HEATING AND COOLING APPLIANCES

Air Conditioning Condensate Disposal

Condensate Description
The process of removing heat from the air is often called air conditioning. Water is a byproduct of air conditioning because water vapor condenses out from the air when the air temperature is reduced. In areas with high humidity, air conditioning can produce signifi cant amounts of water. The water removed from the air during air conditioning is called condensate. Read the full Topic

Coolant Access Caps

1. Install locking-type, tamper-resistant caps on refrigerant line access ports located outdoors or provide another approved means to prevent unauthorized access.

Electric Heating Elements Installed in HVAC Ducts, Heat Pumps, and Air Conditioners

Electric Heating Element Description                                                                                                                                                                                                                                                                        Electric resistance heating elements are often installed in heat pumps when they are used cold climates. These supplemental electric heating elements activate if the temperature becomes too cold for the heat pump to provide adequate heat. These elements become very hot and proper installation is important to prevent fires and electrical problems. Read the full Topic

Electric Radiant Heating Systems Installation Requirements

Electric Radiant Heating Description
Electric radiant heating systems provide heat to a single room. They usually have no fan and provide heat by natural movement of the heated air and by thermal radiation. They are common in small seasonally occupied buildings, some rural homes, and in buildings without ducts for forced-air heating and cooling. These elements become very hot and proper installation is important to prevent fi res and electrical problems. Read the full Topic

Evaporative Cooling Appliances Installation Requirements

Evaporative Cooling Appliances Description
Evaporative coolers (also called swamp coolers) are usually located on the roof or on the ground outside the home. They work by running a stream of water over one or more media that look similar to a sponge. A fan draws air through the media and the evaporation of the water lowers the air temperature. The fan blows this cooled air through ducts into the home. Evaporative coolers work only in dry areas of the country and are most effective when the dew point is less than about 55º F.

Vented Floor Furnaces

Vented Floor Furnace Description
Vented floor furnaces provide heat to a single room or a small home with a few rooms. If they have no fan, they provide heat by natural movement of the heated air and by thermal radiation. They are most common in small seasonally occupied buildings and some rural homes. These furnaces become very hot and proper installation is important to prevent fires. Read the full Topic

Vented Room Heaters

Vented Room Heater Description
Vented room heaters provide heat to a single room or adjacent rooms. If they have no fan, they provide heat by natural movement of the heated air and by thermal radiation. They are most common in small seasonally occupied buildings, room additions, and homes in warm climates where heating demand is minimal and occasional. These heaters become very hot and proper installation is important to prevent fi res and electrical problems. Read the full Topic
