Tankless, or need, water heaters have long been fixtures in Europe and Japan. With the new push in the United States toward greater energy efficiency, these water heaters are becoming more popular. Instead of always using energy to warm a large tank of water as conventional water heaters do, these tankless heat water on demand and offer an endless supply of hot water to the home. Like most things, there are some issues with this technology, but with a bit of research, the tankless water heater it’s a valuable choice for the household.
Most of us are familiar with the shortcomings of traditional water heaters. They use more energy in a home than anything except heat and air conditioning. In most houses, you must limit the amount of hot water-using appliances which are running at any given time. The horror of having someone turn on the dishwasher when you’re in the shower is a situation that is familiar to many. Tankless water heaters fix many, but not all, of these problems. Gas models have a higher flow rate, delivering more hot water at one time, but cost more in energy to keep the pilot light lit. Both gas and electric models run the same manner. Cold water is delivered through a pipe to the small, wall-mounted unit. A heating element heats the hot water as it flows through at a rate of 2-5 gallons per minute. Because there’s no tank to empty, the amount of hot water flowing through the tap is infinite. Putting the device closer to the point of use can increase both the efficiency and speed the hot water is delivered.
Though they generally cost 2 1/2 times more than a conventional hot water heater, this price can usually be made up in energy savings within a couple of years. The average tankless user saves 30-45% in energy use every year. Often a tax credit is available for purchasing a tankless water heater, which may help offset the price tag. Due to the calculations needed to ascertain which model is best for your use as well as the difficulties involved in installation, this is not generally a do-it-yourself project. It’s very important to employ a professional plumber or contractor to install your tankless heater.
Since they’re small, tankless heaters save space both in the home and in the landfills when their useful life is over. They can be mounted either inside or outside the house and because the gas versions are sealed, they have no open flame. This versatility has a price. Smaller units often cannot offer simultaneous use in larger houses. Often, another unit is installed that is dedicated to all those appliances which use the most hot water, such as dishwashers and washing machines. It can also take longer for the hot water to reach the tap, which may result in water waste. It’s possible to speed this process using different versions or installing a pump to aid the water as it travels. Companies that sell tankless water heaters can help you calculate your use and put in the right sized unit for your home.
It’s up to the individual homeowner to determine whether or not a tankless water heater – or two – is the correct option for their dwelling. If energy savings is a long-term target, the first costs and minor problems involved in installing a tankless heater will probably be outweighed by the impressive decrease in energy required to operate these water heaters.
