Tankless hot water heaters are available in gas, electric, point-of-use, and whole-house models. If a property is not already set up for gas fuel, then an electric unit would be the more cost-effective choice. The initial price of purchasing and installing a tankless water heater is typically high, but the long-term savings outweigh the upfront investment. And they can last for up to 20 years or more; a much longer life-span than traditional units. Tankless versions are a good fit for those who have very little space, environmentally-conscience, and looking to save money on future water and energy costs.
Tankless Water Heating
Tankless water heaters are also referred to as On-Demand or Instantaneous water heaters. Whether gas or electric, they use a simple process to heat water. When warm or hot water is requested, city water is sent into the property through a series of pre-existing water lines. At the same time, a powerful heating device called a heat exchanger is activated. The heat exchanger uses electric coils or a gas-fired burner to generate heat, and then transfer that heat to the water in order to warm it up. Heat exchangers are common devices used to transfer heat from one place to another. They are used in refrigerators, air conditioners, furnace systems, and even car radiators.
Once the water is heated to the demanded temperature, it is sent to the source, which can include faucets, dishwashers, washing machines, and more. Although it takes a minute for the water to reach the desired temperature, it saves a generous amount of water and energy. This efficiency is usually evident on energy, gas, and water bills.
If you are thinking about purchasing a tankless water heater, it is strongly suggested to consult a licensed plumbing technician for accurate recommendations and professional advice first. You might be better suited for a traditional style water heater instead. Get to know your hot water needs with the help of a skilled professional before making any final decisions about water heaters.
