Zuba-Central vs. Traditional Furnaces & A/C
Zuba-Central vs. Traditional Heat Pumps

Questions Answers
Is heating with electricity expensive? Zuba-Central is an energy-efficient heat pump that can be up to 319% more efficient than traditional electric furnaces and baseboard heaters. So instead of costing you more, it will cost you less to operate Zuba-Central
Did you know? Even the most efficient gas furnaces can only achieve an energy efficiency of 95%. In a typical 2,500 sq.ft. Canadian home, Zuba-Central can save up to 53% in annual heating costs over a gas furnace. Powerful Savings
The outdoor units of many energy-efficient air conditioners are getting bigger and occupying a lot of real estate. Since Zuba-Central is also energy-efficient, is its outdoor unit large as well? Compared to many energy-efficient air conditioners which need to expand in size in order to achieve high efficiency, the outdoor unit of Zuba-Central is designed with horizontal air discharge instead of the traditional vertical discharge, which is why the unit is so compact that it is only 13" deep.
Many air conditioners are noisy – you can hear them running. Their rumbling noise can be heard through windows even when they are closed. Can Zuba-Central also be heard running? The Zuba-Central outdoor unit is the quietest in the industry, with a sound level as low as 52dB. This is equivalent to the sound of mild rainfall in Spring.
Did you know? The noise level of traditional air conditioners is at least 80dB. That’s the same level as inside an arcade centre or beside a railroad when a train passes by.
My house is either too warm or too cold. How can I achieve the optimum comfortable temperature? Zuba-Central offers the optimal comfort with the intelligent VCSi technology & ECM fan motor. The capacity of the system is constantly changing in response to the actual demand of the house. Even when there it is a large house-warming party, Zuba-Central is still on the job to keep everyone cool.
Did you know? Traditional systems are only capable of providing one single capacity, regardless of demand.
It takes energy to heat and cool a house which is not environmentally friendly because it generates greenhouse gas. Is Zuba-Central energy-efficient? Since Zuba-Central is energy-efficient and its capacity varies according to demand, it is actually more eco-friendly as it contributes less carbon emissions than traditional air conditioner and gas or oil furnaces.
Traditional Heating and cooling systems require lots of maintenance. Does Zuba-Central require a lot of maintenance? Zuba-Central provides both heating and cooling within the same system, thus requires less maintenance than having one air conditioner and one furnace. In addition, Zuba-Central is electrically operated and has no ignition-related problems.

Questions Answers
Is it true that heat pumps can only provide heat to 0°C, and are often paired with a less efficient auxiliary heat such as gas furnace? Zuba-Central operates at high efficiency down to -30°C with Mitsubishi’s exclusive H2i technology. The system is electrically operated even under extreme low outdoor temperatures, high energy efficiency all year long without compromise.
Did you know? The benefits of many traditional heat pumps are lost in winter because heat pumps and furnaces cannot operate simultaneously.
Do Heat pumps provide the same comfort levels as traditional a/c and furnaces? Zuba-Central offers the ultimate comfort with the intelligent VCSi technology & ECM fan motor. The capacity of the system is constantly changing in response to the actual demand of the house.
Did you know? Only 10% of the time a system is needed to operate at maximum capacity, yet a traditional heat pump equipped with a single-speed compressor can only provide the maximum capacity all the time. That means the remaining 90% of the time your need for comfort is being ignored.
Some heat pumps on the market said to have excellent heating performance and energy efficiency. What is the difference between Zuba-Central and them? Many heat pumps are designed with a 2-stage compressor or even multiple compressors in order to save energy, What this really means is you can only save energy in a 2-tier level or you are limited to as many levels as the number of compressors used. This also means more parts need to be maintained and there is a higher chance of failure.

Zuba-Central houses only one Mitsubishi made variable-speed compressor. Mitsubishi Electric is world renowned for its compressors, which combine the utmost quality with manufacturing excellence. Just one variable-speed compressor offers more comfort levels than a 2-stage compressor or multiple compressors, with the same, or even better, heating performance and energy efficiency.
The outdoor units of many air conditioners or heat pumps can be heard running. Is the operation of Zuba-Central’ outdoor unit loud as well? Zuba-Central’s outdoor unit is the quietest in the industry producing sound levels as low as 52dB. This sound level is equivalent to that of a mild Spring rainfall. On the other hand, although some heat pumps are quieter than many traditional air conditioners, they can still be heard operating at sound levels of at least 70dB. That's a sound level equivalent to refrigerator running or hairdryer blowing.
The outdoor units of many energy-efficient air conditioners and heat pumps are getting bigger and occupying a lot of real estate. Since Zuba-Central is also energy-efficient, is its outdoor unit large as well? Compared to many energy-efficient air conditioners and heat pumps which need to expand their outdoor units in size in order to achieve high efficiency, the outdoor unit of Zuba-Central is designed with horizontal air discharge instead of the traditional vertical discharge, which is why the unit is so compact that it is only 13" deep.
Do the Zuba-Central heat pumps cause power spikes at start-up, that makes the lights dim and flicker? The compressor in a Zuba-Central system features a unique “soft start” function, which draws only a small amount of power at start-up. This eliminates light flickering and energy spikes.
Did you know? A traditional compressor draws most energy at start-up an energy spike. The more frequent a compressor starts up, the more energy you are using.
Does the Zuba-Central outdoor unit have to be installed on or near the floor? Zuba-Central’s outdoor unit is very light and weights only 267 lbs. Because it is so slim and compact, the unit is easy to handle and may also be wall-mounted to save your space.
