Being that the Takagi T-K4-IN-LP is meant for mid-sized or larger homes, It may be too large for a smaller home. If you do not need a tankless water heater capable of producing up to 8.0 GPM then there are smaller more inexpensive alternatives that will better suit you.


All in all the Takagi T-K4-IN-LP is a great overall value. It doesn't have all the bells and whistles but for the pricing is a great bargain.
