5 Stars. There are 5 of us and we are very happy with the hot water. After searching for information for almost a month on low-consumption hot water systems, we decided on b. heat only hot water. Delivery in just 3 days from the web order.

Delivery was delayed a day due to the height of the package but then everything was perfect.
