Reasons to consider a Tankless Water Heater

September 25, 2013

Tankless water heaters revolutionize the way you use hot water. They produce more hot water, at a more consistent temperature, using less energy than typical tank-style water heaters.

Take a closer look at why tankless might be right for you:

1 Save money

Because tankless water heaters provide hot water only when it’s needed, they can save you up to 40%* on your energy bill. They feature Energy Factors of 0.82 up to 0.96, while tanks are typically 0.60.

* As based on the average cost to run an electric tank water heater per the DOE Average Energy Costs (http://www.doe.gov).

2 Continuous Hot Water

Tankless hot water heaters do not store a large volume of hot water that can be depleted, but rather heat the water as it’s being used, giving you endless comfort in the form of continuous hot water at a consistent temperature. You can even use hot water for multiple tasks—such as showering, washing dishes or doing laundry—at the same time without worrying about running out.

3 Save space

Traditional tank water heaters can take up to 16 square feet of valuable floor space. Tankless water heaters, however, are a fraction of the size and can be installed on virtually any wall, indoors or outdoors.

4 Longevity

Tankless water heaters have a typical life expectancy of up to 20 years—twice as long as a tank-style unit.

5 Green

Many tankless gas water heaters have earned ENERGY STAR® approval by meeting the strict energy efficiency guidelines set by the U.S. Environmental Protection Agency and the Department of Energy.

Frequently Asked Questions

1 Is a gas tankless water heater or an electric tankless water heater better?

An electric tankless water heater generally cannot deliver hot water fast enough to replace a conventional gas water heater if groundwater is too cold. Even in areas with warmer groundwater, most homeowners would need to upgrade their electrical service to supply the necessary amperage for a whole-house electric tankless water heater.

2 What size will I need?

The ideal size of your tankless water heater will depend on the number and type of plumbing fixtures and appliances you have, and the groundwater temperatures in your area. It will also depend on how many people are in the household and how they use the hot water.

3 How is temperature controlled?

A typical tankless water heater comes with a temperature controllerthat you use to adjust the water temperature (within a safe range, typically from 98° F to 140° F). The controller also displays diagnostic and maintenance codes to help you monitor system performance.

4 Can I use my existing venting?

No. You will need to use the approved venting specified by the manufacturer of the tankless water heater. Some manufacturers offer concentric venting, which only requires a single wall penetration for both the intake and exhaust and has a zero clearance to combustibles.

5 What maintenance is required?

Typically, there are two types of simple, periodic maintenance that you or your service technician should consider to keep your tankless water heater running optimally: Checking the in-line screen filter for debris; and flushing the tankless water heater to keep it free of scale and lime.

6 Can I install it myself?

Installation should be performed by Jim Lavallee Plumbing, Inc. , we are trained to handle the plumbing, gas, electrical and venting aspects of a tankless water heater, and is aware of all local and national codes. Having a non-licensed professional perform the installation could affect the product warranty should there be operational or performance issues which are caused by improper installation.

7 How much does a tankless water heater cost?

A tankless water heater will typically cost two to two-and-a-half times as much as a conventional tank-style water heater. However, energy savings and lifestyle benefits make it a better long-term investment over a tank.
