With Mitsubishi Electric’s Zuba-Central technology, savings are easy to realize. Any heating & cooling system’s performance is represented by its COP (coefficient of performance), which is a standard measurement of how much energy is gained from each unit of fuel input.

This chart shows a COP comparison between Zuba-Central and electric resistant heaters and gas furnaces:


In Canada, the 3 most common heating systems are electric, gas and oil. Any system that works with a COP of less than 1 costs you more than it’s worth in terms of lost energy. A number lower than 1 simply means you’re putting more energy into your furnace than what you’re getting out.

Generally, there are 3 types of gas furnaces. They are low, mid or high efficiency. The COP of old, low-efficiency gas furnaces (no longer available in Canada) is lower than 0.75. The COP for a mid-efficiency gas furnace ranges from 0.78 to 0.82. Even gas furnaces with the highest efficiency can only achieve a COP from 0.89 to 0.95. Oil furnaces are typically less efficient with a COP of 0.60 to 0.80.

In contrast, a baseboard heater or an electric resistance furnace is more efficient than a traditional oil or gas furnace because it has a COP equivalent to 1. So 100 percent of energy going in is converted to heat.

Now, with Zuba-Central furnaces, you get what you pay for – and more. The COP ranges from 1.4 – 3.19! These amazing ratings are achieved because not only does it convert 100 percent of all energy to heat, but it also absorbs outdoor heat energy, which is essentially free.
