Tankless Water Heater

What is tankless water heater:

What is tankless water heater Tankless water heaters, also known as demand type or instantaneous water heaters, provide hot water only as it is needed. They don't produce the standby energy losses associated with storage water heaters, which can save you money.

How They Work:

How They Work Tankless water heaters heat 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. You don't need to wait for a storage tank to fill up with enough hot water. However, a tankless water heater's output limits the flow rate.

Advantages of Tankless Water Heater:

Advantages of Tankless Water Heater Most tankless units come with a federal tax rebate of $300 . They never run out of hot water . They last five to 10 years longer than tank heaters . They're more efficient with no standby heat loss . They take up less space and can even be installed on walls or outdoors with an anti-freeze kit . Smaller units can be installed under cabinets or in a closet, closer to the point of use . They only need enough power to heat the amount of water necessary at any given moment . You can shave as much as 20 percent from your water heating bill . Electric models don't produce greenhouse gases . Most units are operated by remote control and have up to four separate settings available . There's no possibility of flooding due to a ruptured tank.

Disadvantages of of Tankless Water Heater:

Disadvantages of of Tankless Water Heater They cost up to three times as much as a tank water heater . Your hot water output is split among all your household fixtures . You may need to add a larger natural gas line to supply the unit with enough fuel . Venting gas and propane units requires expensive stainless steel tubing . Electric models may require an additional circuit . Gas-powered units produce greenhouse gases . Gas units require the additional expense of an annual servicing . Electric models require a lot of energy . They need a minimum flow rate of .5 GPM in order to activate the heat exchanger . Lag time can require you to run your water in order to get to the hot water, increasing water waste.
