Answer: 
Per the supplier, locate the water heater in a clean dry area as near as practical to the area of greatest heated water demand. The water heater and water lines should be protected from freezing temperatures. Do not install the water heater in outdoor unprotected areas. Unit must be installed in a vertical position ONLY with the water fittings pointing horizontally. If you need further assistance, please contact us at 1-800-Grainger.

i am interested to know if i replaced a 150 gallon water heater, would this be the appropriate model to do so with? i do understand there would be many available models however in reading the "specs" how can i determined which model or size would be best in replacing the water heater i have already. also because they run on electricity, do they have an "energy saver model? one that may qualify for potential rebate from energy company?

Answer: 
For installing a tankless electric water heater here are a couple of things you need to consider. The voltage and amps that is available from the service panel also the incoming water temperature to the heater. The temperature rise in degrees Fahrenheit (temperature rise is added to the incoming water temperature) and have many gallons per minute required for the application or multiple applications. Sometimes more than one tankless water heaters are plumbed in for greater volume of water. The units are considered energy saving because they only turn on when hot water is required check energy,gov for rebates for your state.
