On-Demand Water Heater
How Does a Tankless Water Heater (on-demand water heater) Work?
Tankless water heaters, also called instantaneous or on-demand water heaters, work to heat water immediately as it is used instead of storing a full tank of hot water at all times. The tankless water heater unit is compact and hangs on a wall, taking up less space than a regular hot water tank. When a hot-water tap is turned on anywhere in the home, cold water goes into the tankless unit where it is heated immediately by either a gas burner or electric element, then it is fed into the plumbing system and comes out hot at the tap.

What are the Benefits of a Tankless Water Heater (on-demand water heater)?
Green Choice
Traditional hot water tanks use energy constantly to keep the water stored inside hot at all times. A tankless water heater only heats water as you use it. Because a tankless heater can heat water immediately, it does not need to use energy all day every day the way that hot water tanks do, but instead only heats water when you turn on the faucet.
Saves Money
Although tankless water heaters are more expensive to buy than hot water tanks, they will save you money on your energy bill in the long run. This is because they only use energy when hot water is being used, whereas tanks use energy 24/7 in order to store water at a high temperature.
Small-Space Friendly
Many people like tankless water heaters because they take up so much less space than a hot water tank. Generally, you don’t need more than about the size of a broom closet to install your tankless water heater. This makes it a great choice for residents of apartments, condominiums, or houses that do not have a basement.
Unlimited Hot Water
Tankless water heaters give you an unlimited supply of hot water because they heat the water on demand. While conventional hot water tanks can only supply the amount of hot water that fits in the tank at one time, tankless models heat the water immediately as it is being used, so you can take as long of a shower as you want.
Longer Lasting
Tankless water heaters last longer than conventional hot water tanks. This is in part because, without having to store water, there is less likelihood of corrosion. Most tankless models also have replaceable parts, so often you can repair your water heater rather than replace the whole thing when issues arise. With regular professional maintenance, a tankless water heater should stay in good condition for around 20 years.
