’ll make sure you get the right fit. As a general rule of thumb, you want to consider how much water you’re using at any one time and ensure your unit can handle the flow rate to provide a continuous flow of hot water.

Don’t Risk DIY: Leave It to the Professionals

When it’s time to repair, maintain or replace a tankless water heater, don’t try DIY. The risk of safety hazards is high, especially if you’re working with gas. You could damage the unit or create leaks. It may also void any warranty you have on the unit and lead to expensive repairs after the fact.
