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.Know More
Blocked air ducts or air leaks can be the culprit, particularly if most of the house has heat but one room remains cold. Rodents and insects build nests in warm passages and block air circulation throughout the home. Over time connections deteriorate, and this allows the warm air from the furnace to leak into unfinished spaces of the home. In homes with radiators, air trapped in the radiator sometimes prevents steam or hot water from moving throughout the unit, leaving one or more rooms cold.
In gas systems with a standing pilot light, the unit must burn continually. Wind gusts or back drafts down the flue sometimes extinguish the pilot light and prevent the furnace from working properly. Check the unit to ensure the pilot is lit. High efficiency systems use an electric ignition to light the pilot on demand and start the burner automatically.Learn more about Heating & Cooling
The cost of installing a central heating system depends on different factors, such as the size of the house, the complexity of the installation and the type of system installed. An average cost for either a heat pump or a gas furnace system in 2014 may be around $10,000 to $20,000, depending on the above factors.Full Answer >
Radiant floor heating involves the installation of water-heated tubing or electric heating coils under the floors in homes. The system allows the heat from the floor to warm everything it comes in contact with and radiates throughout the whole room from the ground.Full Answer >
Differential heating is the term used to explain the ways sunlight heats the Earth's zones differently depending on tilt, revolution around the sun and daily rotation. This process results in what human beings perceive as seasons and other climatic shifts.Full Answer >
Radiant heating is a heating system in which a hot object transfers heat through the air to other objects. Warmth is moved around a room through infrared radiation. The infrared radiation strikes other objects, which also radiate heat, keeping the environment warm.Full Answer >
