Do You have a cold Basement?

Do you have a finished basement or basement suite that has a forced air heating system and the area is still cold?

Assuming that the finished area is insulated one of the biggest issues with forced air systems is the lack of a cold air return in these areas.

Typically a homeowner will finish off the basement or add a basement suite without the full understanding of a how the heating system works. In the majority of cases the heating registers are also located in the ceiling. The best location for heat registers is at the lower level of the finished wall with a cold air return on the opposite side of the heat source.

A forced air system relies on air movement and circulation. Most houses are designed with inadequate cold air returns. As a result, there is not enough airflow through the furnace. Additional cold air returns in the living areas, particularly in the bedrooms, can increase air circulation and heating system efficiency while improving comfort and air quality in the house.

To allow for air movement in bedrooms a minimum of ¾ inch gap is required under the door. The cold air return should also be unobstructed to allow for full airflow. Typically the cold air return register has to match the equivalent of all heating registers. ie if the total area of heating registers is 120 sq inches (6, 5 inch supply vents) then the cold air return should be 120 sq inches.(14.5 inches, inside dimension of stud framing x8.5 inches high). This will allow correct air flow.

For even heat distribution the system may also require balancing. This is typically done with the adjustment of heating dampers, which are located on some of the heat supply ducts or trunks.

By contacting a heating specialist they will be able to evaluate the entire system for you. An upgrade on the furnace is usually not required if the whole system is working efficiently

With winter just around the corner it may be time to look at the heating system in your home.
