Cons

While the Takagi T-H3-DV has high energy efficiency and ten gallons per minute hot water output, it has a few disadvantages which we shall outline below.

  • Expensive Installation

    The Takagi T-H3-DV is costly to install. One of the reasons for the high installation cost is because it runs on gas. Most homes do not have gas pipes compatible with the heater. So, you need to retrofit your gas and water pipes to fit the unit.

    Also, the unit requires a combustion vent to evacuate the smoke produced by the burning gas. However, the PVC venting ensures that the venting is cool at all times and nothing leaks out of the pipes.

    The high installation costs can also be attributed to the fact that you need professionals to install the Takagi T-H3-DV. Additionally, the heater requires some hardware which is not included in the box. However, it can help you save up to 50 percent on water heating bills. The durability of the product ensures that you will enjoy many years of excellent service.

  • Temperature Drop

    Like most high output tankless water heaters, the Takagi T-H3-DV may be slow in providing water at first. The water temperature may drop by one or two degrees for a short period during heavy use. However, the unit quickly compensates for the loss, and you may not even notice the change.

Summary

The Takagi T-H3-DV is a super performer in the tankless water heater industry. It can deliver an impressive ten gallons per minute and has an energy factor of 0.95. Also, it comes in a sleek, little box which makes installation in tight spaces a breeze.
