Tankless Water Heaters

Columbus Tankless Water Heater Service

Storage water heaters have long been considered conventional water heaters as they have been around for about a century and are used by the majority of homeowners. Tankless technology has existed almost just as long, and has experienced a tremendous boom in popularity over the past few decades, thanks to the many benefits they offer.

Tankless water heaters provide hot water on demand, meaning they heat water whenever a hot water tap is turned on across the whole house. The capacity of tankless models is represented by flow rate, measured in gallons per minute (gpm). Natural gas tankless water heaters and electric tankless water heaters are available, depending on the fuel type available through the home.

Unlike storage tank water heaters, they do not preheat cold water and hold it in a standard tank. The heat exchanger of a tankless water heater only turns on when the flow sensor detects the need for heating water – their design eliminates standby energy losses to reduce energy costs. Without a tank, tankless units save space in the home – many on demand water heaters require minimal floor space or can be installed on a wall to eliminate the need for floor space altogether.

While installation costs can be higher compared to installing a conventional water heater, the energy savings tankless water heaters produce while providing a constant supply of hot water leads many homeowners to choose tankless models when replacing the home’s water heater.

Why Choose Electric Tankless Water Heaters and Gas Tankless Water Heaters?

Tankless water heaters are becoming more and more common in Columbus, Ohio area homes, replacing tank conventional water heaters that have been popular for many years. Whether your home currently has a storage tank water heater or you have a tankless water heater, there are many reasons to replace your system with an energy efficient electric model or natural gas tankless water heater.

The many benefits of tankless water heater installation include:

  • Tankless water heaters heat water reliably whenever it is needed in the home. How much hot water is created depends on flow rates and the volume of hot water needed to supply taps throughout the house. Flow rates are expressed in gallons per minute gpm, which expresses the capacity to produce hot water for every point of use simultaneously, from using the dishwasher to taking showers. If you have many family members living under a single roof, tankless water heaters with higher flow rates are preferred versus smaller units as they produce more hot water gallons per minute to ensure there is enough hot water for multiple uses at one time.
  • Tankless units are also called on-demand water heaters because they only heat water as it is needed. When you have hot water flowing through a faucet, it was not stored in a tank – the heating elements just heated incoming water before it was sent through water pipes to your fixture. By forgoing the storage tank method of water heating, a tankless water heater can improve the energy efficiency of water heating up to 35%.
  • Gas tankless water heaters, as well as electric tankless water heater units, offer greater energy efficiency versus conventional water heaters. Tankless units are as much as 40% more energy efficient than conventional water heaters fueled by natural gas, and as much as 55% more energy efficient than conventional electric models.
  • With regular maintenance, a tankless water heater offers a much longer useful life than a conventional water heater. You can expect tankless water heaters to last around 20 years, while storage tank models only last about 10 years.
  • Tankless water heaters are a safer choice versus storage tank models running off electricity or natural gas. A tankless unit does not constantly consume natural gas or electric power to maintain stored hot water temperatures in the tank. Safety features that monitor flow rates and water pressure can detect malfunctions and failures in the system and automatically turn the unit off to prevent damage and Hazards.
  • Because there is no storage tank, the risk of a catastrophic leak is less likely with a tankless water heater. If a storage tank ruptures, it can flood the whole house with many gallons of hot water. While tankless water heaters can form leaks if not well cared for, water damage and flooding are not as severe.
  • The size of a tankless water heater is more convenient in homes where space is at a premium. Because of its small footprint, a homeowner will have more options when it comes to installation location compared to water heaters with tanks.

How to Choose a Tankless Water Heater

Heating hot water is responsible for about 14% of the average home’s total energy consumption throughout the year. The water heater you use will have a noticeable impact on the amount of energy it takes to produce the hot water your family needs. If you are considering converting to a tankless water heater from a tank model or are ready to upgrade your existing tankless water heater unit, here are some important factors to keep in mind as you select a new unit for installation.

Installation Cost

Purchasing a new tankless water heater will cost you more than buying a tank style water heater. However, don’t be put off by the upfront cost of these models, as other considerations can make up for the difference. Tankless water heaters last twice as long as models that have tanks, meaning you won’t have to replace them as frequently. They’re also more energy efficient and cost less money to operate. The savings regarding operation and replacement can more than make up for the difference in cost between a tankless water heater and conventional storage water heaters.

Fuel Type

The heating elements that activate to heat cold water coming through pipes in the house are powered either by electricity or gas. Before selecting a new tankless water heater, you need to consider the fuel sources available for use with the system. Installing an electric tankless water heater increases the demand on the home’s electrical system and may require electrical upgrades to handle the larger load. Electricity is also more expensive in some areas than natural gas. Tankless water heaters with a gas heat exchanger are generally considered to be more powerful than electric tankless water heaters and are often preferred in homes with natural gas access or a liquid propane tank.

Flow Rate

To make sure your household has enough hot water when using a tankless water heater, you need to determine how much hot water you need to heat to supply every use that can go on at once in the home. If multiple family members are taking showers while the dishwasher runs, units with higher flow rates will help ensure the hot water demand is met at a comfortable temperature.  If the flow rate of your tankless water heater is not high enough, there will not be enough hot water to perform every activity comfortably at the same time.

Do you know how much hot water is consumed by various uses in your home, like running a faucet for bathroom or kitchen sinks, dishwasher, or showers?

  • A faucet uses 0.75 gpm to 2.5 gpm
  • Showers with low-flow showerheads require 1.2 gpm to 2 gpm
  • An old standard showerhead consumes 2.5 gpm to 3.5 gpm
  • Laundry washing machines and a dishwasher need 1 gpm to 2 gpm
