Everything You Should Know About Tankless Water Heaters

nsplashWe are on the cusp of a national water heater shortage. Part of the reason has to do with bad weather in key states that manufacture, Texas for example. A few years ago, Texas was hit hard by a tornado that made getting furnaces difficult. We will soon see a similar scramble in our area of Union, New Jersey trying to locate the traditional 40-gallon water heaters. This past week we have installed seventeen gas water heaters in Westfield, Scotch Plains, Springfield, Teaneck, and the Watchung, New Jersey area. We recommend having your water heater serviced and checked before the summer to be safe. The alternative is a tankless water heater for those who can’t get one in time for a replacement.

The temperature of the incoming water is used to calculate how much heat the burners must produce to deliver water at designated temperature. When the demand for hot water stops, it shuts down and stops using energy. You use only what you need at the time you need it. The small size makes it appealing to apartments, condos, and town homes.
