Poolex Spawer O'Spa Spa Heat Pump 3 kW + Cooling Function
The Poolex Spawer O'Spa 3 kW is a compact heat pump specifically developed to efficiently heat and cool spas and Nordic tubs. Instead of bringing the water to temperature solely with a conventional electric heater, the O'Spa draws a large part of the required energy from the outside air. As a result, energy consumption for heating can be up to 75% lower.
Thanks to its compact design and simple Plug & Play installation, the O'Spa can be integrated with an existing spa setup. This allows you to continue using your existing electric heater while simultaneously benefiting from the higher efficiency of a heat pump.
This version has a heating capacity of 3 kW and also features a cooling function, allowing you to not only heat your spa during colder days but also use it for cooling during hot summer days.
Heating and cooling with one device
The Poolex O'Spa is more than just a spa heat pump. The device can both increase and decrease the water temperature.
During colder periods, you use the heat pump to keep the spa water comfortably warm. In the summer, you switch to the cooling function to actively cool the water down.
The cooling mode can cool the water by approximately 3°C. This allows the spa to also be used as a cold plunge pool if desired.
Up to 75% energy savings
A traditional electric spa heater converts electrical energy directly into heat. The O'Spa operates on the heat pump principle, which also extracts heat from the ambient air.
As a result, not all heat needs to be generated directly via electricity. Under favorable conditions, the manufacturer states this can result in energy savings of up to 75% compared to conventional electric heating.
The actual savings depend on factors such as the outside temperature, desired water temperature, spa insulation, usage duration, and the quality of the spa cover.
3 kW version for compact spas
This version has a capacity of 3 kW and is particularly suitable for small to medium-sized spas and hot tubs.
For larger spas or situations where a higher heating speed is desired, the O'Spa is also available in 5 kW and 7 kW versions.
When choosing the right capacity, it is not just the volume in liters that matters. Insulation, outside temperature, and desired water temperature also have a significant impact on the required heating capacity.
Ideal for maintaining spa temperature
A heat pump works best when it does not have to reheat a completely cooled-down spa every time.
By keeping the water at a relatively constant temperature, the O'Spa can operate efficiently and the traditional electric heater needs to turn on less frequently.
A well-insulating spa cover is highly recommended for this. With an open spa, a lot of heat is lost through the water surface.
Plug & Play installation
The Poolex O'Spa has been developed to be integrated as easily as possible into an existing spa installation.
This means you do not necessarily have to completely replace the original electric heater. The heat pump can be incorporated into the system as an additional, more energy-efficient heat source.
This gives you the advantage of efficient heating with a heat pump, while the existing heater remains available whenever extra heating capacity is needed.
The exact hydraulic and electrical connection depends on the spa and the existing installation.
WiFi control
The Poolex O'Spa features WiFi control.
This allows you to control the heat pump remotely and manage the main settings via a compatible smartphone app.
This is especially convenient for a spa. For example, you can check the temperature in advance or adjust settings without having to go to the technical installation every time.
Titanium heat exchanger
The O'Spa is equipped with a titanium heat exchanger.
Titanium is excellently suited for use with pool and spa water due to its high corrosion resistance. Heat is transferred to the water via this heat exchanger.
As a result, the heat pump is designed for long-term use in a spa environment.
Compact design
Because the technical space around a spa is often limited, the O'Spa has a compact design.
The heat pump can therefore be placed relatively easily next to a spa, hot tub, or Nordic tub.
However, there must always be sufficient free space around the heat pump. The unit extracts energy from the outside air and therefore needs to be able to draw in and discharge enough air.
Therefore, do not simply place the heat pump in a completely enclosed cabinet or technical room.
For summer and winter
With the combination of heating and cooling, you can use the O'Spa across different seasons.
In colder periods, it supports heating and maintaining the temperature of the spa water. During hot summer days, the cooling machine can be used to extract heat from the water.
This gives you much more control over the desired water temperature than with a standard electric spa heater, which can only heat.
Suitable for various types of spas
The Poolex O'Spa has been developed for use with various spa and wellness installations, including:
- Fixed spas
- Acrylic spas
- Hot tubs
- Nordic tubs
- Wellness pools
- Spas with an existing electric heater
For installation, the spa must be suitable for the hydraulic connection of an external heat pump.
Comfort in every season
With the Poolex Spawer O'Spa 3 kW + Cooling Machine, you turn a spa into a more versatile wellness installation. In the colder months, you use the heat pump for efficient heating, while during hot summer days, you can switch to active cooling.
The combination of 3 kW capacity, up to 75% energy savings, WiFi control, titanium heat exchanger, Plug & Play installation, and a cooling temperature down to approximately 3°C makes the O'Spa an interesting upgrade for those who want more control over the temperature of their spa or hot tub all year round.
