Introduction to Tankless Water Heaters
Tankless water heaters, also known as instantaneous or demand water heaters, are a modern solution for providing continuous hot water without the need for a bulky storage tank. Unlike traditional water heaters that store hot water and keep it heated around the clock, tankless water heaters heat water on demand. This means you get hot water whenever you need it, without the wait.
One of the standout benefits of tankless water heaters is their energy efficiency. Since they only heat water when you turn on the hot water tap, they can significantly reduce your energy consumption and lower your utility bills. Additionally, their compact, space-saving design makes them an excellent choice for homes with limited space. The cost of equipment, including the type of unit you choose, can impact overall installation expenses, so it’s important to consider this when planning your budget. After the unit is purchased, you also need to factor in the installation costs.
Whether you opt for a gas, electric unit, or propane model, tankless water heaters offer a range of benefits that can enhance your home’s comfort and efficiency. In the following sections, we’ll explore the different types of tankless water heaters and what you need to consider when installing one in your home.
Types of Tankless Water Heaters
When it comes to tankless water heaters, you have several options to choose from, each with its own set of advantages. Gas tankless water heaters, for instance, are powered by natural gas or propane and are known for their high flow rates and energy efficiency. These models are ideal for larger households with high hot water demands, as they can supply multiple fixtures simultaneously without a drop in performance.

Electric tankless water heaters, on the other hand, are powered by electricity and are a great option for homes without access to natural gas. They are typically easier to install and maintain, making them a convenient choice for smaller households or those looking to avoid the complexities of gas lines.
Propane tankless water heaters are similar to gas models but use propane as their fuel source. They offer the same high efficiency and performance as natural gas units, making them a versatile option for homes in areas where natural gas is not available. Gas water heaters are generally more cost-effective and remain operational even during power outages, making them a reliable choice.
Each type of tankless water heater has its unique benefits and potential drawbacks. Non condensing units, for example, have distinct installation and venting requirements that can impact overall costs compared to more efficient condensing units. Condensing tankless water heaters are more efficient than non-condensing units due to a second heat exchanger, which captures and reuses heat that would otherwise be lost. The right choice for your home will depend on your specific needs, such as the size of your household, your hot water usage patterns, and your access to different fuel sources.
Advantages of Installing a Tankless Water Heater
One reason that many people want to switch to a tankless water heater is for the endless supply of hot water. You don’t have to worry about a storage tank running out of hot water and having to wait for it to fill up and reheat again.
Understanding how much hot water a household uses daily is crucial. Tankless water heaters can meet these demands without running out, ensuring a continuous supply even when multiple appliances are used simultaneously. However, purchasing multiple units may be necessary to adequately serve different areas of a home, which can significantly influence the overall cost.
More household members can shower at the same time of day. You can complete different chores around your home back to back without ever worrying about the hot water supply. As long as you have a source of water coming into your home, your tankless water heater can heat that water on demand.
Another benefit of this is that you can save money on energy costs for heating up water. This is because a traditional tank water heater is consuming energy around the clock to maintain a supply of hot water whether you are using it or not.
Heating water all the time ultimately consumes more energy compared to a tankless model that only heats water when you need it.
