Use Tankless Water Heaters To Save Energy

Generally, heating water for cooking, washing dishes, bathing and laundry may consume more energy at home. An estimated of 20% of a home energy use is from heating water. If you use a tank water heater, you may pay extra $450 each year

How do conventional tank water heaters work?

Tank water heaters store the hot water in the tank and maintain the temperature between 120 degrees – 140 degrees Fahrenheit). If no water is drawn from it, the temperature will drop and then the heater will heat the water periodically to maintain the temperature. And when the heat water is drawn from it, the cold water will supplement in the tank and the temperature will drop and the heater needs to heat the water again.

This heating process cannot avoid standby loss which means the energy is wasted to maintain the temperature in the tank, causing an estimated of 20% of wasted home energy use annually.

How do tankless water heaters work?

Tankless water heaters don’t have tanks to store hot water. They can rapidly response to your requirements, which is called “on-demand water heating”. When you open the faucet, cold water flows into the heater and a sensor will turn on the heating coils or heat exchanger. The heating coils will heat the water to the desired temperature. You just need to close the faucet to shuts down the heating coils. The water can be heated to the desired temperature in 5 seconds. For tankless ones, there is no standby loss, which can save much money and cutting your family’s energy bills.

Pros:

  • No standby Loss
  • More energy efficient than conventional ones
  • Don’t waste water due to its rapid response
  • Don’t worry about running out of hot water when you are in a shower.
  • Have twice life span than conventional ones, up to 20 years
  • Tax benefits in some states

Cons:

However, besides the advantages, they also have some drawbacks too. If you choose a gas heater, continuous heat water demand may reduce the efficiency of the pilot light due to keeping it light continuously. If you want to bathing at the time washing dishes or clothes, you need to choose products with high GPM, or they may not work. At last, the initial cost of a tankless one is more than a conventional one. If you need a tankless one for multitasks at the same time, you may need to pay more.
