What is all the hype about
tankless (tank free) water heaters? Should you install one in your Winter Park home?
According to the Office of Energy and Renewable Energy at the U.S. Department of Energy, water heating is the third-largest expense in most homes after heating or air conditioning and operating major appliances. Energy required for hot water is approximately 14-25% of the homes expense. Many homeowners, builders and now architects are looking at ways to reduce this expense.
A standard hot water tank heats the water
resevoir 24 hours a day while a
tankless unit only activates when hot water is needed. So instead of using energy to keep a tank of water heated at all times, a
tankless system only pulls energy when the consumer wants hot water. It is estimated that you will see a 25% annual savings compared to using a 40 gallon tank.
The critical factor in purchasing a
tankless system is to make sure that it is sized correctly for your needs. Even if the system is pushed past its limits, the system will supply hot water to multiple sources simultaneously, but at a reduced flow rate. This is in contrast to a hot water tank in that once the tank is emptied, it must be refilled and reheated which is a lengthy process.
Savvy, forward green-thinking
homebuyers are going to demand this technology in their homes. Architects are being educated on the use of the
tankless systems and their benefits. The unit must be placed in a central location of the home so that the water lines will have a relatively short run. Short run water lines will improve efficiency. In large square footage homes, it is common to see several
tankless systems through out the house. Because these units have a small footprint and secondary benefit is more usable space.
In general, initial
installation is about the same cost as a traditional hot water tank system. However, on a retrofit, it is more costly to replace a hot water tank with a
tankless system.
With increasing energy prices, we are sure to see more tankless installations for hot water in Winter Park.
