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.

I had a leaky faucet in the bathroom. Evan was my plumbing technician. He explained everything to me as to why this was happening. He then proceeded to let me know what was the best way to fix this issue. He also explained that the shut off under the counter was not working properly. He changed the faucet and replaced the 2 shut offs under the counter. Everything working properly now. Clean up completed. Before Evan did any work he explained and priced out all my options. Very through. Job completed very happy to have such a polite repair man that also respected my property. Thank you Roy’s Plumbing and Evan.

I woke up to a freezing house..thermostat reading 42°, the boiler cold & silent. I’ve used Roy’s in the past & from beginning to end everyone is always friendly and professional. From the woman who took the-initial call, caring enough to ask questions so she could schedule the technicians who had the expertise & experience working with older steam boilers. Mike & Gabriel diagnosed the problem,,replaced the part & had it up and running in no time at all. They were both , personable, professional, & knowledgeable.

All of the crew were very well mannered, educated in their craft, and completed the job in a timely fashion. It started out with a clogged sewer pipe and ended up with new piping.
