Tankless, or need, water heaters have long been fixtures in Europe and Japan. With the new push in america toward more energy efficiency, these water heaters are gaining popularity. Instead of always using energy to heat a large tank of water as conventional water heaters do, these tankless models heat water on demand and offer an endless supply of hot water to the house. Like most things, there are some issues with this technology, but with a little research, the tankless water heater it’s a valuable option for today’s household.
Most people are familiar with the shortcomings of traditional water heaters. They use more energy in a household than anything except heat and ac. In most homes, 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 are in the shower is a scenario that is familiar to many. Tankless water heaters solve many, but not all, of these issues. Gas models have a higher flow rate, delivering more hot water at the same time, but cost more in energy to keep the pilot light lit. Both gas and electric models run the same way. Cold water is delivered through a pipe into the small, wall-mounted unit. Because there is absolutely no tank to drain, the amount of hot water flowing through the faucet is infinite. Placing the device closer to the point of use can increase the efficacy and speed the warm water is delivered.
Although they typically cost 2 1/2 times greater than a conventional hot water heater, this cost can usually be made up in energy savings within a year or two. The typical tankless user saves 30-45% in energy usage each year. Frequently a tax credit is available for the purchase of a tankless water heater, which may help offset the cost. Because of the calculations needed to ascertain which model is best for your use as well as the difficulties involved in installation, this isn’t normally a do-it-yourself project. It’s important to employ a qualified plumber or contractor to install your tankless heater.
Because they are small, tankless heaters conserve space both in the house and at the landfills when their useful life is over. They can be mounted either inside or outside the house and because the gas models are sealed, they have no open flame. This versatility comes with a price. Smaller units often can’t provide simultaneous use in larger homes. Often, a second unit is installed which is dedicated to all those appliances that 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 might lead to water waste. It is possible to accelerate this process using different versions or installing a pump to aid the water as it travels.
It’s up to the individual homeowner to decide if or not a tankless water heater – or 2 – is the correct option for their dwelling. If energy savings is a long-term goal, the initial costs and minor problems involved with installing a tankless heater will probably be outweighed by the remarkable decrease in energy needed to run these water heaters.
