During winter time, people frost from cold and seek to find heat. During pre-industrial revolution, people uses fireplace exhausted through a smoke stack or chimney to provide heat and comfort through homes during extreme cold. By the emergence of technology and digital age, heating systems have developed exhibiting different designs,types, and functions. It has also been incorporated through HVAC systems that are efficiently use all year round.
This page will explain the importance of heating systems, how it works, and what to do when the heating system isn’t working well–might as well when to self- repair it or when to seek a professional help.
What is a Heating System?
-mechanism of maintaining the temperature of a space through supplying heat to the room involved. It is often incorporated in HVAC system.
Types of Heating Systems
-this works by blowing heated air through ducts that deliver the warm air to rooms throughout the house via air registers or grills.This type of heating system can be powered by fuel oil, electricity, or natural gas.Also, this heating system are most widely used by people because of it’s convenience and efficiency.
-The furnace works through the mixture of air and fuel oil then, burned.The flames heat a metal heat exchanger where the heat is transferred to air. Air is pushed through the heat exchanger by the “air handler’s” furnace fan and then forced through the ductwork downstream of the heat exchanger. At the furnace, combustion products are vented out of the building through a flue pipe.
-these are special purpose water heaters. While furnaces carry heat in warm air, boiler systems distribute the heat in hot water, which gives up heat as it passes through radiators or other devices in rooms throughout the house. The cooler water then returns to the boiler to be reheated. This topic would be further discussed on a separate page for water heaters.
c. Heat Pumps
-these are two way air conditioners.During summer, an air conditioner works by moving heat from the relatively cool indoors to the relatively warm outside. In winter, the heat pump reverses this trick, scavenging heat from the cold outdoors with the help of an electrical system, and discharging that heat inside the house. Almost all heat pumps use forced warm-air delivery systems to move heated air throughout the house.
Common Problems with Heating Systems
There are multiple reasons on why heating systems malfunctioned. One should realized that like any other technology, it should also be taken care of to avoid any damage among it’s parts. The list below are the following common problems that most people complain about heating systems;
a.Lack of maintenance
-the heating system should be regularly cleaned and checked to avoid clogging and accumulation of dirt. If one neglects this, it should experienced unexpected breakdowns and an increase in energy cost.
b. Dirty or clogged filters
-one should replace the filters monthly to assure efficiency of the heating system.
c.Mechanical wear and tear
-any leakage or tear of coils,wires or any mechanical parts could cause problems with heating system functioning. It could overheat or under heat that will compromise the performance of the heating system.
d.Pilot or Ignition control problems
-malfunctioning or not releasing heat is a sign also of ignition control defect. There are typically two types of ignition control: 1.Hot Surface Ignition 2.Intermittent Pilot.
-A thermostat is a device that controls how much heat that should be produced. Problems with heating systems could result in no heat,no fan to force the hot air through your home, or intermittent heat which result in comfort problems.
Fixing and Taking care of Heating Systems
Heating systems could be fixed manually if the problem is not severe and could be handled easily. But if could not be handled, one should seek a professional technician to solve it.
But instead, one should note on how to take care of these heating systems in order to preserve and prolong it’s lifespan not risking to get any help.Below are some ways on maintaining heating systems quality;
a.Check the filter(s) once a month and replace as necessary. Homes with pets or residents with asthma should check even more frequently. A rule of thumb is to check every month and change at least every three.
b.Have ductwork checked at least once a year for open joints, dust buildup, mold and rust. Open joints should be resealed with duct tape. Corroded ducts will be repaired or replaced.
c.Clean ductwork and registers as needed. Where there are no obvious problems, having ducts cleaned by a professional once every three years may be adequate. In dusty environments or those where occupants have pets or suffer from allergies, more frequent cleaning may prove beneficial.
d.Clean dust and soot from the furnace combustion chamber. Your technician will check this chamber as part of their periodic checkup. He’ll ensure that electricity and gas to the unit is turned off, and after inspecting the chamber, he’ll clean it.
e.Clean the blower. This is a procedure in which the HVAC technician will vacuum out the area where the blower is housed.
f.Inspect the blower belt (if present). Many furnaces have direct-drive blowers, but if your technician encounters a drive belt as they clean, he will inspect it for proper tension and overall condition.
g.Have water temperature and pressure checked. Once the system has been running for an hour or so, have the temperature and pressure gauge checked. The water temperature should be within the range of 180⁰F and 200⁰F. Pressure within the system should be between 12 PSI and 25 PSI—for a two-story house, 18 PSI is all that’s needed. If the temperature or pressure measurement falls outside these specified ranges, consult a technician.
h. Have the circulating pump lubricated. If it has lubrication cups, a few drops of 3-in-1 oil will be squirted into them.
i. Clean soot from the inside of the boiler’s combustion chamber. This periodic checkup is part of your technician’s regular maintenance and is similar to cleaning the chamber in a forced-air system, including cleaning with a wire brush and vacuuming.
j. Dust radiator surfaces and straighten fins on baseboard heaters. All that’s needed is a vacuum. If fins are badly bent, a professional may use a fin comb to straighten them.
k. Get air purged from the radiators. The bleeder valve on each baseboard run or radiator will be opened. The valve will be left open until water begins to trickle out, then it will be closed.
l.Drain and flush the system. Most experts recommend having a professional do this once every five years at minimum.
