What are the Advantages of a Tankless Hot Water Heater?
What are my options to replace my old hot water heater?
A traditional hot water heater, known as a storage water heater, has a tank in which water is constantly heated, whether or not hot water is being used. A tankless hot water heater heats water only when there is a demand for it. A heat pump water heater does not generate heat directly but uses electricity to move heat from one place to another. An indirect water heater uses heat from the main furnace or boiler used to heat the home. A solar hot water heater relies on energy from the sun.
How does a tankless hot water heater work?
Tankless hot water heaters can be electric or run on gas. When a hot water tap is turned on, cold water enters the tankless hot water heater through a pipe. An electric element or gas burner heats the water as it passes on its way to the tap or appliance that needs it.
A tankless water heater only produces hot water when there is demand for it somewhere in the home. Because water is heated as it flows through a tankless water heater, a tankless water heater can deliver a constant supply of hot water. And because you never have to wait for a storage tank to refill and reheat, you never have to wait to have hot water available. That is why they are also referred to as instant hot water heaters.
Will a tankless hot water heater keep me from running out of hot water during a long shower?
With a tankless hot water you never drain a tank of heated water. However, a typical tankless hot water heater provides hot water at a rate of 2-5 gallons per minute, with gas-fired ones producing the highest flow rates. If someone decides to run the dishwasher while your are showering you may have a problem, as the demand could exceed the rate at which a tankless hot water can provide. One solution is to install a separate tankless water heater for appliances that use a lot of hot water.
Will a tankless hot water heater save me money?
Tankless hot water heaters generally cost more than traditional hot water heaters. But they can cost less to run for several reasons. One is that there is no standby energy loss. How much you can save using a tankless water heater depends on the amount of water you typically use in your home per day. According to the U.S. Department of Energy, tankless water heaters can be 24%-34% more energy efficient than storage tank water heaters for homes that use 41 gallons or less of hot water daily. For homes that use around 86 gallons of water daily, energy efficiency can be improved by 8%-14%. If a tankless water heater is installed at each hot water outlet, you can save 27%-50%. An ENERGY STAR qualified tankless water heater could save your family $100 or more per year.
