When it comes to investing in any large home appliance, you want the highest quality money can buy. So if your home needs some hot water upgrades, only the best gas water heater will do.
You should know that there are different kinds of water heaters available on the market. But how do you choose the best gas water heater? After all, each water heater comes with its own set of features, pros, and cons.
Before you drop big bucks on a new water heater, you need to take the time to determine your household needs and how different types of water heaters can meet them.
What You Need to Know Before Buying the Best Gas Water Heater
Shopping for a new home appliance can be intimidating. Here are some of the features you should consider before choosing the best gas water heater for your home.
You should choose a gas water heater that has the best construction possible.
Why? Because having a sturdy construction makes the appliance last for a longer period. With such models, you won't have to worry about replacing them shortly.
In fact, some options for the best gas water heater feature a corrosion-resistant interior.
Many gas water heaters have digital displays that provide information for how they work. Not only this, but the displays can also help you customize operation and examine water levels.
So, you should choose the gas water heater with the best digital display for your needs.
It’s best to choose a gas water heater that comes with an official ENERGY STAR rating. Water heaters that have the ENERGY STAR rating come with electric heat pumps, solar power, or other high-efficiency technology.
These units heat the water just like regular water heaters but with much lower energy consumption, often using up to 30 percent less energy.
Of course, the best gas water heater for you will need to come in the right size.
Often, the size of a water heater will also affect its weight. Therefore, you should buy a water heater that is the right size to fit in your home, and that won't be too heavy for its permanent location.
Prevention is better than a cure
You should choose a gas water heater that has an anti-scale feature. This technology helps prevent the buildup of sediment and minerals at the base of the tank by swirling the water.
However, the downside is that anti-scale water heaters can have much shorter lifespans than regular water heaters. So, if you want to purchase a gas water heater with an anti-scale device, ensure that it comes with a warranty of at least 12 months.
Keep yourself safe
The warranty is extremely important when it comes to purchasing a gas water heater. Most gas water heaters have a warranty period of 3 to 12 years.
However, we suggest purchasing a water heater that comes with as long of a warranty period as possible. This will help cover repairs and keep your out-of-pocket costs low.
What Type of Water Heater Is Right for You?
Depending on your preferred energy source (electricity or gas) and how much hot water you regularly use, there are many different choices when it comes to picking out a new water heater.
Storage tank water heaters feature a tank that heats as well as stores water until it's needed. Plus, they have a pressure and temperature relief valve, which opens if either reading surpasses a preset value.
Normally, natural gas models cost less to operate and consume less energy than their electric counterparts. However, it’s also important to note that gas water heaters cost more than their electric counterparts at the time of purchase.
Tankless water heaters heat the water as you use it with the help of heating coils. Unlike storage tank water heaters, they do not store water.
These water heaters are extremely energy-efficient when compared to the storage tank water heaters. However, they only deliver 3.5 gallons of hot water per minute, depending on the inlet water temperature.
Condensing is best
Condensing water heaters are ideal if you use natural gas and require an appliance with a capacity of over 55 gallons. They're also very popular because they're extremely energy-efficient.
As a matter of fact, all condensing water heaters have an energy factor of 0.94 or above. If you're keen to decrease energy waste in your house, you should definitely consider a condensing water heater.
These appliances come in many sizes, shapes, and forms. And, like conventional water heaters, some have storage tanks as well.
Heat it up
Heat pump water heaters take heat and humidity from the surrounding area and pass it to the water. What’s so great about these devices is that they consume 60 percent less energy than their electric counterparts.
The downside is that they don't operate well in extremely cold spaces. Because of this, they require an installation location that stays between 40 and 90 degrees Fahrenheit.
