How Does a Tankless Water Heater Work?

The development and spread of tankless water heaters has given homeowners the advantage of always having enough hot water to meet their needs. Where the standard storage water heater keeps a standby tank of water ready for use that can run out before more water can heated up, a tankless system is an “on-demand” water heater that heats up water as it is needed, and therefore has no supply that can run out. Tankless systems also use less energy and will pay for their installation after a couple of years.

Despite all their advantages, tankless water heaters will not work ideally for all household. Call the Maitland, FL water heater experts at Modern Plumbing Industries, Inc. (MPI) to schedule an appointment to learn more about how well one of these advanced home comfort system will work for you.

The Operation of a Tankless Water Heater

People often initially find the concept of a water heater without a tank to be strange and hard to understand. But tankless water heaters are not terribly complicated.

The basics of a tankless system is a heat exchanger that transfers heat from a power source (either electric or gas) to the water in the pipes. The exchanger in the tankless water heater turns on whenever water starts to flow through the heater. A whole-house tankless water heater is connected onto the water main, so all water entering the home must pass through the system. Whenever your turn on a hot water tap, water begins to flow and the heat exchanger comes on, heating up the water as you need it.

There is one drawback to this, which you might have noticed from the description: there is a delay between the when the water receives heat from the heat exchanger and when it reaches the tap. For larger houses, the lag can be greater for a tankless water heater than it would be for a standard storage system.

Tankless systems are also available in point-of-use models, smaller units that attach to individual taps. They have little lag time, and in some cases are more cost-effective.

Tankless water heaters need professional installation. When you call up the experts at Modern Plumbing Industries, Inc. (MPI), we will help you determine if a tankless water heater in Maitland, FL, whether whole-house or point-of-use, is a good choice for you based on your hot water needs, the number of people in your home, and your budget plans.
