Cons

  • Installation

    Deciding what type of water heater will work best for you means that you should also consider the installation process. A lot of times water heaters are installed by a novice, simply following the given instructions for the water heater. There is also the option to have professional assistance, especially if the manufacturer requires it in the product’s warranty. For a tankless water heater, the upfront cost is typically higher than if you go with a water heater tank. The Takagi model is no difference since this T-H3S-OS-N is powered from natural gas. This installation will require special venting. With the maximum BTU of 180,000 this will require a larger gas line than many may have already installed in their home.

  • Water Limitations

    Selecting the right size for your home is crucial to receiving hot water on demand. The Takagi Tankless Water Heater produces 8 gallons of water per minute. This will limit how much hot water can be used at the same time. With tankless water heaters, the water heats up as it passes through to come out your shower or faucet. Compared to a water heater tank, you would have a known set amount of hot water available. Also, you can better gauge how much the water heater can handle. This Takagi can supply hot water simultaneously to three bathrooms in warmer climates and two bathrooms in colder climates.

    When researching hot water limitations in a tankless water heater, the topic of the climate you are in will always arise. Your climate affects the groundwater which flows through the Takagi water heater and will heat the water on demand. Colder climate means that it will take longer for you to receive hot water through your tankless water heater. This downfall is not experienced with a water heater tank since water is sitting in a tank at a set temperature.

Water Hardness

The last thing to be aware of when purchasing any tankless water heater is the issues it has with hard water. Hard water does damage regardless of what type of water heater you use however with the tankless water heater there are a few issues that need to be addressed. If you are living in an area prone to hard water, there is the possibility your Takagi T-H3S-OS-N can experience these issues as well. It is recommended specifically with this brand to not use with water that has over 7 grains of hard water. The constant use of hard water in the Takagi will more than likely damage your unit causing it to be replaced way sooner than its normal life occupancy of 15 or more years. A way to combat this would be to regularly flush the water heater system.
