Homes need to have a water heater if they want to use hot water for showering, washing clothes, washing dishes, or cleaning. Tankless water heaters are becoming more in more popular in homes as their water heating source because of their smaller size and ease of installation. 

Before installing a new water heater it is typical for homeowners to have questions. In this blog, we will answer some of the most common questions about tankless water heaters. These answers should help you determine if a tankless heater or a traditional heater is better for your needs. 

1- How Does A Tankless Water Heater Work?

Understanding how a tankless water heater works is the best way to know if one is right for your home. The biggest benefit of tankless water heaters is they heat water on demand. As soon as your tap is turned on the water heater heats water and pushes it through the pipes. Once the tap is off, the burners inside the heater turn off to save you energy. 

Questions about tankless water heaters also include thoughts on how they compare to tank-style heaters. Traditional tank heaters constantly are pulling energy to have hot water on hand. Instead of heating water while you are not using it, tankless heaters only produce what you need.

2- Do Tankless Water Heaters Run On Gas Or Electricity?

Both gas and electricity can be used to run a tankless water heater. The majority of tankless heaters run on gas because it takes far less time to heat up. Some electricity is required to run the water heater as well, but the gas is what is used as the heating element for the water. 

3- What Size Heater Do I Need To Fit My Needs?

Finding a water heater to fit your needs is one of the most common questions about tankless water heaters that plumbers get. This question is important because running out of hot water is never fun. You will want to consider how many people are living in the home, what demands they have, how many bathrooms are in the home, and how big your home is when purchasing a tankless water heater. 

Everyone is unique and their water usage can vary, so working with a plumber or other expert can help you choose the right size and type for your home. 

Water heaters produce gallons of water per minute, which can help you determine what kind of size will be needed if you have a larger home. Some typical water production options for tankless water heaters include 6.5 GPM, 9.8 GPM, and 11 GPM. Some tankless heaters can be used for your entire house if they can keep up with simultaneous hot water demands. 

4- How Long Do Tankless Water Heaters Last?

Because tankless water heaters are more energy efficient, they can typically last longer than heaters with tanks. The average lifespan of a tankless heater is 20 years. When any plumbing mechanism is properly maintained, it can last for much longer. Typically, tank-style water heaters last for 10-15 years, so installing a tankless water heater will save you money not only on the amount of energy you use but also on heater replacement costs. 

5- What Maintenance Do Tankless Heaters Need?

All plumbing should have regular maintenance if you want it to keep running properly. Tune-ups are vital to keeping your water heater running smoothly. It is recommended that all water heaters be flushed and inspected at least once a year. This will help to flush out any sediment or bacteria that may have accumulated. This not only helps your water to stay safe but also improves the performance of the water heater. 

If your water heater is on the outside of your home, it may need some external cleaning or dusting to ensure that they work. Fans and filters may need to be cleaned or replaced to prevent the system from overheating.

Purchasing an energy-efficient water heater will help you spend less money and give your home hot water when you need it most. Water heaters will have different heater efficiency ratings, but how do you know what they mean and how they can help you choose the best heater for your home? In this blog we will break down the different water heater efficiency ratings and what they mean for their home. 

The Most Common Water Heater Types

Before we discuss water heater efficiency ratings, you should understand what type of water heater you have in your home. Different types of heaters will require different energy efficiency tests and come with different ratings. 

Storage Tank water heaters use electricity to heat and store water of a large volume on a steady basis. Higher ratings are best when shopping for these types of water heaters. 

Heat Pumps use electricity to move heat from the surrounding air to the water. These are known for their better efficiency and energy savings. 

Tankless Water Heaters heat water on-demand which means you will always have hot water when you need it. Their ratings are based on Gallons Per Minute, which shows the buyer how much hot water they can deliver. 

Energy Factor (EF)

This is the most widely used rating for water heaters no matter what type you have. The rating includes standby heat loss, cycling losses, and recovery efficiency. When you have a higher energy factor rating this means better efficiency for your home. EF ratings change on different water heater types and different heater sizes. 

Uniform Energy Factor (UEF)

Uniform Energy Factor Ratings take similar factors into account as EF ratings, heat loss, standby energy loss, and cycling loss. Non-solar water heaters can be certified by Energy Star if they have a UEF rating of less than 3.30. Energy Star has other criteria like First Hour Rating and Upper and Lower Compressor Cut-Off Temperature that go into a better UEF rating.

Energy Star Certification

The Energy Star Certifications are run by the U.S. Environmental Protection Agency which certifies what appliances are the most efficient for your home. Energy Star Certifications will usually list the annual consumption of water in kilowatt-hours (kWh). This helps buyers see how much they could spend on operating costs for a typical home. 

When a water heater meets these efficiency requirements you will have a more sustainable home, save money on energy bills, and have peace of mind about how your water heater will run. Using less energy will not only benefit the environment but will make your wallet much happier too. 

First Hour Rating (FHR)

This water heater rating is only used to measure the amount of hot water that the tank can deliver during the first hour of use. The rating is determined by looking at your heaters storage tank and analyzing the tank size, insulation, and burner efficiency. When you have a high First Hour Rating, this means you will have better hot water availability. 

Thermal Efficiency

A thermal rating refers to how effectively a water heater converts the energy into fuel and then into hot water. These water heater efficiency ratings are usually attached to gas-powered heaters and are represented by a percentage. For example, if a water heater has a thermal efficiency rating of 84%, that means that it converts 84% of the energy it produces into hot water, while the other 16% is essentially wasted fuel.  

Can I Increase My Water Heater Efficiency Ratings?

If you are unsatisfied with the ratings your water heater has produced, there are some things you can do to make it more efficient. Some options to help increase your ratings include:

• Insulate the water heater and the connecting pipes
• Turn down the temperature of the water heater
• Set a timer on your water heater so it only runs at high-use times
• Get regular maintenance from a plumber
• Replace your water heater with a more energy-efficient model
