Propane Gas Tankless Water Heater, MIZUDO Up to 4.3 GPM, 100,000 BTU, CSA Certified, Indoor Installation Instant Hot Water Heater

UPDATE: I have abused this machine for almost a month now running it at max temperature taking 2 10 minute showers each day between me and my partner. It is extremely efficient, we use small 5 gal propane tanks that and they last roughly 2-3 weeks of us using them a lot. We also hand wash our dishes and it still manages to last super long. This is one of the few indoor built instant propane water heaters on this app and website. It does not disappoint, the price tag reflects the quality. It gives instant hot water and works amazingly as advertised. I've been using this for showers over the past week and it works great. It is super easy to mount and although it doesn't come with the fittings and proper connections for gas or water you can easily find these at your local hardware store. It will cost a little extra but I guarantee after you try it you will love it. I have this unit mounted in my camper that I live inside all year around and it is the greatest upgrade I've done to this place.

Easy to install and works great. Only downside is it has to be turned on via the indoor control panel after a power outage. Otherwise, great product so far.

Use this in a remote cabin-like scenario. Replaces a small RV tank water heater. Very easy to install. Love having nearly limitless hot water, not having to ration it. Might have rated it higher, but am waiting to see how it works for the long haul.

I purchased the 80,000 btu version of this water heater. I love it! It's been about a week since I installed and it is still going strong and working like it should. Whoever said this can't be used as a whole house water heater was wrong. It took some getting used to because I used this to replace my old 40 gallon tank water heater, and like all tankless water heaters there's a bit longer of a delay in getting hot water to the faucets. However once that hot water is flowing it's amazing. I took the longest hotest shower I think I have ever taken in my life!!! The only other quirk is the flow rate. Which I expected since I chose the smaller unit for a whole house. The flow rate is plenty to run a shower, run the washing machine, run the dishwasher or the kitchen and bathroom faucets. However when filling a bathtub there is no water restrictor so the tub has to be filled slowly. It still only takes 15-20 minutes to fill my cast iron tub. A little bit longer then when I had a tanked water heater but a small trade off for unlimited hot water! The only other thing to keep in mind is this water heater doesn't have a fresh air intake, it used air from inside the house. If your house is sealed up well and well insulated it may not be the water heater for you. My house was built in the 20's so I had no worries about not having a fresh air intake.

It works awesome, now just need to worry about my water bill because it's never ending hot water makes it hard to leave the shower

Didn't heat water like described in add. Only 1.5 gal per minute. Seven weeks after installation it shut off with E5 error code. Will be checking to see if it is the fan or control box or both that has failed. This heater was not heavily used and it failed already. Once again I will not have any hot water except for what I heat on the stove. Turned out to be control box.I am returning product. I have not received a refund yet.DO NOT BUY THIS PRODUCT. DEFECTIVE.

It’s easy to install and had hot water with sink on full blast

I would have given this 5 stars if the gas would have been 1/2 mip. I ordered this in January knowing that there was a good possibility I was going to need one at one of my various properties. It took me and a buddy of mine longer to drag the old tank water heater out of the house than it did to hook this up. If you value nothing other than time, this took minutes to install. Seriously... we did have to drive a mile to the hardware store and buy a couple of fittings but it took 10 minutes to hang it on the wall and hook everything up. Had they used a standard fitting for gas on this, it would be 5 stars. If it makes it 5 years it deserves 5 stars. Haven't even read the instruction yet, we just hooked it up and plugged it in and it worked so much easier than a tank water heater. I think I'll order a second one.
