#2. Limited hot water supply

While a tankless water heater is consistent in hot water supply, it only provides a few gallons of water. It works best for single-use, but it’s troublesome when used by two or more people who use water. It runs out of hot water; it takes time to resume the water supply.


#3. Proper vent needed

Install a suitable vent with it. Moreover, it requires venting it outdoors with a conventional exhaust fan or direct vent, increasing the installation cost. Find out how to vent a water heater.


#4. Extra maintenance is needed

Yearly maintenance is necessary when running a tankless water heart, which is part of your obligation as the owner. A low operational cost brings less consumption of energy. This task counteracts the savings acquired by lower energy consumption.


#5. Demands significant setup

A significantly complete setup is required in a tankless water heater installation, including upgrading or expanding gas supply or water supply pipes. A suitable configuration of electric supply is even needed. Thus, hiring professional electricians and plumbers is essential in installing it, increasing the upfront cost.


#6. It does not start instantly

A tankless water heater does not start instantly like when you need a quick bath; it takes time to increase the water temperature. Just imagine if you’re in a hurry to attend a job interview; a tankless water heater does not seem a promising avenue for heating water. You’ll wait for a long time, so the tankless water heater gets water coming from the cold line. It must then be heated and thrown into the shower.


#7. Competitive yet most expensive

Understand that a tankless water heater is the most competitive but the most expensive, as this is true considering the many traditional water heaters to find and store. It ordinarily has a less or similar property than a standard geyser.


#8. Pilot light wastes energy and consumes pilot light

A gas supply form of a tankless water heater has a pilot light that consumes, plus wastes, energy. Nonetheless, it has nothing to do with heating water. Its design starts in the heating process. But with a conventional water heater alongside storage, the pilot light does not begin the heating process. It somehow increases the water temperature.


#9. Trouble in power failure

If your goal is to maintain the warmth of the floor during the winter season, a tankless water heater seems a great option to consider. But if there is no electricity and there is a storm, the device will not switch on. It won’t heat water as well. It will not heat water at all. A heater that runs with gas requires an electric control panel for its operation, which the tankless water heater lacks. If a power outage occurs for days, it will be a troublesome experience.


#10. The need for extra equipment

If a water softener is necessary, you want the tankless water heater to work correctly. That means you must set extra equipment that adds to the unit’s price. It’s beneficial in saving space, but the vast softener accumulates more space. Add this softener, and it requires more space than a conventional water heater.


#11. Not usable in the northern climates

A tankless water heater uses an instant raising modulator that switches the temperature from 50 o to 60 o. Nonetheless, you do not carry out this easily if you’re from the northern climates.
