Being able to take a hot shower whenever you like is one of the perks of modern society, along with free wifi, and processed food full of gluten. However, finding the right gas water heater to provide you with that hot water any time of the day is quite hard, especially if you don’t know exactly what to choose. So, after going through loads of online reviews ourselves, we have reached the conclusion that one of the best gas water heaters in the industry right now is the Takagi T-KJr2-IN-NG because it burns at approximately 140,000 BTU, it requires a 4-inch stainless steel venting, and comes with inlet and outlet thermistors for providing a constant water temperature.

Buying guide


If you’re in the market for the best gas water heater, you need to take into consideration certain aspects to make sure you made the right purchase choice. So go through our comprehensive shopping guide and find out everything you need to know about the best water heater on gas available for sale right away.

Why get a gas water heater in the first place?

First of all, we would like to congratulate you on your choice. There are several types of water heaters on the market, including those fueled by gas and regular electricity. However,  gas-fueled boilers are a greater investment because they cost less and will provide the right amount of hot water without increasing your monthly electricity costs.

Moreover, gas heaters are mainly suitable for larger families, especially if you still want to have enough money to pay the other bills, and still being able to survive through the month.

And, compared to the electric models, water heaters fueled by gas are more reliable in the long term, and can also be stored in unheated rooms.


The size of your household

A good gas water heater will not only provide you with hot water, but will also take care of all your household needs, and make sure you always get to finish your chores without running out of water during an important moment. Thus, the first thing you need to take into account when looking for the right gas boiler is the size of your household.

Obviously, some gas-based burners are specifically designed to meet the needs of large families with an increased water consumption, while others are perfect for smaller apartments with one or two inhabitants.

So think wisely of your family needs – how many times per day is the shower used, how often do you cook, shave or perform other activities that require the use of hot water, and then decide which type of water heater is the perfect one for you.


Think about the climate you live in

Another thing to take into consideration is the actual place you live in. Do you live in a house that is fully insulated? Are winters warm or usually cold and full of snow? If you live in a state with low temperatures and cold winters, you might want to invest in a unit that is more powerful and will be able to maintain your water hot regardless of the temperatures outside.

Similarly, if your house is fully insulated and you keep your boiler inside too, there is no need to opt for more powerful items, especially if there aren’t too many family members either.


Tank or tankless?

Last but not least, you should also consider the type of your gas water heater. The regular models come with attached water tanks that can store the water and maintain it hot when you’re not using it. The downside is that once the tank is empty, you will have to wait up to 40-45 minutes until you can take a shower and enjoy your hot water again.

Tankless designs are often more expensive and harder to mount, but they are also more convenient in the long term as they will only provide hot water when needed, and won’t use too much fuel to heat the entire tank of water at once. This means lower monthly gas bills and a more convenient use of household water.

If you’re not really sure which item is the best one for you, we suggest reading some reviews of gas water heaters online and see what other buyers have to say about certain products.
