Understanding Tankless Water Heaters

What is a tankless water heater

A tankless water heater, as the name suggests, is a type of water heater that doesn’t require a storage tank. Instead, it heats water directly as it flows through the unit. This kind of system is also often referred to as an ‘on-demand’ water heater because it provides warm water precisely when you need it.

How does a tankless water heater work

Tankless water heaters work by heating water directly without the use of a storage tank. When a hot water tap is turned on, cold water travels through a pipe into the unit. Either a gas burner or an electric element heats the water. As a result, tankless water heaters deliver a constant supply of hot water. There’s no need to wait for a storage tank to fill up with enough hot water.

Benefits of a tankless water heater

Tankless water heaters have a significant number of benefits. Firstly, they are more energy-efficient because they only heat water when it’s needed, reducing power usage. Secondly, because they don’t require a storage tank, they take up less space in your home. They also lower the risk of water damage due to tank leaks. Lastly, they often have a longer lifespan than conventional water heaters, making them a good long-term investment.

Feasibility of DIY Installation

Skills needed for DIY installation

If you’re considering a DIY installation of a tankless water heater, it’s important to have some basic skills and understanding. You should be comfortable with basic plumbing and electrical work.
