BTU is an abbreviation for British Thermal Unit, which is the international measure of energy. An air conditioner's BTU must be matched to the size of the room for adequate cooling. BTU tables estimate different energy requirements.
A:A typical ceiling fan uses 60 to 75 watts of energy per hour even when running on high. This makes ceiling fans a very efficient alternative to a typical central air conditioning unit, which uses 3,500 watts.
A:First, use a voltage regulator to determine if the problem is coming from the circuitry or resistors or the heating coil. Once the problem area has been pinpointed, replace the damaged components, and test the heater again to see if it is functioning correctly.
A:Several different issues cause a central heating system to stop working. For instance, when the power is out, most systems no longer provide heat. Even though a forced air system uses natural gas as fuel, it may require electricity to operate the blower. If too many lights and electronics are on in the house, power overload can trip the electrical circuit breakers and affect the central heating system.
A:Reset procedures vary widely depending on the model of the Honeywell thermostat, but they include pressing System to reconfigure the settings or temporarily inserting the batteries backwards. Call the Honeywell technical support line or refer to the thermostat's manual for exact reset instruction for a particular model.
A:Fans do not typically cause the temperature in a room to drop. It is possible to use a fan to create a wind-chill cooling effect under certain circumstances. A person without air conditioning may only circulate hot air when setting a fan in the center of a warm room.
A:Generally speaking, thermostats work by using a mercury switch that is in contact with a thermometer wire to trigger a temperature-adjustment lever in response to the expansion or contraction of the wires as they are heated or cooled. The expansion and contraction of these wires triggers switch relays that control heating and cooling by triggering either a circulation fan and heater or air conditioner.
A:Kerosene and diesel are made up of long, flammable hydrocarbon molecules derived from crude oil, which is also known as petroleum. Kerosene is made up of a mixture of carbon chains with between six and 16 carbon atoms per chain. Diesel fuels are heavier, with anywhere from eight to 21 carbon atoms per chain. Both are liquid at room temperature, but diesel fuel has a higher boiling point.
A:A variety of external elements can cause a false alarm from a standard ionization smoke detector. Loss of power, humidity, dust, insects and debris from common household appliances can all cause a false alarm.
A:The exact method depends on the thermostat, but most programmable thermostats have a reset switch or button. This is often located below the main panel of the thermostat or on the side where it is difficult to press by accident.
A:Use the area of a room to determine the proper air conditioner size estimate, which is measured in British thermal units per hour. A 100- to 150-square-foot room needs a 5,000 BTU per hour unit, while a 400- to 450-square-foot room needs a 10,000 BTU per hour unit.
A:Repair a swamp cooler by replacing defective parts, such as blower motors, floats, pumps and evaporative pads. In areas where swamp coolers are common, most home improvement stores carry these parts. Swamp coolers are simple cooling devices and most owners can make repairs easily.
A:According to the U.S. government's Energy Star website, about half a home's energy bill goes to heating and cooling, so one way to cut down on electric bills is to ensure heating and cooling equipment work efficiently and to seal the house to avoid temperature leakage. Other ways to cut down on electricity include using hot water sparingly, upgrading to energy-efficient appliances and turning off lights when not in use.
A:Conserving non-renewable fossil fuels by utilizing the earth's natural, renewable resources is one of the major advantages of alternative energy use. Using renewable energy sources is cost effective as well as environmentally friendly.
A:A good temperature to set the thermostat to during the summertime is 78 degrees Fahrenheit. It is recommended that electricity consumers set the thermostat temperature to 85 degrees when they are away from home.
A:As of 2014, a building owner can expect to pay between $5,000 and $11,000 to replace the residential HVAC system. The cost of replacing an HVAC system varies greatly. The type of system, installation costs and any necessary changes or modifications to the structure can dramatically affect the cost of replacing the HVAC system.
A:To repair a Frigidaire dehumidifier, first identify the actual problem, and then clean or replace the affected part. Common problems with Frigidaire dehumidifiers include incorrectly set humidistats, defective fan motors and dirty condenser coils.
A:Determining the appropriate size for an air conditioner ensures proper and effective function. If the unit is too large, it cools the room but doesn't properly remove humidity, resulting in a damp or clammy feeling. Conversely, a unit that is too small doesn't sufficiently cool the room.
