Understanding Tankless Water Heaters
What Are Tankless Water Heaters? Tankless water heaters, also known as on-demand or instantaneous water heaters, are a modern alternative to traditional tank-style water heaters. These compact units are designed to heat water as it flows through them, providing hot water only when needed. Unlike tank-style water heaters, tankless models do not store water, which can result in significant energy savings and a continuous supply of hot water.
How Do They Work? The operation of tankless water heaters is relatively simple. When you turn on a hot water tap or an appliance requires hot water, cold water enters the unit from the main water supply. Inside the heater, powerful heating elements or a gas burner heat the water to the desired temperature in a matter of seconds. This process ensures that you have a constant flow of hot water without the need for a storage tank.
Venting Options for Tankless Water Heaters
Importance of Proper Venting Proper venting is crucial when it comes to tankless water heaters. It ensures the safe removal of combustion byproducts, such as carbon monoxide, from the unit and your living space. Choosing the right venting material and installation method is essential to maintain a safe and efficient operation.
Common Venting Materials Several materials can be used for venting tankless water heaters. Common options include stainless steel, aluminum, and PVC. Each material has its advantages and considerations, making it important to choose the one that best suits your specific installation and local code requirements.
