Advanced, energy-efficient spa heating built for performance, durability, and year-round savings.
Keeping your hot tub at the perfect temperature shouldn’t cost the earth — literally or financially. The spanet Eco Cube is a high-performance inverter heat pump that offers a smarter, more sustainable way to heat your spa, with industry-leading efficiency and whisper-quiet operation.
Whether you’re using your spa daily or occasionally, this technology ensures you always have warm, inviting water with minimal energy use.
Unlike traditional electric heaters, the EcoCube draws heat from the surrounding air, working more efficiently even in lower UK temperatures.
Here’s what makes it stand out:
Up to 75% energy savings compared to standard spa heaters
Frost protection & winter-ready for year-round performance
Eco-friendly R32 refrigerant for reduced environmental impact
The UK climate demands heating systems that can cope with cold spells, dampness, and fluctuating outdoor conditions. The EcoCube is engineered specifically for this — offering reliable warmth, even in winter.
What UK users appreciate:
Rain or shine, the EcoCube delivers heat you can count on.
What sets EcoCube apart is how quietly it works. Thanks to its variable-speed fan and brushless DC motor, you’ll barely hear it running — even while it’s saving you money.
Ideal for homes where noise is a concern
Doesn’t interrupt peaceful spa sessions
Uses far less electricity than electric-only systems
Read how UK spa owners are enjoying warmer water, lower bills, and quieter nights with SpaNET EcoCube technology.
