tankless hot water heatersA conventional water heater constantly heats water in the tank, irrespective of whether it’s being used or not. By comparison, tankless water heaters only heat water when it’s needed. Less stored hot water means less cost, not to forget a user-friendly wall-mounted, compact design.

Here are a few things to learn about tankless hot water heaters:

  • Size Does Matter: You can get tankless water heaters in ‘room’ or ‘whole house’ sizes. Calculate how many fixtures or appliances need hot water to determine the best size for your home. For the average family, a whole-house system is usually required.
  • Fuel Type: Tankless hot water heaters are available in either gas (propane or natural) and electric models. If you prefer to go with electric, check for amperage and voltage requirements.
  • Know the Flow: If someone is showering and you want to run the dishwasher at the same time, assume a larger GPM (gallons per minute) rate will be required to meet your water needs. Also take into account water usage – a dishwasher needs less water than a shower, a bathroom needs less than a kitchen, and so on.
  • Energy Efficiency: According to the Department of Energy (Energy Efficiency and Renewable Energy website), tankless hot water heaters can be 24 – 34% more efficient than conventional tank-style versions, depending on a household’s daily demand for hot water.
