    • Great water heater!!! Works as it should!

Review Image by Ty Ty
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. ... show more

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.

Replaced a 39 year old Bosch Aquastar with this one , could not find parts any longer. Had to buy new fittings as the old one had 3/8 connections for the propane and water. Total install time 1 hour. Heater works well and supply enough water for a family of two. It is much smaller than the Aquaster saving space in utility room. Will see how it performs and works in the long run. Currently I am very satisfied with the performance . ... show more

We ordered this for our hunting camp after the old hot water heater passed away. It was a bit tricky to install but customer service was amazing and helped amend the issue we were having. I recommend if you are not experienced in installing something like this get someone who knows to help you, because you do need to know about these things to ensure you do not mess up. ... show more
