The savings are easy to see and even easier to realize with Zuba-Central. A heating and cooling system's performance can be simply represented by its Coefficient of Performance (COP). COP is a standardized measurement of how much energy you get from every unit of fuel input. The following chart shows a comparison of COP between gas furnaces, electric resistance heaters, and Zuba-Central:

How much am I really saving ?

Here's an example comparison of annual heating costs for a typical 2,500 sq.ft. house in major cities across Canada.

Estimated Annual Heating Costs (Savings) for a typical 2,500 sq. ft. house. In Vancouver, a 2,500 sq. ft. house with a gas furnace and a COP of 0.85 would spend approximately $1,633 in heating bills in one year. If this same house were equipped with a standard electric heater, one year of heating could cost you an enormous $2,571. Zuba-Central, on the other hand, would only cost about $778. Even though Zuba-Central also uses electricity, it is staggering how much more efficient it actually is. This means you would save $855, or 53%, a year on energy costs over a gas furnace, and $1,793, or 70%, over electric heaters. That's a potential savings of almost $18,000 in your pocket over 10 years.

What do all the numbers mean ?

The three most common heating systems used across Canada are gas, oil, and electric.

Gas furnaces are one of the most common heating systems used in Canada, while oil furnaces are still used in many parts of the country. However, any system that operates with a COP lower than 1 is costing you more than it’s worth in lost energy. Having a number less than 1 simply means you are not getting as much energy out of your furnace as you are putting into it.

There are generally 3 types of gas furnaces: low-, mid- or high-efficiency. Older low-efficiency gas furnaces, which are no longer available for sale in Canada, have a COP of less than 0.75. Mid-efficiency gas furnaces have a COP ranging from 0.78 to 0.82. Even the most efficient high-efficiency gas furnaces can only achieve a COP range of 0.89 to 0.95. However, oil furnaces are generally much less efficient, with a COP ranging from 0.60 to 0.80.

In comparison, electric resistance furnaces or baseboard heaters are actually more efficient than traditional gas and oil furnaces, as they have a COP equal to 1. This means that 100% of the energy going into the system in the form of electricity is being converted into heat.

Now with Zuba-Central, you get what you pay for and more, with a COP ranging from 1.4 to 3.19. Zuba-Central is able to achieve these amazing COP ratings because it not only converts 100% of all electrical energy into heat, but it also absorbs outdoor heat energy – energy that is essentially free. Zuba-Central is a heat pump with two key components: the compressor and the refrigerant. The system absorbs heat energy from outside and transfers that energy indoors via refrigerant which is moved throughout the system by the high efficiency compressor. And the higher the outdoor temperatures rise, the more efficient the system becomes. Zuba-Central is simply a better and much more efficient way to heat and cool your home all year round.
