# Adding a Room? Reducing Heating Costs when Expanding your Living Space

So, you’re thinking about finishing that basement or bonus room and your calculating the costs. A major expense when it comes to the finishing construction of rooms in completed homes is the heating equipment or the expansion of an existing system. It can be a real hassle, not to mention extremely costly when it comes to running duct work to the new space. Or maybe you just have a bathroom that no matter what you do, stays a little cool.

There’s actually a simple calculation that will help you determine how much heat or wattage you need from a heater to keep it at a comfy temperature.

The information you will need on hand is all available to you.
-You’ll need to know the cubic footage of the area you’d like to heat or provide supplimental heating for.
This is easily determined; multiply the width of the room by the length of the room and then multiply again by the height of the room. For example if the room is 10 x 10, with 8 foot ceilings: 10 x 10= 100,
100 x 8 =800

-You’ll need to know where you’re located for the next variable in the calculation. In colder, northern states, it is usually recommended that the variable for the amount of heat required is 1.5 watts per cubic foot. Or if you are located in the warmer, southern states, 1 watt per cubic foot is usually sufficient.

So, say you live in Florida and the bonus room is 12 x 12 with 9 foot ceilings.
