What is the right wattage to heat my space?

Patio heaters' heat output is often measured in terms of BTUs or watts. You may encounter a product that is configurable in terms of wattage. The product you should choose for your living space will depend on a number of variables.

The size of the space you are trying to heat is one of the biggest factors in choosing your wattage. Heating larger spaces will require a more powerful unit. A good rule of thumb to use when choosing a patio heater is this simple formula:

size of space in cubic feet x 10 = number of watts you will need

Another important factor to consider is how many heaters you would like to purchase. Some people prefer to have two or more slightly less powerful units scattered throughout the space to spread the warmth more evenly, and allow for individual operation and control.

The height of your patio heater (or the height you choose for your wall-mount heater) will also influence how much of the heat will reach your living space in a concentrated amount. The higher the unit, the more your heat will disperse before it reaches the ground. The lower the unit, the more concentrated the heat will be. If you know you will be mounting your wall-mount heater to the ceiling of your 10ft pergola, you may want to go for a slightly higher wattage.
