I couldn't be more pleased

I couldn't be more pleased with the performance of this hot water heater. Though it's the smallest and least expensive of the 220 volt heaters it performs marvelously for my needs, I'm single and live in a small cabin so it provides all the hot water I need for kitchen and bath duties. I'd been foolishly and wastefully keeping 30 gal. of water heated 24/7 with 220. I should have switched over years ago. I can stay in the shower for a week if I feel like it, with the water as hot as I want it, That says it all about this product and it's no bigger than a good sized dictionary!

Works great!

The heater has performed perfectly for the last 5 months. Seems to never run short of hot water. Inexpensive, easy to install and efficient are some of the adjectives I'd use to describe this product. Very glad I found this heater. Definitely would buy this again.

Great Invention

First of all, this product is a great invention. No more bulky water heaters for me. I hang this on the wall in the basement. The sleek stainless steel is a plus. the water temperature DIGITAL display is very precise and change water temperature. MAREY'S customer service department is excellent as they respond to email in a day and let me extend my warranty by 1 week. I WOULD HIGHLY RECOMMEND THIS WATER HEATER, THE WATER HEATS UP INSTANTLY!
