American Heat Tankless Electric Water Heater. These units are not point of use heaters! They will heat the water for the whole house simultaniously and replace that old spacious, limited hot water flow tank that we are all aware of. There are 4 models available at the best prices in the market, starting with the ADK-1 running 220v requiring a #6 wire and 60 amp breaker, delivering 120 degrees of hot water for 1 kitchen & 2-1/2 baths. Then there is the ADK-2 running 220v requiring a #8-#10 wire and a 37 amp breaker, delivering 120 degrees hot water for 1 kitchen & 1-1/2 baths. The ADK-3 running 220v requiring only a #10 wire (which is standard even in condo units) and a 30 amp breaker, delivering 120 degrees of hotwater for 1 bath. And last of the four is the ADK-4 running 110v requiring only a #10 or #12 wire and a 30 amp breaker, delivering 105 degrees of hot water for 1 single station. Make sure you check the correct model number before you make your purchase. A lifetime warranty registration form will be included in the box for your customer to be instructed on with no worries. Major appliance stores offer these type of units for double the MSRP of what these are priced. You will get a great response in your area by offering American Heat as a whole house heating solution for your customers!
