Heating Basics for Residential Applications

Understanding the basic principles of heating systems is essential to selecting the proper heating system for your application. This information is listed below.

 

Safe, Dependable and Energy Efficient Furnaces

All of our furnaces are pre-tested before they leave the factory to assure reliability of operation. With efficiency ratings from 80% to 96% AFUE, these high quality furnaces can reduce heating costs up to 30%. All of our furnaces feature electronic hot surface ignition and are Air Conditioning ready with multi-speed blower motors. For top performance and safety, the control module monitors the overall operation of the furnace, and the built-in self-diagnostics help make servicing our furnaces easier. Hamilton offers a Universal Plenum for heat only applications and Custom Plenums for our indoor Coils to simplify installation.

Selecting the proper FURNACE
Selecting The Furnace MODEL

Determine the direction in which the heated air flows or is discharged from the furnace. It will either be an Upflow, Downflow or Horizontal Model. (The diagram to the right shows these models in some of their typical applications.)

 

Please NoteMulti-positional style furnaces are designed for ALL installation applications and required minimal conversion.

 

Selecting The Furnace TYPE
The Type of the furnace is determined by the fuel source that runs or operates the furnace. Select either Natural Gas, LP Gas (Propane), Oil or Electric.
For Natural Gas or LP (propane) fired furnaces, choose between an 80% Standard Efficiency Furnace or a High Efficiency 95.5% Furnace. Forced Air Electric Furnaces are also available, as well as 80% Efficiency Oil Fired Furnaces.

 

Selecting The Right Furnace SIZE

You can refer to an estimate or proposal from a local contractor, refer to the size of your existing system that you may want replaced, or use the sizing estimation chart listed with each furnace type within this web site.  A properly sized furnace will ensure your comfort. Therefore, it is important to never undersize. Always go to the next larger size if necessary. Oversizing by more than 20% can negatively affect the efficiency, and the operation of a furnace.

 

Please Note:  When sizing equipment for mobile home applications, refer to the data plate located in the electrical panel or kitchen cabinets.  For further assistance, contact Hamilton's customer service department.
