Tankless water heaters in Fort Worth, TX are also called demand-type water heater because of their instantaneous hot water supply. Unlike the traditional water heaters, which only provide hot water once the tank is filled with hot water, tankless water heaters have a continuous flow of hot water, running through the faucets. In this post, we will explain how tankless water heaters work, what their mechanism is and the criteria to choose a water heater for your home.

How Tankless Water Heaters Work

Tankless water heaters in Fort Worth, TX have high-functioning burners to simultaneously heat up the water as the cold-water flows from the pipe attached to the unit. There is no water storage unit, as the name suggests. All you have to do is turn the tap on and cold water will flow to the unit through pipes and pass through heat exchanger that will heat it up on its way to the faucets. It has two pipes: one that carries cold water from the tap, with the heating unit in between, and second pipe that comes from the other side of the heating unit and goes back to the tap.

Tankless water heater either has a gas burner or an electric heater. However, unlike traditional water heater, the flow of water is limited with tankless heater because of the pipe’s capacity to carry water in one go.

Normally, the rate of tankless water heater to provide hot water is between 7 – 15 liters per minute. The gas-fire version of tankless water heaters has higher flow rates as compared to the electric versions. However, the ones with gas burners do have a limitation when it comes to simultaneously providing water for multiple uses. For example, if you are taking a shower and there is someone using the dishwasher at the same time, then it can put a strain on heater’s limit.

To deal with this issue, you can get two or more systems installed in parallel, depending on your family size and usage. To overcome this problem, you can install two or more tankless water heaters, connected in parallel for simultaneous demands of hot water.
