Tankless water heaters, also known as on-demand water heaters, are a great choice for homeowners looking to improve water heating efficiency or replace an old water heater tank. Unlike traditional water heaters that store and heat water continuously, tankless water heaters only heat water when needed. By switching to a tankless unit, you’ll not only free up valuable space, but ease up on the energy you use.  

Whether you’re in need of a water heater replacement or just looking for ways to improve efficiency around the house, we’ve put together some need-to-knows about tankless water heaters.

What is an On-Demand Water Heater?

An on-demand water heater, also known as a tankless water heater, heats water directly without the use of a storage tank. In short, cold water flows directly through a gas or electric-powered heat exchanger, providing hot water to your faucet. 

How Tankless Water Heaters Work 

When you turn on a hot water faucet in a home with a traditional water heater, you have to wait a moment for the water to warm up. That’s because the entire tank of stored water must be warmed up before making its way out of the faucet to you. With a tankless water heater, cold water from the main water supply passes directly through a heat exchanger before exiting the desired outlet. That means the water coming out of your faucet will be warmer faster.  

The Pros of Propane Tankless Water Heaters 

Propane tankless water heaters are a popular choice for many homeowners looking to upgrade their water heating systems. These units offer several advantages, such as hot water on demand, energy efficiency, and more. Here’s a quick glimpse of some additional benefits:  

• On-demand water heating improves energy efficiency by only heating what you need. 
• Tankless design eliminates heat loss and maintains a constant temperature.  
• Parts are easily replaceable, making maintenance a breeze.

And The Cons 

Much like any other appliance, there are a few drawbacks to consider before investing in a tankless propane water heater, such as higher upfront costs and potential limitations when it comes to the amount of hot water they can produce. Let's take a closer look: 

• Larger homes may require multiple units to keep up with household needs, increasing the upfront cost. 
• Some homes may require upgrades to gas lines, electrical wiring, or venting prior to installation. 
• Low gas levels can interfere with the tank’s ability to ignite and its overall performance.

How Much Propane Does a Tankless Water Heater Use? 

The average propane tankless water heater producing 40,000 BTU/hour will consume about 1.5 gallons of propane per day. However, the final numbers depend on two things: daily hot water usage, and unit efficiency. 

Generally speaking, propane tankless water heaters are efficient and unlikely to increase your propane usage drastically. However, if you have a tankless water heater that’s too small for your home, it will have to work overtime to keep up and use more propane than necessary. It’s not uncommon for homeowners with large properties to invest in more than one tankless heater to increase efficiency. Call your trusted local plumber for advice on your specific water heater needs.  

You can maximize your propane system’s efficiency by getting regular checks, performing preventative maintenance, and scheduling fills on a regular basis. 

How Much Do Tankless Water Heaters Cost? 

Brand, size, and features can all impact the price of a propane tankless water heater, but they usually run anywhere from $1,600 – $4,500 with installation.  

Should I Invest in a Propane Tankless Water Heater? 

If you’ve been dreaming of retiring your bulky water heater tank, or just want to save energy and space in your home, a propane-powered tankless water heater may make the perfect replacement. With their convenience, reliability and efficiency, you’ll wonder why you hadn’t made the switch to propane-powered appliances earlier.
