Buying a new water heater is a significant investment, which is why you want to make sure you choose the right unit for your home. When it comes to water heaters, homeowners have a choice between a tank storage water heater and a tankless unit. These water heaters differ in terms of cost, efficiency, and longevity, and understanding these differences is crucial in making the best decision for your household needs.
What Is a Tankless Water Heater?
A tankless water heater, also known as an on-demand water heater, is a modern alternative to conventional tank water heaters. As the name suggests, these units don’t store hot water in a tank. Instead, they heat water directly as it flows through the device. When you turn on a hot water tap, cold water travels through a pipe into the unit. Either a gas burner or electric element heats the water instantly, providing a constant supply of hot water.
How Does a Tank Storage Water Heater Differ?
A traditional tank water heater, on the other hand, works differently. These units consist of an insulated tank that typically holds 30 to 80 gallons of water. The tank is constantly heated to maintain a set temperature, ensuring hot water is available when needed.
Inside the tank, there’s usually a heating element (either gas or electric) that heats the water. As hot water is used, it’s replaced by cold water entering the bottom of the tank, which is then heated. This cycle continues to maintain a steady supply of hot water.
The Pros of Tankless Water Heaters
While water heaters with storage tanks have been the standard in most homes in the US for decades, they are quickly being replaced by tankless units. Why? Well, tankless water heaters offer several advantages that make them an attractive option for many homeowners, including:
Energy Efficiency
One of the most significant benefits of tankless water heaters is their energy efficiency. Unlike tank models that continuously heat water, tankless units only heat water when it’s needed. This on-demand heating can result in significant energy savings, potentially reducing your water heating costs by up to 30%.
Longevity
Tankless water heaters generally have a longer lifespan compared to conventional water heaters. While a traditional tank might last 10-15 years, a tankless unit can often last 20 years or more with proper maintenance.
Space-Saving Design
Tankless water heaters are compact and can be mounted on a wall, freeing up valuable floor space. This can be especially beneficial in smaller homes or apartments where space is at a premium.
Endless Hot Water
With a tankless system, you’ll never run out of hot water. Whether you need to run the dishwasher, take a long shower, or fill a large bathtub, the unit will continue to heat water as long as there’s demand.
Reduced Risk of Water Damage
Since tankless units don’t store water, there’s no risk of a catastrophic leak from a rusty or damaged tank, which can cause significant water damage to your home.
The Cons of Tankless Water Heaters
While tankless water heaters offer many benefits, they also come with some drawbacks. If you’re about to make a large investment in a new unit, you must consider the cons in order to make the right decision for your household. Take a closer look at the disadvantages of tankless water heaters and weigh them against the pros:
Higher Initial Cost
The upfront cost of purchasing and installing a tankless water heater is generally higher than that of a conventional storage tank model. This can be a significant factor for homeowners on a tight budget.
Installation Complexity
Tankless water heater installation can be more complex than installing a traditional tank model. It may require upgrading your home’s electrical system or gas line, which can add to the overall cost. A professional plumber can help you determine what type of work needs to be done to install a tankless unit.
Limited Flow Rate
While tankless units provide endless hot water, they do have limitations on how much hot water they can produce at once. In households with high simultaneous hot water demand, a single tankless unit might struggle to keep up. Fortunately, in many cases, you can install more than one unit.
Which Water Heater Should You Install?
Deciding between tankless water heaters vs. storage tank water heaters depends on various factors specific to your household, including:
- Home Size and Hot Water Demand: If you have a large family with high hot water demand, a traditional tank or multiple tankless units might be more suitable.
- Budget: If you’re working with a tight budget, the lower initial cost of a storage tank water heater might be more appealing. However, if you can afford the higher upfront cost, a tankless unit could save you money on energy bills over time.
- Available Space: For homes where space is at a premium, a compact tankless unit can be an excellent space-saving solution.
- Long-Term Plans: If you plan to stay in your home for many years, the longevity and energy savings of a tankless unit could make it a worthwhile investment.
- Environmental Concerns: For those prioritizing energy efficiency and reduced environmental impact, tankless units generally have the edge.
Ultimately, the choice between a tankless water heater and a conventional storage tank model depends on your specific needs, preferences, and circumstances. Both types have their pros and cons, and what works best for one household may not be ideal for another.
