Rated 5 out of 5 by from AO Smith Hybrid water heater As a custom home builder i'am excited about new energy saving products. I recently installed AO Smith's Hybrid water heater (SHPT 50) in my own home as a test model. Installation was not hard as it took me approx. 4 hours. I expect to save as much as 50% in energy costs over my old water heater.

Rated 5 out of 5 by from Awesome water heater! I just installed it today so I can't say how much energy savings I will net but I'm really excited about the potential for 280-300 a year in savings with this unit. I did install it in my basement so I am slightly concerned about it being able to draw in adequate heat but I think it will do great in the summer! Plus it will also cool the basement and help dehumidify as well, which was a huge plus for me since one of my other big energy eaters is my dehumidifier. I can't say enough great things about this unit thus far, it heated the water very quickly initially and we'll give it a good test tonight with showers for the kids and I. But as of right now, I'm one happy customer and certainly glad to have hot water again!

Rated 5 out of 5 by from Powerful, economical water heater This is the second A.O. Smith heat pump hot water heater we have purchased; one in Florida, one in North Carolina. We have been very satisfied with the performances of both of them.

Rated 5 out of 5 by from So Efficient! We've only had it a week and we love it! We went from a tankless oil burner (that was also our back-up heat, we run off of wood-stove primarily) that would kick on and off in the middle of the night. We didn't need the heat, the water didn't need to be hot, but run it would! So we bought this and had it installed as our primary hot water and the oil as back up. We are going to be saving almost a $1000/year not paying for hot water via oil! this runs quiet, the tempature is accurate and consistent - it works great! so happy we made this choice, Its dehumidifying our cellar and we are getting a rebate from the state! Love the vacation and alternate modes it offers.

Rated 4 out of 5 by from New SHPT 50 Water Heater / Heat Pump Purchased this product due to plumbing store recommendation and rebate. One BIG issue is the cold (in) and hot (out) connectors are on the lower side and bottom of the tank....looks fugly after install and you need more room to install due to piping run. Minor issues is that you need a unique screw head for the electrical fitting (some time of hex) and the noise of the heat pump fan. Fan noise can be heard...and I'm partially deaf. My hope is that the lower energy costs will outweigh the cons of the installation.

Rated 5 out of 5 by from Great Water Heater! I have only had the heater for a month, however, it has been great. The electric use is down and I get more than sufficient hot water on Efficiency Mode, at least right now during the summer.

The Voltex® Hybrid Electric Heat Pump reduces water heating cost by up to 66% through an innovative design that pulls environmental heat while dehumidifying and cooling the ambient air at the same time.

The SHPT-50 uses heat pump technology to deliver tremendous savings, by generating heat through the heat pump technology instead of the heating elements. It offers premium features including a user-friendly display, vacation mode to save money while you are away, and a heavy duty anode that protects your tank for 10 years. In addition to the heat pump technology, this model also has two heating elements that help the water heater recover quickly during periods of high demand.

How it Works

The Voltex Hybrid Electric water heater utilizes heat pump technology to provide a more efficient way to heat water with electricity.
• Heat from the surrounding air is pulled into the heat pump through a fan at the top
• The heat is absorbed by the refrigerant in the heat pump's evaporator coil
• The temperature of the refrigerant is increased as it is pumped by a compressor
• Hot refrigerant is passed through the copper condenser coil around the tank and transfers the heat to the water
