Excellent unit, but Read The Directions!

Reviewed in the United States on October 20, 2014

Verified Purchase

I Purchased this unit August 18, 2014 thru Amazon, excellent price, excellent service. I decided to go with professional installation, not cheap but a smart move. I wanted this in my part-time vacation cabin, so it had to operate on propane. The reviews I read on this model were very favorable, so I decided to take the chance. Finding a licensed plumber that would do it was not easy, as many had had bad experiences with other tankless water heaters (just read some reviews of "other" brands). After obtaining some additional parts to complete the installation, it was done within an hour (very fast) and after some purging of the lines and a few adjustments, it works just fine. My plumber was impressed with the quality of this unit (he had actually installed several other-brand tankless units) and the prompt, efficient service from the vendor (to obtain needed hook-ups), and the clear, concise, detailed instructions so that he would recommend this unit to other customers. There is a learning curve associated with using this unit, so read the instructions, especially the part about maintaining flow rates during use. I have a low-flow shower head, and must keep the sink faucet running during showers or the minimum flow rate is not maintained. The first time I used it, the unit went from hot to cold suddenly. BRRR! I quickly turned the shower selector back to tub, and the hot water came right back. Lesson learned, change shower head or run sink faucet while showering. There's plenty of hot water, it's very quiet, and so far functions flawlessly. From stone-cold to hot water is about 10-15 seconds, not bad at all!

Beautiful, Wonderful, Awe Inspiring.... Did I say, "I cussed like a sailor"?

Reviewed in the United States on April 9, 2017

Verified Purchase

This is an excellent on demand water heater. The instructions were hard for me but I'm no professional either. This was a replacement for an old on demand that had two settings: on super hot or off. So, I put this in along with a water filter because our water has a lot of calcium in it. It was worth the trouble because without filters the appliances last five or so years which is no fun!

Here is the hard part and how I managed it. The system required a regulator to keep the pressure where it needed to be and I've forgotten the pressure cause this was six months ago. Needless to say, the regulator was over kill because the system has a regulator and the propane running in is also regulated to the psi required for household appliances. But, being a novice means being really really really sure of what I'm doing. I am 98% sure I didn't need a regulator.... But 2% sure was all I needed to install one ($55) to be 100% sure it won't break or blow up! Breaking is bad, blowing up is worse!

Another problem was all the pipes didn't fit! Ha! Ha! Where is my plumbing truck with all my fittings? Oh, I'm a novice so I went the hardware store (actually two hardware stores which made things delightful - I cussed like a sailor.....). But guess how much money I saved? The cheapest plumber wanted $3,000 dollars for the install and wanted to put his own odhwh in. Said it would take him, and him alone one day, two days max.... Three grand is great money. I guess these plumbers ride around all day giving super high bids and waiting for some poor old lady to fleece. Anyway, I checked his quality and his hwh got three amazon stars and a bunch of "this is a crappy water heater", and his was a name brand! So, I did it myself. I am a sailor so I cussed like one. But I did it! And it works great. I actually took a bath... Ha ha... It's been many years... Now I might take a bath monthly... Naww! Did I say I cussed like a sailor?

Here is what I really like: I can set this on my temperature and run the water at that temp. And yes, it can be really hot if you want it hot. I've got it set at 105 degrees unless I'm doing dishes and I crank it up past 125 degrees. I think the maximum is 160 which is hotter than a .... Tomahawk screaming toward some baby killer... Go Trump Go! Let's get that fat moron in N. Korea real soon too!

Amazing performance with extremely low LP usage.

Reviewed in the United States on October 21, 2015

Verified Purchase

Great deal on a compact, instant on water heater.
This takagi replaced a larger, more expensive, less reliable, and much noisier model in our home. When running the fan is audible only if you cock an ear towards it if you have it mounted in a closet as we do. Outside the exhaust is noticeable but that is not even a consideration. LP usage has gone so far to the low end, my provider of LP wants to increase my cost per gallon unless I install another LP monitor or fireplace to keep my usage levels up.
Installation of the actual heater and cleaning valves was done by a master plumber even though it would have been doable for an amateur plumber, my biggest hassle was the cost of the stainless steel exhaust venting and making it work for holes in the wall from previous installations of different sized water heaters. LP plumbing was done by a master gas tech so we could add piping to install a cast iron gas heater/stove in another room at the same time. This is something you should pay a pro to do no matter how comfortable you are with your home improvement skills. If there is a major problem, your homeowners policy will probably not cover it if you installed it.

Failure after 8 months of use

Reviewed in the United States on November 15, 2018

Verified Purchase

The unit worked well and provided plenty of hot water for 8 months. Without warning it will not light. It provides no error codes or indicator as to the problem. The cost of service call is more than the unit is worth. I do not recommend this unit for anyone who wants hot water for more than a few months!

Multi use hit water heater

Reviewed in Canada on July 26, 2020

The only draw back is it needs certain flow rates to turn on.. using a small sink tap takes along time to get hot water. We have had 2 showers laundry and sink going and the 6gpm takagi worked flawlessly.

If you are on a farm or process birds At 145 f you can use water from tap to direct scald the chicken turkey or duck in no time to get feathers off at 170 and thermo Stat control it can be used to sterilize knives and other meat handling stuff.

Compared to our other instant hot water (eco max) it does same job a bit better but for 30%less propane.

Used my previous Tekagi Jr for 8 years with only one minor problem. If this new Tekagi Jr 2 performs as well, my expectations will be met and exceeded. (New one just installed Jan/18, and appears to be working well -- no hiccups.)

Bought this to replace an earlier one by another manufacturer. This one produces water at the desired temperature and is relatively quiet. One little problem is that it shuts down 1 second after it starts occasionally and has to be restarted

This is the best way to get hot water that I know. It was easy to install on my propane system. as a bonus I am saving on propane bills not having to heat a huge tank of water.
