How Calorex Heat Pumps Work
A Calorex pool heat pump works by extracting heat from outside air. The unit draws outside air over an evaporator coil containing eco-friendly R32 refrigerant. The refrigerant absorbs the heat, passes through a compressor to significantly multiply its temperature, and then transfers this concentrated heat safely into your swimming pool water via a titanium heat exchanger.
What makes the I-PAC and V-PAC models exceptional is their Stepless Inverter Technology. Older, traditional on/off heaters draw massive power spikes to start and run at 100% capacity until the pool is warm. Calorex inverter models, however, automatically modulate their fan and compressor speeds to precisely match the pool’s changing heat demands. Once your pool reaches the target temperature, the pump slows down, maintaining the heat using only a fraction of the electricity.
Which is Right for You?
Understanding the difference between the two ranges can help you select the ideal model for your outdoor space:
- Calorex I-PAC (Side Outlet): Featuring a sleek, rust-proof aluminium alloy casing, these models blow cold exhaust air out horizontally. They come with built-in Wi-Fi as standard, allowing you to control and monitor your pool temperature from anywhere via a smartphone app.
- Calorex V-PAC (Top Outlet): Encased in a ABS shell, the V-PAC range discharges its exhaust air straight up into the sky. This makes it the perfect solution if you have limited plant room space, nearby walls, or restricted boundary lines, as the top-outlet design effectively reduces the footprint size by up to 46%.
