How Do Tankless Water Heaters Work? 

A tankless water heater, also called an on-demand water heater, operates by swiftly heating water as it moves through the system, eliminating the need for a storage tank. When you open a hot water faucet or start a hot water device, cold water enters the tankless water heater through an inlet pipe. Inside this unit, there's a heating mechanism, which can either be a gas burner or an electric heating element. The cold water flows over this heating element, rapidly raising its temperature to the desired hot water level. Once heated, the water exits the tankless heater and reaches your faucet or appliance, instantly providing a continuous stream of hot water. Upon turning off the hot water tap, the tankless heater ceases its heating process, resulting in energy savings since it only functions when hot water is required. This method guarantees a consistent hot water supply without waiting for a storage tank to refill and reheat.

Types of Tankless Water Heaters

Depending on your needs, three different types of tankless water heaters can be beneficial for houses. Each one has its essential role for specific kinds of systems. When you're getting a water heater put in, you can pick from the following options:


These tankless water heaters run on gas and are often used in bigger homes or buildings where hot water is used. Even if the power goes out, they're good and heat water fast. But they must be set up safely with proper ventilation and gas supply.


Propane tankless water heaters are a good choice when you can't get natural gas quickly or are not cost-effective. They're common in places where natural gas lines aren't available, like rural areas. Propane is kept in tanks and can be quickly filled in.


These are smaller and work well for smaller homes or places with little room. Electric tankless water heaters are good with energy because they only heat water when needed. They're easier to install and don't need special vents. However, they might limit how much hot water they can give you.
