More and more homeowners are choosing a tankless water heater over their outdated conventional models, and for good reason. Tankless water heaters offer countless benefits over their older, clunkier brother – the conventional water heater. However, there are also a few limitations to consider. If you intend to invest in a new water heater, it makes sense to understand the pros and cons of the system. We’ll walk you through the basics of a gas-powered tankless water heater.

What is a Tankless Water Heater?

First and foremost, you must understand just what a tankless water heater is and how one operates. Utilizing an “on-demand” water heating method, these systems have grown in popularity over the years due to their high energy efficiency and compact design. A tankless system can be installed virtually anywhere with space in your household.

A conventional water heater is designed to store hot water. It utilizes energy throughout the day to keep an adequate supply of hot water while not in use. It’s a drain on your finances. A tankless system will only use enough energy to heat water when necessary.

Benefits of a Tankless Water Heater

The reason why any homeowner would purchase a tankless water heater is for the benefits, which include:

  • Eco-friendly
  • Energy efficient
  • Compact design
  • Easily repairable
  • Constant supply of hot water
  • Extended lifespan

You no longer need to limit your shower time. There are no more age-related issues like leaking. And furthermore, the compact design makes installation a breeze.

Selecting a Tankless Water Heater

When it comes to choosing the right tankless water heater for your home, sizing is your number one priority. If you get the size wrong, you’re wasting money or losing out on your hot water supply. If you’re unsure of how to size a tankless hot water heater, call an expert. The professionals at bluefrog Plumbing + Drain of Phoenix-Scottsdale have more than enough experience to properly size your new water heater and perform water heater installation and repair when necessary.

Some factors to help you choose the right model are:

  • Energy Savings/Efficiency – Your energy savings are the top benefit of switching to a tankless water heater. It’s a factor you must closely consider. Water heaters use an Energy Factor (EF) rating to measure their efficiency. The higher the EF rating, the more efficient the system.
  • Warranties – Choosing the right warranty for the job is crucial. Warranties vary from manufacturer-to-manufacturer. Most manufacturers offer a warranty of 10 to 15 years for the heat exchanger, 2 to 5 years for parts, and 1 year for labor.
  • Sizing – As a general rule, your tankless water heater should deliver 2 to 5 gallons of hot water per minute. Think in terms of flow. For example, 8 gallons per minute is pretty standard.
