Great product

I absolutely love this product, easy to install it can supply hot water to bathroom and kitchen simultaneously, with a smart touch control panel that features on/off,temperature display and adjustment and also error codes for easy troubleshooting.

Easy to install, great energy efficient water heater

I got this water heater to put in my shop. I have always wanted hot water in the shop, but didn't want to waste floor space with a conventional tank heater. This one takes up very little wall space and is super easy to install. This model is for LP and since I already had propane in the shop, it made the job easy. Three connections to make on the bottom, cold water supply, LP gas supply, and hot water out. The vent is on the top. Electrical supply is just a cord you plug into a GFCI circui...

Good propane tank water heater

Would Recommend

This is the water heater I was looking for my small shower next to the pool area. This is perfect in size and well priced and good enough for light usage. 100% worth it. The water stays hot for a very long time and runs off of propane which makes your life a lot easier

Great, easy to use, easy to install.

Would Recommend

Great water heater, extremely easy install and its not too heavy so you can do it alone. Display is easy to use and the design is small enough to fit in a shallow closet. The cord for it is also long enough which is handy.
