Overview

The compact Poolex O’Spa 5kW heat pump can be installed on any hot tub, spa or Nordic bath, saving up to 75% in energy compared to standard electric heaters. This versatile 3-in-1 unit provides efficient heating, cooling and chilling, down to 5°C, with the ability to control your spa’s existing built-in heater for optimal temperature management.

Additionally, the unit features built-in Wi-Fi, allowing you to easily manage temperatures and program timers remotely via a dedicated iOS and Android app.

Highlights

Up to 5kW of heat output at air 26°C and water 26°C, 3.3kW of heat at air 15°C and water 38°C and 1.8kW of output at air 15°C and water 5°C

Reversible hot/cold for ultimate flexibility, heating from 10-40°C and cooling from 5-28°C with Chiller function, operates down to -7°C, with automatic defrost

Integrated control of the spa / hot tub heater with supplied 230v relay

Supplied with RCD mains cable, anti-vibration pads, 32/38mm hose tails and 2 x hose clips

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.
