How Heat Can Escape Your House and How You Can Prevent It

As the cold season approaches, energy bill goes up. This is mainly because of the need for heating systems on winter months. But not all the heat generated by your heating device stays in your house. Some, or in certain occasions, most of them escape from your house. As a result, your heating device has to work harder resulting in unwanted increase in energy consumption and cost.

This can be avoided by effectively seeking out the root cause of the problem, and dealing with them accordingly. Follow these simple do-it-yourself methods and save hundreds or perhaps even thousands of dollars on energy cost.

Doors and windows

Doors and windows usually have gaps and spaces on them where heat can escape. Although they may not be that much, if you consider how many doors and windows there are in your house, they collectively result in a huge loss which will reflect badly on you next month’s energy bill. A simple remedy to this problem is covering the gaps with curtains, drapes and/or sheets. You can also use rugs and door sweeps to cover the gap beneath your door.

Electrical and cable ducts

Electrical wires, telephone wires and internet cables and others of the like enter your house through holes and/or ducts. And through these channels, heat can escape. You can easily remedy this by installing outlet gaskets or stuffing the holes and ducts with certain materials such as foam.

Cracks, gaps and leaks

First, you need to find where they are, but looking for them just by sight can be very tricky. You can use a lighted candle and move it near suspect places. The flame of a candle is sensitive to airflow and will sway at the minutest air movement. When you see the flame swaying at a certain spot, there must be an air leak there. Once you have found the cracks, you can seal them by using a caulk. But make sure to apply it both on the inside and the outside.

Attic and ceiling.

A popular physics law states that “hot air goes up”. This is also true inside your house. The heat produced by your heater is likely to accumulate on the ceiling and you attic. This will only result in wasted energy because people don’t normally stay on those places. You can prevent this by making sure that the gaps and cracks to your ceiling and attic are sealed. You may want to check your folding attic stairs if you are using one. You can use weatherstripping and caulk to remedy the problem.

Heat only certain areas

You may ask yourself: “do you really need to heat the entire house?” Maybe there are areas in your house that are not frequented by people and do not need to be heated. If you can manage to limit the range of your heater only to places that are frequented by people, and avoid places such as hallways, storage rooms, attic, and others of the like, you can definitely cut down on your energy consumption cost.
