We Have Tankless Water Heaters for the Far North--Northern USA, Alaska & Canada.

Careful consideration of your hot water needs and flow requirements are needed to determine the use of either the ADK Series or the AH Model Tankless Heater Units in our store. Contact Us if you need assistance.
The Super ADK-1, is the work horse of the American Heat line of tankless water heaters. Designed for use in the sunbelt or southern portion of the United States, the Super ADK-1 line of tankless water heaters can be used in multiple configurations to provide a greater heat rise for our customers in the colder, northern areas of our country. One ADK-1 American Heat unit can be used in applications supplying one shower or possibly a faucet and a shower with water restricting shower heads of 1.5 to 2.0 gpm. The heat rise for the Super ADK-1 around 95o F for one gallon per minute and 64o F in 1.5 gallons per minute. So, you can see that the heat rise in a single ADK-1 is restricted to less than 1.5 gpm if the incoming water temperature is 45-50o F. The solution in the past could be resolved with different American Heat ADK heaters and configurations of those heaters. For instance:
-
Two American Heat ADK heaters can be arranged in parallel where the incoming cold water pipe is bifurcated into a supply for each heater. Shut off valves on each cold water supply and each output side of the hot water supply assures a backup to the overall system. If one ADK unit fails then the second ADK unit could be used as a single heater for the home. The parallel arrangement or configuration allows a greater flow or volume on the outlet or hot water side. Each requires a separate two pole, 60 amp circuit breakers. Consult an electrician for this type to assure adequate power in your electrical service panel. Use the heat rise chart vs. gallons per minute to help evaluate your needs or situation. Use of a water restricting shower head with as little as 1.5 to 2.0 gpm is very useful. Note that you may need more power yet and you can get that by checking our AH Tankless units on this site.
-
Another configuration uses a ADK-1 unit such as the Super ADK-1 unit in tandem with a smaller ADK-2 or ADK-3 unit. The smaller unit can be a "pre-warm" heater which passes along warmer water to be further heated by the next in-line Super ADK-1 unit. Again, the use of water flow restricting devices help slow the flow of water through the heaters to give a better heat rise to that water. Once again, get the consult of a qualified licensed electrician for this type of arrangement.
-
The use of the larger AH American Heat units offer more flow through their 3/4" inlet and outlet vs the ADK unit's 1/2" inlet and outlet. The AH series of heaters are self-modulating. It uses an onboard computer to regulate the heat that you manually set with a digital keypad. The AH series offer more flow and hotter water. Units range in size from 11 to 27 kilowatts. The larger AH Units are CSA approved for their use in Canada. Click Here to link to the AH Tankless Heaters.

Remember, more than one tankless unit may be required dependant on your cold incoming water and the amount in gallons per minute required in your household.
