We have tried to review the most key factors that will help you understand whether a tankless system is worthy. Off we go!

1. It Heats Water Directly Without a Tank

Your traditional tank water heater stores water over time for further use. Tankless units, in turn, do not need any storage to deliver it then for the rest of your household. For instance, when you turn on the hot water tap, the cold water runs through the heater and is heated by either a gas burner or electric heating element. Only after, it is distributed to the taps around your house.

Then, as was hinted above, thanks to a tankless construction, you save space in your basement or other places. You simply mount it to the wall, and can even hide it from the others’ eyes.

2. There Is a Steady Flow of Hot Water

About 2-5 gallons per minute to expect with tankless units. Traditional units deliver water until the tank is empty. Tankless systems provide users with a steady flow of hot water. Some gas units can satisfy you with higher flows compared to electric ones. Besides, storage tank heaters may easily run out of hot water taking into consideration the events when several sources use it simultaneously.

Yet, let’s also introduce a problem in this case. For instance, if homeowners take showers, or run a dishwasher at the same time, the hot water can be not so hot or there will be not enough pressure. So, homeowners have tendencies to install a few tankless water heaters if they have a big demand for water.

3. Panels for Optimizations

By finding a contractor, and installing such a heater, you should specify what settings you expect to have.

Then, it is about air supply blockages when the heater experiences problems with venting. Homeowners may also face problems with ignition failure.
