What is a Tankless Water Heater?

More info on tankless water heaters 

What is a Tankless Water Heater?
Tankless Water Heaters, also called Instantaneous or Demand Water Heaters, provide hot water only as it is needed. Traditional storage water heaters produce standby energy losses that cost you money. We do not leave our homes heated while vacationing. We only heat our homes when there is a demand for heat. In the same way, a Tankless Water Heater is used only when there is a demand for hot water.
How do Tankless Water Heaters work?
Tankless Water Heaters heat water directly without the use of a storage tank. Therefore, they avoid the standby heat losses associated with storage water heaters. When a hot water tap is turned on, cold water travels through a pipe into the unit. In an electric Tankless Water Heater an electric element heats the water. In a gas-fired Tankless Water Heater a gas burner 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. Typically, Tankless Water Heaters provide hot water at a rate of 2 – 5 gallons (7.6 – 15.2 liters) per minute. Typically, gas-fired Tankless Water Heaters will produce higher flow rates than electric Tankless Water Heaters. Some smaller Tankless Water Heaters, however, cannot supply enough hot water for simultaneous, multiple uses in large households. For example, taking a shower and running the dishwasher at the same time can stretch a Tankless Water Heater to its limit. To overcome this problem, you can install a “whole house” type Tankless Water Heater or install two or more Tankless Water Heaters, connected in parallel for simultaneous demands of hot water. You can also install separate Tankless Water Heaters for appliances-such as a clothes washer or dishwater-that use a lot of hot water in your home.

Other applications for Tankless Water Heaters include the following:
Remote BBQ or outdoor sink
Poolhouse or pool shower
Remote bathrooms or hot tubs
To serve as a booster, eliminating long pipe runs, for solar water heating systems, dishwashers and sanitation.

For homes that use 41 gallons or less of hot water daily, Tankless Water Heaters can be 24% – 34% more energy efficient than conventional storage tank water heaters. They can be 8% – 14% more energy efficient for homes that use a lot of hot water, around 86 gallons per day. You can achieve an even greater energy savings of 27% – 50% if you install a Tankless Water Heater at each hot water outlet.
Selecting a Tankless Water Heater
Before buying a Tankless Water Heater, consider the following:
Fuel Type
Location, Size and Demand
Application
1. Fuel Type

The first thing that you’ll need to decide when selecting a Tankless Water Heater is the fuel type. You will need to select between an Electric Tankless Water Heater (like Eemax Tankless Water Heaters or Stiebel Eltron Tankless Water Heaters) or a Gas-Fired Tankless Water Heater (like Rheem Tankless Water Heaters).

New Years Resolution, Go Green

You may have a New Year’s resolution to get fit or stop smoking, but if your resolution is to go green this year, one Springfield couple makes a great example. Many of us recycle, but Rick Scarlett and Gloria Johnson have done much more to reduce their energy use, shrink their carbon footprint, or simply go green in the past year. “I’m amazed at what we’ve done in a year,” says Gloria Johnson.

Over the past year, Scarlet and Johnson have gone green, and they think it will save them green in the long run. “The way the economy is, you’re not sure if you’re going to make any money, so we’ve decided it’s better to lower your outgo instead of raise your income, so that’s kind of the goal we’re working toward,” says Scarlet.

They own an electric vehicle for trips under forty miles, charging it with only five dollars a month. “It may not be a perfect technology right now, but somebody’s gotta be the first on to do it,” says Johnson.

They drive a Toyota Prius for longer trips. To cut down on trips to the grocery store, they’re growing plenty of fruits and vegetables right in their own yard. “We’re just going to redo it completely into a little farm back there,” says Scarlet.

They use rain barrels to save water, and speaking of water, the strange looking thing on their roof is a solar water heater. “The gage shows the temperature in the solar water heater on the roof, and it’s in Centigrade,” says Scarlet. For cloudy winter days, there’s a backup in the basement. “It comes back down to the tankless down here, and it runs through the tankless, and the tankless bumps it up to whatever temperature you have it set for- 115,” Scarlet says.

They’re also installing chili pepper pumps that eliminate that waiting for the water to turn warm. “You don’t run a bunch of cold water down your sink,” Scarlet says.

The couple will also soon get much of their electricity from the sun. “During the winter, it’ll probably be 50% of our power, and during the summer, it’ll do really well- probably take care of most of our needs,” Scarlet says.

They’re happy to be helping the environment. “I just feel like I want to do what I can,” Johnson says.

Plus, they’re cutting their costs for the future. “I think down the road, it’s gonna pay off really well,” says Scarlet.

They also have a dual-flush toilet with a smaller flush and a stronger one, and they’ve ordered a SunFrost refrigerator that is supposed to use only 20% of the energy of a regular fridge.

They also have double-pane windows, and are putting extra insulation in their 90 year old house to increase its efficiency.

Of course, most of us won’t be able to do it all, but Rick and Gloria suggest going green one piece at a time. One simple step is to unplug or use power strips to turn off things like microwaves or TV equipment off when they’re not in use to prevent the use of phantom electricity.
