Tankless Water Heater Installation in Jacksonville, FL

Tankless water heaters are a great way to create a more energy-efficient home. Unlike tank-style water heaters, which continuously heat water around the clock, tankless water heaters generate hot water instantly with high-powered gas burners or electric coils. This instant heating requires more power, but because the water does not have to be reheated again and again, like in a standard tank model, tankless systems use less energy overall. Our licensed plumbing experts at David Gray Plumbing can help you determine whether a tankless water heater is right for your home.

How Does a Tankless Water Heater Work?

Tankless water heaters provide hot water on demand, as opposed to storing water in a tank and heating it continuously throughout the day. Likewise, traditional storage tanks can run out of hot water when faced with back-to-back showers, laundry, or other household chores. Tankless units don’t have this problem, as they only provide hot water when you need it. This makes them not only a more convenient option but a more eco-friendly one as well, saving you substantial money on your monthly energy bill.

Benefits of Tankless Water Heaters

Tankless water heaters are gaining popularity throughout Jacksonville and the surrounding areas, and with good reason. They boast a ton of benefits, including:


  • Low operation costs: Storage water heaters experience standby heat loss by keeping 30 to 80 gallons of water hot around the clock. Tankless water heaters will heat your water on demand, allowing you to use only what you need.
  • Energy-efficient operation: By using less energy to heat your water, along with providing on-demand heating, tankless water heaters are by far the more energy-efficient option.
  • Longer life span than storage water heaters: Tankless water heaters experience, on average a service life that is around 20 years. Some last even longer with annual, preventative maintenance. That’s a huge jump compared to tank-style water heaters, which last between eight and 12 years.
  • Increased property value: Due to their energy efficiency and long service life, tankless water heaters are considered a strong investment for your home.
  • Smaller space required: Tankless water heaters are small and much less bulky than their tank-style counterparts.
  • Less risk of water damage: Because they do not store water and simply heat it on-demand, tankless water heaters pose no risk of water damage from a burst or leaky tank.

Frequently Asked Questions About Tankless Water Heaters

What size water heater do I need?

Household size, or the number of users, is a good indicator of what size water heater will best meet your needs. You also need a tank with a first-hour rating that meets or exceeds the number of gallons of hot water you need to cover all the activities that might take place simultaneously during the day. For instance, showering uses 20 gallons, washing dishes by hand uses 6 gallons, and running a clothes washer uses 30 gallons.

Is it worth it to switch to a tankless water heater?

The U.S. Department of Energy says a tankless water heater is more efficient and uses less energy than a conventional tank unit. Things to consider before investing in a tankless water heater include the higher initial costs and whether your home has the existing electrical capacity to use a tankless water heater.

How long do tankless water heaters last?

With proper maintenance, most tankless water heaters have a life span of 20 years or more. In comparison, a standard tank unit typically has a working life of 10 years or less.

How does a tankless water heater instantly heat water?

Whether you install a gas or electric unit, once you turn on a faucet, the water flow triggers the powerful interior burners or electrical heater to turn on. The water rapidly heats as it passes through the unit. How soon you receive hot water at the faucet depends on the distance it has to travel. When you close the faucet, the burners or elements shut down.

Can you run out of hot water with a tankless heater?

No, because a tankless system doesn’t have a supply of hot water that can be depleted. Tankless units heat water on demand and keep delivering a steady stream of hot water until it’s no longer needed.

Will a tankless heater save me money?

This can depend on multiple factors, but the general consensus is that you can save money by installing a tankless water heater. So, not only will you be helping the environment, but you’ll also save on your gas and electric bills.

Is a tankless water heater more expensive than a traditional one?

Though tankless water heaters typically cost more initially, your long-term savings can ultimately offset that cost, provided you select the correct size model from a reputable manufacturer. According to the Department of Energy, the average family can expect to save about $110 annually with a tankless model.
