great space saver, works great
powerful for its size
I installed this unit in my 2/1 1960's condo replacing a 30gal water heater. What a great product! The install was easy i had to upgrade my breaker to a 60 from a 30 which meant upgrading the wiring gauge, which wasn't hard at all. I have hot water on demand now that never runs out! my 30 gal tank would only provide about a 5 min shower now its as long as i want. I have to fill my tub with free flow hot water at only half flow but to keep hot water but i figured as much from such a small unit. overall it was very much worth it to ditch the hot water storage tank and have hot water on demand for as along as in need it. If i were to try to heat a larger house with 2 or 3 baths I would suggest a larger unit but the product is GREAT!!
Hi, Thank you for tanking time to write this review, we appreciate the great feedback and we happy to hear installation was easy and you are enjoying or new water heater. Jennifer
I HAVE INSTALLED TWO OF THEM SO FAR-2 DIFFERENT HOMES. THEY WORK VERY WELL IN FLORIDA-UNLIMITED HOT WATER.
