Jay and I have been thinking of getting a tankless water heater that runs on propane. There are many benefits of a tankless water heater. Tankless water heaters are small compact units that provide hot water as it is needed. Hot water is not stored like it is in a tank type water heater. A standard tank water heater keeps 40-80 gallons of water heated to a temperature of at least 120 degrees every minute of every day whether your home or not. Because tankless water heaters do not store hot water, they are much more energy efficient and can reduce water heating bills by 10-20 percent. A conventional tank heater is constantly heating and reheating water because heat loss occurs because the water is just sitting in the tank. Tankless water heaters eliminate this heat loss which reduces energy consumption by 20-30 %. According to the Department of Energy, the he average household spends between 14-25 percent of its energy budget on heating water. Tankless water heaters last twice as long as traditional water heaters since they are less likely to corrode since they do not store water. Tankless water heaters also are less likely to leak also since they are not under constant pressure. Tankless water heaters are more expensive than traditional water heaters but they provide significant energy savings and they last longer so they will pay for themselves in a short amount of time. The energy to power tank water heaters come from fossil fuels such as coal, oil, or natural gas which are harmful to the environment. By reducing the amount of power used to heat water, the amount of fossil fuels burned will be less which will reduce greenhouse gas emissions. If all Americans would replace their tank hot water heaters with a tankless water heater, almost 300 million gallons of fuel oil or over 160 million gallons of propane, or over 6 billion kilowatt hours of electricity would be saved a year.
