Was shocked at how easy it was to install. Works wonderfully.

I'm experiencing multiple issues with this water heater. It heats up for about a minute before turning cold, requiring us to repeatedly switch it off and on. I noticed that another customer mentioned a similar issue in their review. Additionally, there is a noticeable delay in getting hot water to the faucets throughout my home, and the unit cannot support two people showering at the same time.This is already our second unit—the first one had an electrical issue and had to be returned. Unfortunately, this replacement is also not functioning properly. Given that this is a brand-new construction home, I expected better performance. At this point, I'm seriously considering requesting assistance or a refund.

I was initially skeptical due to the lower price point—roughly half or more compared to competing models—but I don't need all the extra gadgets like blue tooth. This tankless water heater has exceeded my expectations. It effortlessly supports our 5-bedroom, 4-bathroom home, using a 3/4-inch Canadian cold water supply at approximately 55°F. Despite the lower incoming temperature, it heats water to 130°F almost instantly without any need to reduce flow or pressure, which was a common issue with the 80 amp electric model I previously used (I would only recommend electric units for single-point or very limited applications ).The build quality appears excellent, and installation was straightforward for this jack of all trades handyman who handles plumbing, venting, and gas connections on my own. Overall, this has proven to be a great purchase—both cost-effective and highly efficient. Add the 3/4 Inch IPS Isolator Tankless Water Heater Service Valve Kit. I bought the GASLAND for $89 cdn on Amazon. This allows for easy periodic maintenance.

Get the 100k btu. You will appreciate the extra flow when the incoming water is really cold and the faster heat up time.

Pleased with the purchase (so far) water temp fluctuation is a bit of an issue but we are getting used to it and figuring it out as we go. Seems decent but till will really tell.

This arrived very fast, which is good because my tank water heater died. After reading the instructions and looking at the unit I realized that the installation is very straight forward and fairly simple for any good DIY'er. The hardest part was removing my old 50 gallon Tank Water Heater. It fired up the first time and is working perfectly. I am adding a 2 Stage water prefilter in a few days to prolong the life expectancy of the unit.I only had to deal with the seller 1 Time since purchased, and they were quick to respond and solved my only issue immediately. For those that live in high altitude areas, I would recommend this unit for a 2-Bath home. Both of my showers run very well at the same time @ 6000 ft above sea level. I had to get a 1/2"NG to 3/4"NG converter and new 3/4' NG Line to connect to the unit, and am having no issues with NG Supply under heavy load. It only takes up 1/4 the space that my old water heater did. I am very pleased with the uniy, the seller and the service. :-)

The first one that I ordered had some electrical defects when I hooked it up. The system continued to beep on and off constantly and would not work. I filed for a replacement through Amazon and it was a good interaction. I received a replacement model which works perfect!! It's quiet and heats water in seconds.. I'd buy again!

I have a small 1200ft house with just my fiancé and I. This works great for our needs! Do research on the install as it’s not your normal water heater connections. I placed a larger 4” metal dryer vent hood through the exterior wall then routed the smaller vent pipe for the unit through it (vent pipe is smaller, 3”, so it doesn’t touch the homes walls). Water pressure is great, heat is very good, the only caveat is if your turning on and off your water (say washing your face) it’ll have to shoot out the cold water from restarting before it gets back to hot. Overall great purchase as it also should save money from not having a lite water heater 24/7. If you have hard water (I don’t) then maybe install a filter in line or flush your unit once a year with vinegar.

My five-star rating could change as this unit has only been up and running for a week. It was on sale for an irresistible price so I took a chance. It is rated higher than others at its non-sale price point, but it lacked the number of feedbacks that I would normally like to see. I eliminate dumb 1 and two star ratings but still pay attention to them. At 4.3 with no issues that seemed to be a roadblock for me, it was worth a try. I live alone so 3.6 gpm is more than enough flow rate, and 80,000 btu is plenty. Even two people could be using hot water simultaneously provided those outlets are low flow imho. It responds fast for my plumbing distances and stays on point with no temperature waffling...yet. My slight lack of confidence is based on the age old "you get what you pay for" mantra, but sometimes you get a gem. Other than awkward grammar at times, the instructions were pretty clear. MAKE SURE you have a gas line that matches or exceeds the btu rating of the unit. That was not clear in the instructions
