Experience unmatched efficiency and comfort with EVOAQ's advanced home heat transfer systems
How a fireplace heat transfer system works
A wood fireplace can produce more heat than is needed in the room where the fire is located. EVOAQ uses that excess heat to warm other rooms in your home.
The process is simple: the fireplace heats the lounge, warm room air is collected, an EC fan moves the air through ducting, and the warm air is delivered to bedrooms and other rooms.
Unlike a conventional three-speed fan, the EVOAQ EC fan continuously adjusts its speed to match the heat available from the fireplace. This lets the system make use of available heat without simply switching between fixed fan speeds.
Intelligent, variable-speed heat transfer
The wall controller displays the room temperature and the homeowner's selected comfort level. Heat transfer can start when the room is warmer than that selected level. For example, if the comfort level is 22°C and the room is 23°C, the system can begin transferring heat.
The fan then manages the amount of heat being transferred. Its embedded controller and temperature sensor continually monitor the available heat and adjust the EC fan speed smoothly. As the fireplace produces more heat, the fan can increase airflow; as the available heat falls, the fan slows down.
The homeowner can set the maximum operating level to 30%, 60% or 100%. Within that limit, the fan can continuously vary its speed from 10% upward rather than repeatedly switching between three fixed speeds.
Why Heat Transfer Works So Well with Wood Fireplaces
Wood fireplaces are particularly well suited to heat transfer because their heat output is not as tightly controlled as a heat pump. At times, the fireplace produces more heat than the lounge needs.
Instead of leaving that excess heat in the fireplace room, EVOAQ transfers warm room air to other parts of the home. The system responds to the heat that is actually available, so the fan does not need to operate at one fixed speed.
