Your home can be heated in a variety of ways, as there are many different types of heating systems and technologies that are available. Some heating systems may be more efficient than others, but the problem is that they may not be suitable for use in your home. The options include boilers and furnaces, wood heaters, solar heating, and multipurpose heat pumps that are used for booth cooling and heating.
An energy efficient heating system will accomplish less if your home including the doors and window are not properly sealed and insulated, and an energy-efficient home cannot only be comfortable, but can also save you money. The major parts of the home heating systems include the furnace or boiler that supplies the heat, the ducts, radiators and piping that distributes the heat, and thermostats that are used to regulate the temperatures. In certain situations, such as when there is no distribution system, space heaters can be used as the main or supplemental heating source. Energy efficient heating systems use less energy and are Eco-friendly, and they can help to reduce the emission of greenhouse gases.
Heating your home accounts for the major part of your energy bill, and you should know what the contributions are, in order to make an informed decision if your heating system is in need of an upgrade. Your options may be limited by your current system, as well as the sources of your energy supply.
Depending on where you live, your options for home heating systems may be:-
Electricity is run through heating elements where the resistance causes heat to be generated. The heating elements may be contained in a furnace, from where the heat is distributed throughout the home via an air-circulation system, or they may be located in baseboard heater, that are installed on the bottom of the walls where it meets the floor. Depending on the load requirements of other electrical appliances, you may need to upgrade your electrical service, if you are considering installing baseboard heaters or an electric furnace, and you may need the services of a licensed electrician.
The efficiency of natural gas heating systems is noted by their Annual Fuel Utilization Efficiency or AFUE, which indicates how efficient the system is over the heating season. For example, a high efficient furnace with an AFUE of 95 % per cent will provide 95% of the natural gas energy to the home throughout the year or period in which the home is heated.
In addition to furnaces, there are boilers that create heat by boiling water, which is then distributed to other area in the home via heat exchange units. The boilers are available in different levels of efficiency. Mid efficiency boilers have AFUE of 80 – 85 %, while high efficiency boilers are rated at 90%. Estimates are that your energy bill can be reduced by as much as 35%, with a high efficiency boiler. Another alternative that is gaining popularity in several parts of Europe and Asia is the geothermal heating system. This system uses renewable heat source that is extracted from the earth, to cool a heat your home. The system can lower you heating costs by as much as 70%.
