Takagi T-KJr2-IN-LP tankless water heater
A benefit of this unit is that it can use either propane or natural gas to heat water. The factory-default setting is natural gas. Changing it over to propane may require some change in lines, but it can be done by a professional plumber with minimal difficulty.
Many customer reviews assure potential buyers that this is more than adequate for a household. Comments even reference using multiple things at once (e.g. a dishwasher and a shower), without seeing a change in water heat or pressure. However, for those living at higher altitudes, there are certain pressure settings that may need to be adjusted in order to maintain a steady water flow and temperature.
- Small size
- Easy installation
- Maintain performance with multiple water outlets running simultaneously
- Different altitudes impact unit performance
- Venting and valves required for install, but not included in initial purchase
- Propane setting is not intuitive
- Noisy
