4 Advantages of Owning a Natural Gas Tankless Water Heater


natural gas tankless water heater, also called a demand water heater, heats water with a gas burner only when it is needed. As opposed to a storage water heater which heats a batch of water and stores it in a tank, a demand water heater only heats the water when activated. There are many advantages to using this type of water heating system, but in some scenarios it is not the most effective means of heating water. Natural gas water heaters, whether storage or demand, are the most cost effective types over the long run. Thus, natural gas as a fuel is already at an advantage to electricity and oil. This, combined with the benefits of a tankless system, makes natural gas water heating your best option. 


Why Choose a Natural Gas Tankless Water Heater

There are two primary reasons why you should choose a natural gas-powered tankless water heater. The first is that it uses natural gas as opposed to electricity or oil. The second is that a tankless system reduces overall energy consumption. Technically speaking, electric water heaters have a higher energy factor than natural gas-powered units, that is, efficiency rating. However, electricity is most often generated by burning natural gas which negates many of its clean qualities. Therefore, the advantages of using a natural gas tankless water heater outweigh its costs as well as those of the alternatives.


Advantages of Owning a Natural Gas Tankless Water Heater

  • No Standing Water Loss: Because there is no tank in which heated water sits and eventually loses its heat with lack of use, no heat energy is lost with standing water in a demand water heater. By some estimates, this reduces overall consumption of energy by up to 15%.

  • Efficiency Increases with Efficient Fixtures: Combined with low-flow faucets and shower heads which reduce the amount of water that is emitted with each use, tankless water heaters work extremely well. Because tankless water heaters may have a limited flow rate of hot water, the less efficient the fixtures, the lower the number of gallons of hot per minute of use. 

  • Hot Water Does Not Run Out: While the rate of hot water flow can be slower especially with a lot of use, a tankless water heater does not run out of hot water. There is no tank with a batch of hot water sitting on cooler water. As needed, the gas burner heats water and pumps it to the faucet. 

  • Natural Gas Tankless Water Heaters Are Not Limited by Wiring: Electrically-powered tankless water heaters need a lot of current to power a residential home. The wiring is not up to the task in most cases. Natural gas tankless water heaters, on the other hand, do not have this problem.

Natural gas is already a more efficient means of heating water in a home. While there are cleaner forms of electricity generation such as wind, solar and hydroelectric, by far the most electricity is created by burning natural gas. Long term and yearly costs are lower with natural gas. Add to that the advantages that tankless water heaters have, and you have a cost effective, energy efficient system for your home.



Siliphos inhibits or binds calcium and magnesium hardness minerals, preventing them from precipitating out of solution and building up on metallic surfaces. Siliphos also forms a thin protective layer on the pipe wall or metallic surface with helps to eliminate hardness build up and corrosion. Average cartridge life is 4 to 6 months.

Pre-filtration is necessary when utiilizing tankless water heaters to prolong the life and efficiency of your equipment. Many tankless water heater manufacturers will void the warranty if the water supply is not pre-treated to eliminate any sedimentation, or scale build up that can damage your equipment.
