Things To Consider When Switching To A Tankless Water Heater

If you're thinking about switching to a tankless water heater, there are several factors to consider. This decision could lead to long-term savings, increased space, and endless hot water, but it’s important to understand the specifics before making the change.

In this blog, we will walk you through everything you should know to make an informed decision to switch from a tank to a tankless water heater.

How Do Tankless Water Heaters Work?

Tankless water heaters heat water only when it is required. Unlike traditional water heaters, which store a large volume of hot water and maintain it at a constant temperature, tankless models heat water instantly as it passes through the unit.

When you open the faucet for hot water, cold water enters the unit, which then uses either gas or electricity to warm the water before it reaches your tap. This process eliminates the need for a bulky storage tank and saves space while offering hot water on demand.

Energy Efficiency of Tankless Water Heaters

One of the main reasons people consider switching to a tankless water heater is the energy savings. Traditional water heaters continuously heat water in a large tank, which wastes energy even when you are not using hot water.

Tankless water heaters, however, only heat water when needed, avoiding standby heat loss. This means you can save on your energy bills over time, especially if your household uses a relatively low amount of hot water daily.

However, it's important to remember that if you have a larger family or need hot water for multiple appliances at once, your energy savings may not be as significant. When asking yourself: Should I switch to a tankless water heater? It is necessary to consider your home's specific needs before making the decision.

Consider the Installation Process

Switching from a tank to a tankless water heater is not as simple as swapping out an old unit for a new one. While traditional tank water heaters can be installed in many areas of your home, tankless units often require more space planning.

A tankless water heater may need a dedicated power source, such as a gas line or additional electrical work for electric models. Some installations also require the replacement of old piping or upgrades to your water system to meet the new unit's requirements.

Installation costs can vary depending on the complexity of the job and whether any extra work is needed. The average cost of installation can range from $600 to $2,500, depending on factors like location and the type of unit being installed. It's always a good idea to consult with a professional plumber or installer to assess the scope of the installation and provide an accurate estimate.

Choosing Between Gas or Electric Models

Another important consideration when switching to a tankless water heater is deciding between gas and electric models. Both types have their advantages and drawbacks.

Gas models are typically more powerful and can supply hot water to larger homes or for multiple fixtures running at once. If your home already has a gas line and venting system, a gas-powered tankless water heater might be the best choice.

However, gas units require proper ventilation to prevent dangerous carbon monoxide buildup, and installation may involve additional costs for venting.

Electric tankless water heaters are easier to install, especially if you already have the necessary electrical infrastructure in place. They are typically less expensive than gas models upfront and do not require venting. However, electric units may not be as efficient for larger households with higher hot water demands. You'll need to assess your home's usage to determine which type suits your needs best.

Sizing Your Tankless Water Heater

Proper sizing is one of the most important factors when switching to a tankless water heater. If the unit is too small, it won't be able to meet your household's hot water demands, and if it's too large, you could end up wasting energy.

To size a tankless water heater correctly, you need to consider the flow rate of water required for your household's daily activities. This includes the number of showers, sinks, and appliances that use hot water at the same time.

Cost Considerations and Long-Term Savings

Tankless water heaters typically cost more upfront than traditional tank water heaters. However, they can offer long-term savings. The typical cost of a tankless water heater ranges from $500 to $2,200, depending on whether you choose an electric or gas model and the size of the unit.

Keep in mind that the installation process may also be more expensive, especially if any additional plumbing or electrical work is required.

The U.S. Department of Energy estimates that a household can save between 24% and 34% on energy costs by switching to a tankless model, depending on usage. Over the life of the unit, these savings can offset the higher purchase price.

The Impact on Water Flow and Usage

Another consideration when switching to a tankless water heater is how it will affect water flow in your home. Because tankless units heat water on demand, their performance depends on the water flow rate. If you have a large household or often run multiple appliances simultaneously, the water flow may decrease, particularly if the tankless unit isn’t large enough to meet the demand.

Longevity and Maintenance of Tankless Water Heaters

Like all home appliances, tankless water heaters require regular maintenance to perform optimally. While they don’t require as much maintenance as traditional units, you should clean the unit periodically to remove mineral buildup, especially in areas with hard water. If the unit is powered by gas, you should also have it inspected regularly for gas leaks and ensure the ventilation system is working properly.

Should You Switch to a Tankless Water Heater?

Before deciding on switching to a tankless water heater, carefully consider your household’s water needs, budget, and long-term goals. While tankless systems offer benefits like space savings, energy efficiency, and endless hot water, they may not be the right choice for everyone.

If you live in a smaller home with low water usage, a tankless system might be a great option. However, larger homes or households with high hot water demands may require more planning and a larger upfront investment.
