Best Gas Water Heaters with Reviews

Takagi T-KJr2-IN-NG Indoor Tankless Heater Review

I have one word for this water heater: efficient.

The Takagi Tankless Water Heater is Energy Star certified, takes up less space than a traditional tank heater, and is perfectly suited to handling the needs of a 2-4 person household.

The regulating system gives you lots of control over your water temperature.

And this Takagi model even includes a remote for you for easier control.

The installation needs to be done correctly, as is the case with any major home improvement project.

But the savings on energy afterward are enormous.

This model functions beautifully and is a worthwhile investment in your home.

Rheem RTG-64XLN Outdoor Tankless Natural Gas Review

The Rheem Outdoor Tankless Heater is fast, reliable, and energy efficient.

The main advantage of this system is its speed: you get hot water in seconds.

And there are no drops to cold water in the middle.

The other advantage is that there is no venting required, since it is mounted outside.

This makes installation easier, and saves you space inside the house.

You can wire the remote control panel into the house, saving you trips outside to adjust settings.

The model is also freeze-resistant up to -30°F.

So I have no worries about the heater being outside.

Eccotemp L5 Portable Tankless Water Heater Review

The L5 is in a class all its own.

And I have yet to find another portable water heater that works as reliably and quickly as this one.

Set-up is a breeze, water heats up almost instantly when it’s turned on.

And the whole unit is relatively low-fuss.

It can be hooked up to a standard garden hose.

And it is truly a worthwhile buy whether you are a frequent outdoor adventurist, or simply live in an area where electricity outages are a concern.

The included shower head and user-friendly controls on the front of the heater are definitely nice features, too.

Rinnai RUC98iN Ultra Series Natural Gas Tankless Review

The Rinnai RUC98iN is the ultimate water heater in terms of energy efficiency, space efficiency, and high-volume use.

While there are other tankless heaters out there, this one is the most efficient and has the highest output capacity for its price.

That makes it perfect for a larger household that still wants to be environmentally conscious.

Although switching to a tankless might be a bit daunting at first, this is the model that will make it worth your while.

I would say it works better than a tank heater in terms of how fast you get hot water.

And it costs a lot less in energy.

Sounds great, doesn’t it?

Marey Power Portable Propane Gas Tankless Review

This little water heater is ideal for camping, or to have as a backup in case of an emergency.

Weighing only 12 lbs and adaptable to connect to a garden hose or an RV.

This Marey’s Portable Water Heater really can go just about anywhere.

The safety features mean you don’t have to worry about your kids’ safety using it to take showers while camping.

And the adjustable controls allow you to ensure that the water is just the way you like it.

This model heats up water quickly and constantly, giving you hot water when you need it.

How to Buy Gas Water Heaters the Right Way

Gas is one of the most affordable as well as efficient heating sources currently available.

Knowing this it’s no surprise many choose gas heaters over electric types, especially with the wide range of gas variant heaters that are constantly flooding the market.

If you really want to save cash this coming winter and cut back on your electricity bills then I think it’s time you considered a gas heating solution that is affordable and long-lasting.

Read on to find out what to look for in a gas water heater so you can make the best investment possible.

Do you choose natural gas or propane?

There are 2 types of gas fuel available that power the many gas heating units available on the market.

Natural gas is considered to be considerably cheaper than propane and burns at a slower pace meaning you get more heat for your money.

Propane gas is still worth considering for smaller areas in the home or for short term use.

With either type you must insure you offer yourself the best protection from carbon monoxide poisoning, a concern that comes with all gas heaters that are used in the home.

Natural gas heaters are most popular in the US because gas is cheaper for heating water than electricity, propane, and solar energy.

Also, most cities and towns have the gas conveniently piped throughout.

Some homes are equipped for electric or propane and do not have a natural gas outlet available.

If this is the case and you have gas stove it may be a good idea to extend the gas line to your water heater.

Tank size & rate of flow

A properly sized heater is necessary in order to meet a household’s need for hot water efficiently.

A heater that is too small will not provide enough hot water, and who wants to take a cold shower in the morning?

If your heater is too big, then you will overpay to operate it.

So, how do you determine what size gas water heater your home needs?

Calculators are available online to determine your typical water-use and the water-use of your appliances and the amount of hot water the gas water heater can produce in an hour.

A larger tank capacity doesn’t necessarily mean it’s the best out there, the same goes for flow rate.

Look for a system that fits your requirements rather than spending all the money available in your wallet!

Larger tanks take considerably longer to heat up the water in the tanks meaning flow rate is considerably low.

Strike a balance, find a system that is not to large or too small so the flow rate is just perfect.

Remember, you want to save money, not spend it!

Safety and ease of use

Many of the heater systems on the market come with a range of features to offer you the best protection possible.

It’s worth paying that little bit more as no price can be put on you and your family’s health.

Features to look out for include automatic valve shutoff when carbon monoxide levels are high, pilot disengages to prevent flammable vapors from being ignited and more.

Take your time when buying your new heating system, I recommend speaking to a specialist or visiting your local store for more on the features currently available and what they can do for you.

For some of the best deals around why not check out one of many online stores on the net, you can make some great saving on gas heater water systems.

Energy efficiency

This is based on the heater itself.

Typically the most energy efficient models are the most expensive.

Don’t let the high price of the unit fool you into thinking you are wasting your money.

In fact, an expensive gas water heater that is highly energy efficient will pay for itself and save you money on your monthly bills by cutting down on energy costs.


It is important to estimate a heater’s annual operating costs so that you can make an informed decision about which one to purchase.

Maintenance costs and installation add to the cost of purchasing a heater and should be considered as well.

Taking into account the size of your home, and the energy efficiency and fuel type of the unit, should help you choose the heater that is right for you.

When selecting the best gas water heater for your home, it is important to consider these points.

Overlooking any one of them could cost you money.

Gas water heaters are a modern convenience, but choosing the wrong one could be a major inconvenience on your monthly energy bill.
