Setup & Advice
Electrical
All models are fitted with a mains cable and a European two-pin RCD plug as standard.
Water inlet and outlet connections are 32/38mm, two 32/38mm hose tails are supplied as standard, however you may require additional hose and fittings to connect to your spa or hot tub. The O’Spa should be connected after your spa’s circulation pump and heater, the use of a bypass kit (normally made up of 2 x T-pieces and 3 x ball valves) is recommended to connect the O’Spa.
Supplied with RCD mains cable, anti-vibration pads, 2 x 32/38mm hose tails, 2 x hose clips and 230v relay
Wi-Fi
The O’Spa heat pump features built-in Wi-Fi connectivity as standard (requires Wi-Fi network with suitable signal strength) and can be controlled from your smartphone. The ‘Smart Life’ App is available for both iOS and Android smartphones.
Positioning
Your Poolex O’Spa heat pump should always be installed outside, restrictions on air flow around a heat pump such as dense vegetation or solid surfaces such as sheds, fences or walls will lead to a drop in efficiency and heating ability, it especially important that cooled air can be properly dispersed away from the unit.
While the casing provides protection from the weather, the O’Spa should be disconnected and stored in a shed or garage if not in use for extended periods.
The Poolex O’Spa comes with a Return to Base warranty package:
2 Year full warranty
5 Year parts warranty on the compressor
10 Year parts warranty on the titanium heat exchanger
Parts only after year 2, warranty covers manufacturing defects only
Important: Damage caused by frost is not covered by the warranty, please make sure you correctly winterise your heat pump and drain all residual water during periods of non-usage
What is COP?
COP stands for Coefficient of Performance. Simply put, it is a ratio that tells you how much heat you return to your pool for every unit of electricity you pay for.
How it Works
If a heat pump has a COP of 5.0 it means: input 1kW of electricity, output 5kW of heat, you are essentially getting 4kW of free heat extracted from the ambient air.
Why Air Temperature Matters
Heat pumps are aerothermal, meaning they pull heat from the surrounding air, because of this, the COP changes based on the weather.
Warm weather (e.g. >24°C), the air is full of heat energy, making it easy for the pump to achieve a high COP (like 5.0 or higher).
Cooler weather (e.g. <15°C), there is less heat available in the air. The pump has to work harder, which lowers the COP and reduces the total heat returned to your pool.
Expert Tip: When choosing a heat pump, don't just look at it's maximum COP, consider the air temperatures during your specific swimming season. A pump that is powerful enough for July might struggle in May or September.
You can refer to our Heat Pump Sizing Guide to ensure you select the correct capacity for your pool size and desired swimming season.
