What is COP?
COP stands for Coefficient of Performance
COP is quoted as a number, such as 19.3
For each kW of energy input, 19.3 x kW would be output
The higher the output, the lower the running costs
Installation
The heat pumps in the Poolex Megaline Fi range are all three phase units and will require electrical installation by a qualified electrician. Full installation guidelines can be found in the user manual including the recommended fuse and cable sizes.
Water inlet and outlet connections are 63mm (Fi 35) and 75mm (Fi 50, Fi 70 and Fi 100), and come supplied with unions to accept pressure pipe.
If the flow rate through your heat pump is too high it can take longer to heat your pool or you may struggle to achieve your desired temperature, our bypass kit for above ground pools optimises the flow rate to maximise the heat transfer to your pool water. A bypass kit also allows the circulation and filtering of pool water without heating and for winterising your heat pump.
The Megaline Fi features built-in Wi-Fi connectivity as standard (requires Wi-Fi network with suitable signal strength) and can be controlled from your smart device from anywhere in the world. The Smart Life App is available for both iOS and Android smart devices.
The Smart Life App can be used to view the current pool water temperature, adjust the desired temperature, switch between modes, set the timer, turn the heat pump on and off remotely and to view the operating status, parameters and error codes.
Inverter heat pumps use a variable speed compressor motor, the motor speeds up and slows down as needed to achieve and maintain the required temperature, the result is that the desired temperature will be reached more quickly and maintained more efficiently than a fixed speed motor.
Fixed speed motors reach the desired temperature more slowly as the output is fixed, once the temperature is reached they maintain the temperature by switching the motor on and off. By varying the output an inverter heat pump can speed up the time taken to achieve the initial temperature and thereafter maintain a constant temperature without the need to keep stopping and starting the compressor to control output.
Inverter technology avoids the power wastage of fixed speed motors, making an inverter heat pump more energy efficient and quieter to run.
