How Does a Tankless Water Heater Work?

Unlike traditional tank water heaters, tankless models work by creating hot water on demand. The traditional versions hold your hot water in a tank, keeping it heated even when you aren’t using it. A tankless water heater heats your water on demand, so you have hot water soon after turning on the faucet.

Why Choose Tankless?

  • There are several amazing benefits to replacing your traditional water heater with a tankless water heater. Here are just a few of our favorites.
  • Your hot water will never run out.
  • You can run several different appliances at the same time without worrying about water running cold.
  • Takes up less space.
  • Environmentally friendly.
  • Lowers the risk of flooding.
  • .Water bills are lower.
  • Energy bills can be reduced by as much as 30% each year.
  • Since it doesn’t heat water until you turn on the hot water faucet, there’s no wasted energy from constantly heating unused water.
  • Last longer than traditional tank models.

These are just some of the best reasons to ditch the traditional water heater and switch to a tankless water heater.

How Long Do Tankless Water Heaters Last?

As we’ve said a tankless water heater can outlast the traditional version. How much longer does it last? That depends on how well you take care of it.

Most models will last at least 15 years while tank models will usually last about 10 years, often less. If you perform routine maintenance, like changing the heating exchanger when needed, you are looking at a unit that can last you well over 20 years. Repairs and maintenance costs are a lot less expensive than replacing a water heater or repairing damages caused by failing water heaters.

Models and Sizing Options

Any homeowner can enjoy the endless benefits of having a tankless water heater, you just have to know which model and size is the right one for you. With our experts, choosing the right Greenville tankless water heater services is easy.

Model Types

There are three basic types of tankless water heaters. For instance, your choice depends a lot on how much you want to save on installation, energy, and water costs.

  • Non-Condensing– Using a single heat exchanger, these tankless beauties reach an EF (efficiency factor) of around .83. They have been around for decades and are very reliable. A stainless steel vent system is needed for heat exhaust, which can get expensive. Efficiency goes down if your hot water is used mostly for short term things like washing your hands.
  • Condensing: Using both a primary and a secondary heat exchanger, these models have an even higher EF rating of around 92-94%. This means they have a much cooler exhaust and the venting system will be less expensive. Also, not as efficient for short term use.
  • Condensing Hybrid- This newer version hasn’t been around as long and has an EF of anywhere between .92 and .96. They use a small holding tank that holds around 2 gallons of hot water to keep on hand for short hot water usage. The venting system is inexpensive, so you can save costs on installations and on use!


Now that you know the model options, you’re probably wondering about sizing. Our team of skilled technicians will help you find the right model for your home by looking at three things.

  • How Many Faucets and Showerheads Do You Have?-The more shower heads and faucets needing hot water will require a larger model. If you don’t often use the faucets and showerheads at the same time, a small model will work for your home.
  • Calculate Flow Rates- How fast does water come out of your faucet or shower? You’ll need to add up all the rates or have our plumbing professionals help you find the right rate. After that, the flow rate lets you know the kind of demand you will put on your new tankless model. Most homeowners are looking for a rate of around 3.26. Not sure what a flow rate is? That’s what Greenville Plumbing Pros are here for!
  • Find the Temperature Rise- This is where you calculate how hot you want your water to get. Every family is different. Some households prefer piping hot water, while others want to keep those temperatures down. The temperature rise is a calculation of how many degrees you’ll need to increase the temperature.

Does it seem overwhelming? Don’t worry. The experts at Greenville Plumbing Pros will make these calculations for you and help you make the right choice. We will walk you through the process and make sure you find the perfect fit.
