How to choose the best gas water heater (buying guide)

Best Gas Water Heaters For Home Use

Capacity and size 

The first consideration should be the amount of hot water a unit can deliver and its size. To determine the amount of hot water, take a look at the hot water demand output in your family and compare it to the capacity of your desired unit.

For example, if your family spends 40 gallons of water per day, you should buy a unit that can store more than 40 gallons.

Of course, if you go tankless, this shouldn’t be a problem. But simply considering the GMP or gallons per minute would save you a lot of trouble.

Features 

Features are what you need to consider next. Here are a few features you are likely to see in a water heater.

  • Digital display: It gives you information about the temperature or the performance of the unit.
  • Anti-scale devices: This feature allows the unit to reduce mineral scale buildup inside the tank, thus lengthen its durability.
  • Brass drain valves: Go for brass drain valves rather than the plastic ones since they are more durable.

Energy Efficiency 

The energy efficiency rating tells you the amount of money you save at the end of the month. Most tankless water heaters have an efficiency rating of 0.82, which means they save you a lot of electricity or gas.

Since they have no storage tank and energy is used only when you open the tap, the energy rating is higher than other types.

Warranty 

Water heaters come with a warranty of 3 up to 15 years. Of course, your water heater is less likely to break after a few years, but just in case, you should aim for a unit with the longest warranty.

Budget 

How much you want to spend on a water heater. Not just the initial price you have to pay to buy one, but the installation and running cost. Think about it carefully.

FAQs

Top 7 Best Gas Water Heaters For Home Use

How long does a gas water heater last?

No matter how sturdy your water heater is, it will never last longer than 15 years (more or less). Of course, the answer to this question varies depending on how you take care of your unit.

If you know how to flush a water heater and do it according to the manufacturer’s recommendation, you have a few more years to enjoy. The materials to build a water heater play an important role too. A fiberglass tank water heater is likely to be more durable. Sometimes manufacturers can offer a lifetime warranty on the tank.

When should you replace a water heater?

Regular maintenance will allow your water heater to stay longer. However, if your water heater is above 10 years old or starts having leaks, you need to consider either upgrade it or replace it with a new unit.

Before the replacement or upgrading process, check whether there is an electrical problem to blame for the unit’s failure.

Can water heaters explode?

Yes, it isn’t a myth. Your water heaters can be exploded due to internal machinery failure.

A water heater explosion happens when the T&P, also known as the temperature and pressure relief valve is broken, blocked or plugged. The valve works to release pressure, stream and handle the rising temperatures.

If the valve stops working properly, the pressure will build up and eventually lead to an explosion.

Is it normal to smell gas from the water heater?

Here is a simple explanation. Natural gas has absolutely no smell, but mercaptan has been added to the gas just so it would be easier to detect when leaking. If you smell “gas,” that indicates a problem with your water heater or other gas equipment.

However, you need to make sure that what you smell is a gas odor. Water heaters are often located in places that exposure to mold and air pollutants, which can cause a weird smell in the water.

Can a homeowner install a gas water heater?

If you trust in your mechanical ability to tackle the job yourself, go for it. But remember most manufacturers will refuse to compensate any damages occur later on if they know the water heater wasn’t installed professionally.

What do you do if your water heater is leaking from the bottom?

The leaks can either come for the T&P valve or drain valve. Malfunction of either one can lead to a puddle of water or leaks at the bottom. Problems caused by the T&P valve can be serious, you should replace the valve or call a plumber to help.

Leaks can occur from the internal tank in case you use tank water heaters. The water leaks are slow and it would take you a long time to notice. Typically, this happens because of sediment buildup. If it the case, you surely need to replace the water heater.

The bottom line 

When it comes to the best gas water heater, I only entrust these 7 items for their superiority, built quality and performance. I would recommend you running through the list carefully and pick only what matches your budget and preferences.
