A Guide to Energy Efficient Heating
An average household in the U.S. spends above $2000 yearly on their energy bills. Almost half of that amount are heating and cooling costs. The average energy expenditure of an average household is twice as much as the greenhouse gas emissions of an average car. By choosing the right heating option you can save on energy costs, improve the comfort level at home, and help fight against global warming. By choosing the right heating system and incorporating efficient operation, you can get your heating bills down by 30 percent. The tips below will help you keep the heating in your house on budget and energy efficient.
Choose the appropriate type of heating. Depending on certain factors your might benefit more by using a certain type of space heater.
One of the most popular heating options are electric heaters. They are suitable for you if you need to heat a small area or an area that does not require constant heating. They are usually quite small, which makes it easy to move them around the room or between different rooms of the house. So if you have a small room or will be fine with just sitting in front of the heater (if you choose a smaller electric space heater), this will be the best energy efficient option.
Also, for small and medium sized areas you can consider a gas heater. If you will have the heater running all day, then choosing a gas heater can be a cheaper and more efficient option. However, gas prices are on the rise and many homes have solar power which makes electricity much cheaper.
Look for a heater that has an adjustable thermostat. So you can set the desired temperature and in order to save energy the thermostat will regulate the heater operation. Once it reaches the set temperature, the heater will start cycling off and on to keep the temperature at that level. This eliminated inefficient operation and waste of energy.
Some of the space heaters offer an energy saving mode that provides maximum heat transfer rate. After you set the desired temperature, the space heater programs itself for operation with the appropriate power level, taking into consideration both the temperature you set and the temperature of the room.
Some people prefer oil filled heaters as they still retain some of the heat after shut off. So you can warm up the room to a comfortable level and then lower the setting and you will still be getting enough convection warmth from the heater.
Its also important to use the thermostat correctly. Setting it to about 18-20 degrees for a living area should be enough. If you want tropical temperatures in the room, even increasing the temperature by just several degrees can lead to an increase of your energy bill to as much as 10 percent. Keep your thermostat protected from draughts, direct sunlight and heating outlets. Its not advisable to keep the thermostat on external walls.
When you go out turn the heater off. Its cheaper to turn it on when you return. Also, you can turn the heater off overnight while you sleep. Look for a heater that comes with a timer or you can install one yourself. You can use it to turn the heater on and off automatically. For example, you can program it to turn the heater on 20 or 30 minutes before you rise in the morning or half an hour before you return home in the evening.
Minimize the area that you want to be heated. While you are heating a certain room, close the doors to prevent the heat from escaping. At one time heat only the area that is currently in use.
Insufficient insulation can be the cause for your rooms being too hot or too cold. If your home doesn’t have proper air sealing and insulation, no matter how good the efficiency of your heating system is, it will not bring the temperature to a comfortable level. Or it will have to work harder to get it to that level.
Old age or poor condition can cause the heating system to work less efficiently. So its advised to follow proper maintenance of the equipment. If your heating is over 10 years old, its probably time to make a change.
