The American Heat AH Models are considered by many to be a step ahead of the competition and a marvel of technology and engineering. As with all tankless water heaters, these units heat on demand, only when hot water is needed. A new, sophisticated flow sensor detects hot water being drawn when a hot water tap is turned on and water begins to flow. A series of sensors start gathering information / data, including incoming and outgoing water temperature, and the flow of water. This data is sent to an onboard microprocessor. This small computer calculates the amount of power needed to heat water to the point that you have set on the digital display. Set temperatures for anywhere between 80 Fº and 125 Fº and this machine busily goes to work making the temperature by choosing the power and the number of heating elements to energize. Water flows past the heating elements in their individual heat exchanging pods and you get the hot water at the temperature you have chosen. These AH Models are theromostatically controlled and built in safety features protect your children and you from overheated water if there is a decline in the water flow. Other electronic tankless heaters in the market use a manually set thermostat to control the temperature of the heated water. You have little control of the temperature of the water if there is an increase or decrease in the flow rate going through these machine.
The AH Models of American Heat will remain on until the hot water is shut off at the faucet. Once the sensors detect that there is no more water flowing through the heater then the power to the elements and the heater simply turn off.
All American Heat AH Model Tankless Water Heaters are manufactured in the USA.
All NEW for 2010...The new ETL, UL#499 and CSA approved AH Model with stainless steel heat exchanger.

Electronics and Computer Chip
This is the Brains of this system...programable and a very sophisticated micro-processor. The temperature of the heating elements and even which elements are activated are controlled by this processor. Your hot water is produced automatically by the known flow rate and the incoming water temperature. You set the temperature of your heater's digital display and the computer precisely controls the hot water production. |

Sensors
A series of sensors monitor the incoming and outgoing water temperatures. These sensors send information to the micro-processor and help mainaing the output temperature that has been selectd by the user. |

Time Proportional Triggering Devices (TRIAC)
The regulation of the power to each of the heating elements is through a device known as a Triac. TRIAICS allow the control of very large power flows with milliampere-scale precsion. TRIACS are mounted on a heat diffusing plate. Water flowing through the inlet water line cool in turn cools the plate. . |

Terminal Block
The Terminal Block is pre-wired with wires for hookup to your subpanel for easy installation. Complete instructions are available through a download os the Customer's Installation Instructions off the "Home Page." . |

Heating Elements
High powered heating elements are used to heat hot water as the water passes through two or three heating chambers. Each of the unit's heating elements are coated with stainless steel to resist dissolved minerals such as calcium and iron. |

Hi-Limit Thermal Protection with Automatic Reset
Each heating element is protected individually by its own thermal limit switch. This automatically shuts off the heating element if the water temperature reaches an unsafe level (about 140 F°). This not only helps protect the customer from scalding injuries but also protects the unit from unusual events such as power surges. Most of our competitors use thermal limit switches which must be manually reset if triggered. Automatic switching is always better than inconvenient manual switching. |

Heating Chambers/Pods
The AH Model heating chambers are the heart of the American Heat tankless water heater. All heating chambers or pods are constructed of copper and brass which are welded together with silver to resist the expansion and constraction of the metals during rapid heating and cooling. Each heating chamber is manufactured by hand to ensure precision.
Shown here in copper heat exchanger, the new version of the American Heat AH Models have stainless steel heat exchangers.

Aluminum Case
The entire AH Model tankless water heater is housed in a solid heat resistant, attractively-finished aluminum case, which protects the internal components from dust, debris and physical damage. All four corners of the unit can be securely mounted to a wall with built-in mounting brackets. |
