What is a tankless water heater and how does it work?
A tankless water heater is a modern alternative to traditional, tank-based water heaters. As the name suggests, it does not rely on a storage tank to heat and store water. Instead, it quickly heats the water as it passes through the unit using high-powered burners or electric heating elements. When you turn on a hot water faucet in your home, cold water enters the tankless water heater through an inlet pipe. Inside the unit, the cold water flows over the heating elements or burners, which rapidly heat the water to the desired temperature. The heated water then exits the unit and travels to the faucet, providing you with instant hot water on demand. The main advantage of a tankless water heater is its energy efficiency. Unlike traditional water heaters, which constantly heat and store water, tankless models only heat water as needed, resulting in significant energy savings. Additionally, because there is no storage tank, the risk of leaks and water damage is greatly reduced.
What is a condensing tankless water heater?
A condensing tankless water heater is a type of water heater that utilizes advanced technology to maximize energy efficiency. Unlike traditional tankless water heaters, which exhaust hot gases through a vent, condensing tankless water heaters have a secondary heat exchanger that extracts additional heat from the exhaust gases. This process not only increases the unit's efficiency but also lowers its emissions. As a result, condensing tankless water heaters are able to provide hot water on-demand while using less energy and reducing carbon footprints.
Differences between condensing and non condensing tankless water heaters
