Purchasing a water heater for your home, or replacing an existing one can be expensive, however it may help you save money in the long run by finding the best hot water heater for your home.

It has been determined by the U.S. Department of Energy that 14-18% of the home’s utility expenses comes from water heating. That means that the average home is spending about $400-600 on water heating per year.

While the most recent regulations on energy efficiency were updated last year via the National Appliance Energy Conservation Act (NAECA), raising the minimum energy efficiency of all water heaters, there are still several options to choose from.

Depending on your home’s size and water consumption, you can save money on energy consumption by choosing between options such as storage vs. tankless, and gas vs. electric. Presented here is a complete overview of the best water heaters, including different types, a water heater comparison, and reviews of the top rated water heaters.

Types of Water Heaters

Tankless Water Heaters

Eccotemp L5 Portable Tankless Water Heater and Outdoor Shower

Tankless water heaters, or instant water heaters, are different from traditional water heaters in their ability to generate hot water on demand, rather than relying on stored, continuously heated water.

Tankless water heaters can be either electric or gas, which may determine installation costs, efficiency and capability. Due to the on-demand nature of the product, the performance of a tankless water heater can be affected by warm versus cold climates.

Tankless water heaters are going to be a bit more expensive than traditional storage water heaters, but can be up to 34% more efficient depending on location and demand. They are also much more compact and therefore more convenient to install than a traditional storage tank.

Gas Water Heaters

Rheem RTGH-95DVLN 9.5 GPM Indoor Direct Vent Tankless Natural Gas Water Heater

Gas water heaters are generally more energy efficient than electric for two reasons: one, gas is going to be cheaper than electricity and two, gas hot water heaters work faster than electric models.

Because they work faster, they provide more available hot water during high usage times. For those looking into gas water heaters, there is the option for both storage and tankless gas water heaters.

However, one of the main complications in purchasing a gas water heater can be the access to a gas line. Natural gas water heaters need both a gas line and space for proper venting of the combustion that occurs.

Electric Water Heaters

Stiebel Eltron Tempra 24 Plus Electric Tankless Whole House Water Heater

Most electric water heaters are going to be less energy efficient than gas due to the cost difference in natural gas versus electricity usage. Electric water heaters utilize one or two heating devices which extend into the water.

Buyers have the option of either storage water heaters or tankless water heater models. Many electric water heaters contain a mechanism called dry fire protection, which prevents the upper heating element from burning out when it is not surrounded by water.

Electric water heaters have become much more eco-friendly in the past couple years. These models, while more expensive to purchase, will cut down on energy consumption over time.

Propane Water Heaters

Rheem RTG-64XLP 6.4 GPM Low NOx Outdoor Tankless Propane Water Heater

Propane water heaters are quite similar to natural gas heaters, however they use liquid propane, or LP, as the fuel source as opposed to natural gas.

In this case, when purchasing a propane water heater, you must also factor in propane storage and regular fuel delivery.

An electric or natural gas heater will usually share the same heating source that provides heat for your home, while a propane water heater uses an external heating source.

Buyer's Guide

There are very few of us out there who enjoy a cold shower, therefore, buying the right hot water heater is quite an important decision-especially for those living in colder, northern climates. However, deciding which water heater to choose may require a bit more consideration.

One of the newest considerations is going to be whether or not to buy a conventional storage tank water heater or a tankless water heater.

Most households in the United States right now rely on electric storage tank water heaters to provide hot water for their home. With new technology breakthroughs though, tankless hot water heaters are becoming more and more popular. To choose between tank and tankless, it is important to determine what your household needs are.

Tankless water heaters are great because they provide on-demand hot water. They are space-saving, easy to install, and usually last 10 to 15 years longer than the average storage tank. However, they are more expensive to purchase and may prove inconsistent if you have a large family household where multiple use scenarios regularly occur.

In addition, if you live in a very cold climate where temperature rise is consistently an issue, it may be better to invest in a storage tank water heater.

Finally, you will also have to choose between electric, natural gas, and propane. This decision may merely be based on which energy source heats your home. Natural gas will need a gas line, and will more than likely require venting to defer the fumes.

Therefore, if your home is already heated electrically, this may be the best option. Propane requires storage for liquid propane (LP) and may need regular delivery, and therefore may be more inconvenient if other energy sources are available.


Buying a new water heater can drastically change the quality of your household water usage from comfort, to reliability, and especially, cost efficiency. There are many choices out there and it is important to choose the right one for your household.

This complete buyer’s guide sought to help make this decision a little easier by going over different types of water heaters, reviewing some of the most popular products out there, and looking at the best hot water heater brands.
