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.

Josh B came to the house and was so helpful! Quickly found the cause of the leak and repaired it, didn’t try to nickel and dime me. On top of that he was very courteous, warned me of any loud noises so as not to disturb my baby, which was above and beyond. Would definitely trust him with a job again!

The service technician routed out the tree roots and got the sewage draining again in short order. He removed a ball of roots the size of a football with individual roots the size of a common pencil. Very happy with the results and care for our home. He even helped me move 50 individual gallon containers of water that were in the way of access for his machine. Very happy with the job preformance. But the cost was above $200/hour for emergency service.

Tom was fantastic! We've never had to call a plumber before because we are DIY'ers, so we were very hesitant. But we definitely made the the right choice! Tom was on-time, very knowledgeable and listened to all of my concerns before addressing the problem. When we need to add a bathroom we will be contacting Roy's to do the plumbing!
