Best Gas Tankless Water Heater for Your Home

A gas water heater can be a good alternative to an electric powered water heater and there are a lot of reasons to go with propane and natural gas. A gas water heater works by igniting the gas and then pushing the hot air upwards to heat the water. The waste product that is given off by the burning process is then vented outside of the home. Hence, heating water is faster compared to electric heating.

Gas Water Heater vs Electric Water Heater

So, how does gas water heater stack up against the other types of water heaters that are on the market today? There are several factors to consider. We’re listing the gas water heater and electric water heater.

A standard gas water heater is one with a storage tank that keeps the hot water stored so that anyone who runs a faucet can have near-immediate access to it. However, that also means that you incur a great deal of energy expense to keep that tank full.

In fact, the Department of Energy lists water heaters as the biggest utility expense in U.S. households. The tankless water heater only heats up water when you need it and at nearly the same speed as from the storage tank. So, this model is much more cost-effective in the long run, but they are expensive to have installed.

As far as the comparison goes, gas water heaters are definitely less expensive to run than electric water heaters. In fact, that is the number one reason that people switch to the gas water heaters. If you choose the heat-on-demand model, or the tankless water heater, you can actually save up to 50% of your normal water heating costs.

The gas tankless water heater also eliminates the need to wait for hot water. With electric water heaters that have a storage tank, if you empty the hot water out of the tank you are out of luck until it fill up again. Gas water heaters also last longer and you get cleaner water when you use them.

How to Choose a Gas Tankless Water Heater

There are a few things that you need to look at when you are choosing a gas tankless water heater. The first thing that you want to look for is how long the water heater is going to last. The longevity of the water heater is an important factor to consider and right alongside of that is the efficiency of the water heater. Looking its Energy Factor beforehand should be considered. The higher the EF, the more efficient the water heater. You obviously want to save money by having one that lasts, but you also want it to be as efficient as possible.

Next, you want to try to decide what your requirements are. There are two choices for gas water heater, propane or natural gas. If either fuel is available in your area, then choose that fuel. The cost of these fuels will vary on every company.

The flow rate and BTU’s are also important factors that you should be kept in mind. Depending how you many gallons of hot water you need in your household, choose the water heater with enough flow rate (gallons per minute) to supply you enough hot water.

Finally, you need to do some comparisons and look at the gas water heater reviews to see how people are rating the units that they have. Then, you’ll have to decide if you want to install it yourself or hire someone to do it.

Benefits of the Tankless Gas Water Heater

As mentioned when doing the comparisons, gas tankless water heaters have many benefits. You don’t have to wait for hot water to come and you save money because gas is cheaper to run. When there is an unexpected power outage, gas water heater is not affected. Also, gas water heaters make for cleaner hot water.
