If you are in the market for an on-demand water heater there are some things you should know before making the big purchase. It is important to make sure this kind of heater is right for you and your home. An on-demand water heater is usually referred to as a tankless water heater; basically, a heater without the tank. They only work when the water flows through. If you already had a water heater with a tank it is going to be a slightly different change. The main difference will be the on-demand feature. However, some homes just aren’t suitable for one. Learn the positives and negatives of a tankless water heater, and if it is right for you:
Benefits of On Demand Water Heaters
The obvious benefit is that you never have to wait for the hot water when you turn on the faucet. The tankless heater provides hot water immediately through an electricity or gas burner. In fact, you can expect to save a ton a money through having a tankless heater because it is using less water and power. They are 97% energy efficient, while the tank water heaters are only 60%.
Traditional water heaters reside in your basement and maintain gallons of heated water at once. For example, a tank usually holds enough water for one shower, one dishwasher run and a load of laundry simultaneously. However, once all that water is used up you have to wait for a new tank of hot water, which can take a long time. On the other hand, a tankless water heater will produce immediate hot water only when you need it. The water is heated on the spot as it passes through the heating technology installed in your pipes.
Disadvantages of Tankless Water Heaters
Although you get fast hot water immediately all day long, it can’t produce very much hot water at once. For example, you can’t have two showers running and laundry all at the same time. A traditional tank water heater holds about 80 gallons at once putting out about 8 gallons of water per minute and a tankless water heater puts out 2.5 to 5 GPM. It’s important to know not all the rates are calculated the same, as explained by this Culpeper plumber.
There is an easy solution to this disadvantage, simply install multiple tankless water heaters throughout your home. To make this more efficient for yourself, determine the size of your home and family. On the downside, tankless water heaters may be more expensive especially if you need to install multiple heaters.
How Much Do They Cost?
A gas-powered tankless water heater will generally cost $1,500 to purchase and install, which is double the price of a traditional gas tank heater. On the bright side, it is extremely energy efficient, so you will be saving money on your power bill.
The electric tankless water heater is the cheaper option. It only costs roughly $400 to be purchased and installed.
