What Is a Tankless Water Heater?

A tankless water heater, also known as an on-demand water heater, heats water only when needed instead of storing it in a tank. It provides endless hot water while using less energy than traditional tank models. Both gas and electric options are available to suit different home setups.

How Does a Tankless Water Heater Work?

When you turn on a hot water tap, cold water flows through a heating element or gas burner, instantly heating the water. Unlike traditional water heaters, there’s no waiting for a storage tank to refill. This system delivers a continuous supply of hot water without running out.

What Are the Benefits of a Tankless Water Heater?

Tankless water heaters offer energy efficiency, endless hot water, and a longer lifespan compared to traditional models. They also take up less space and reduce the risk of water damage since they don’t store large amounts of water. Over time, they can help lower utility bills by using less energy.

Is a Gas or Electric Tankless Water Heater Better?

Gas tankless water heaters generally heat water faster and work well for larger households with high water demand. Electric models are energy-efficient, easier to install, and ideal for homes without a gas connection. The best choice depends on your home’s setup, energy availability, and budget.

Do Tankless Water Heaters Provide Instant Hot Water?

While tankless water heaters heat water on demand, hot water may still take a few seconds to reach the tap, depending on the distance from the unit. Some homes use recirculation systems to reduce wait times. Once the hot water arrives, it continues flowing without running out.

How Long Do Tankless Water Heaters Last?

Tankless water heaters typically last 20 years or more, nearly double the lifespan of traditional tank models. Regular maintenance, such as descaling and flushing, helps extend their lifespan. Choosing a high-quality model and professional installation ensures long-term reliability.

Are Tankless Water Heaters More Expensive to Install?

Tankless water heaters have a higher upfront cost than traditional models due to installation complexity and required upgrades. However, they save money in the long run by reducing energy usage and lasting longer. Many homeowners find the investment worthwhile for the efficiency and convenience they provide.

Do Tankless Water Heaters Require Maintenance?

Yes, routine maintenance is important to prevent mineral buildup, especially in areas with hard water. Flushing the unit and descaling the heating elements once a year keeps the system running efficiently. Regular maintenance helps maintain performance and extends the unit’s lifespan.

Top notch service. On time, very professional. The crew was friendly, competent and respectful. They took extra care to ensure the work areas were clean and as little snow tracked in as possible. Hardwired smart-home smoke detectors were installed to specification and work perfectly.

Roy’s was amazing when our furnace bit the dust. They were able to get out same day and diagnose the problem an had a team out (on a holiday during a snowstorm no less) to come out and install the new unit. All of the employees we have worked with throughout the process have been extremely pleasant and respectful of our home. Hopefully no other huge jobs will be needed for a while but I appreciate their speed and service.
