The Pros and Cons of a Gas Hot Water System

It’s always good to come home after a long day of work to a hot bath. But if you have the same heater for at least a decade, then it’s high time to replace it before it starts causing all sorts of troubles.

There are two main types of water heating systems: an electrical and a gas hot water system. Each choice has its own set of pros and cons. Today, we’re specifically talking about gas hot water systems and whether it’s beneficial or not based on your needs.

What is a Gas Heater?

One big difference between gas water heating systems to electrical ones is that it requires a tank to store water.

Basically, this type of water heating system heats cold water that is available then stores it in a tank until it is needed. The cold water is heated with a heating element, which is located at the bottom of the tank. The heater itself will turn on and off as needed to maintain the heat of the water, which is indicated by the thermostat included in the system.

Homeowners could manually turn it on or off, or they can also adjust the heat based on their preference.

Should You Choose a Gas Heater?

When it comes to choosing which water heating system to go for, one way to help you decide is the type of power you already have at home.

For example, all homes already have electricity, so going for an electric water heater is easy. However, if you have a natural gas line at home, you can also choose a gas hot water system, especially since it tends to be less expensive.

Moreover, if you previously had a gas system, you can easily replace it with the same type.

The Pros of a Gas Hot Water System

Many tend to stray away from gas-type water heating systems because of the initial cost.

Compared to a tankless water heating system, you will have to spend more when you have a gas heating system at home. However, you have to remember that your monthly bill will be much bigger if you choose a tankless choice. In the long run, the initial cost you spent on a gas-type system will be compensated with a more affordable monthly utility bill.

There are different types of gas systems that offer efficiency to homeowners.

For example, one subtype is a condensing water heater, which collects and captures water vapour to reuse it in heating water.  This helps increase the system’s overall efficiency, and its operating cost is also lower. It’s also perfect if you already have a gas line at your home.

Furthermore, gas water heaters have a higher first-hour rating (FHR) and recovery rate. The former is defined as the number of gallons a heater can supply per hour, while the latter is defined as the amount of water a heater is capable of heating in a given amount of time. Both of these numbers are important and should be part of the consideration of homeowners when looking for a specific water heater.

Both the FHR and the recovery rate are listed on the unit’s description on the manufacturer’s website.

The Cons of a Gas Heater

Among the cons of a gas heater is perhaps the one reason many shy away from it: the initial cost.

As aforementioned, gas heaters are a lot more expensive to install. You’ll need a tank, plus, you’ll need a gas line if you don’t have it already. Although you can bring back what you spent with low monthly bills, the initial cost will likely dent your budget. But, if you’re just replacing a few parts of the existing gas heating system, such as the tank, you might save more.

Speaking of gas lines, another issue is that not all houses have one. However, everyone has electricity, so it makes sense to install an electric heater compared to a gas-type. And due to its use of natural gas or propane, there is an increased risk of gas leaks that could be extremely dangerous.

Furthermore, gas heaters require more maintenance, especially with the tank. If you don’t, the tank could get corroded, which would then lead to water leaks that could damage your home if you leave it to get worse.
