Heating oil is the most expensive of all of the three main fuel sources for the central heating systems. Wood is possibly the cheapest source of fuel, but it is the hardest one to obtain in some areas. The most sensible source of power for the majority of locations is the mains gas supply.
If you are serious about controlling the cost of central heating then you need to do a complete check of your home for air leaks. Air can get into the home around windows and doors and when it does it causes the temperature inside the home to raise or drop. The system you have in place to control the temperature inside the structure is forced to work harder to keep you comfortable. Stopping these air leaks with inexpensive items such as new gaskets around the entranceways into the home can save you a lot of money in your heating cost.
Central heating cost can be reduced if you do regular maintenance on the appliance. You need to do a check of the filters, and all other components of the system to make sure it is functioning at its highest capacity. Dirty air filters make the unit have to work harder. When it is being forced to work harder the cost of operations is increased. So making certain that filters are clean and the air flow is unobstructed will reduce the cost of operations.
You need to set the thermostat in the building on one temperature and leave it there. If you are constantly adjusting the temperature then you are causing the unit to work harder to try and satisfy the demands you are making on it. Select a temperature where you can be comfortable and leave the thermostat in that position. If you get a chill you can always put on a sweater to drive it away instead of increasing the temperature in the room.
We are all looking for ways to reduce our monthly expenses and reducing the cost of central heating is one of the first things we can do to lower our monthly expenses.
