12kW SV Series Heat Pump

Do you want to keep your spa warm and ready all year — without huge power bills? Then the 12kW SV Series Heat Pump is the answer. It’s the largest spa heat pump in SpaNET’s SV Series range. So it’s built for large swim spas and spa pools of 6,000L and up. Above all, it heats your spa water far more efficiently than a standard electric element. In short, it delivers powerful, all-season spa comfort at a fraction of the running cost.

The efficiency is the headline. For example, it delivers a massive 12.0kW of heating output. Yet it draws only around 2.2kW of input power. As a result, it generates most of that heat essentially for free, by drawing warmth from the air. So you can cut your spa heating costs by up to 75% — and keep your spa hot and ready to use 24/7.

How a Spa Heat Pump Saves You Money

The science is simple but powerful. A standard electric heater turns 1kW of electricity into just 1kW of heat. A heat pump, by contrast, uses that 1kW to move several kilowatts of heat out of the air. So for every kilowatt it draws, it delivers several kilowatts of warmth. As a result, most of your spa’s heat comes free from the surrounding air. In practice, that means dramatically smaller power bills — and a payback period far shorter than many other energy upgrades.

H2: Heats in Winter, Cools in Summer

This heat pump isn’t just for cold months. For example, in winter it warms your spa quickly and holds the temperature you set. In summer, though, it can reverse the cycle and cool the water instead. So on hot days, when a spa can get uncomfortably warm, you can bring the temperature back down. As a result, your spa stays perfectly comfortable across every season. Simply set your target temperature (anywhere from 10°C to 40°C) and let the heat pump do the rest.

H2: Important — SV Series Compatibility

This is the key thing to know before you buy. The SV Series heat pump is designed to work only with a SpaNET SV Series spa controller. So it connects directly to that controller via a plug-n-play cable, and the controller automatically manages heating and cooling. As a result, it’s the perfect upgrade if you already have (or are installing) a SpaNET SV-equipped spa. However, it is not a standalone heater, and it won’t heat a room, greenhouse or pool that isn’t running an SV Series control. So please confirm your spa uses a SpaNET SV controller before ordering.

H2: Which SV Series Heat Pump? 5.5kW / 8.8kW / 12.0kW

SpaNET makes the SV heat pump in three sizes, so match it to your spa. The 5.5kW model suits spas up to around 2,500L. The 8.8kW model suits swim spas and larger pools (around 2,500–6,000L). The 12.0kW model, this one, is the most powerful — built for large swim spas and spa pools of 6,000L and above. So choose based on your spa’s water volume. Not sure? Then talk to our team for help.

H2: Why Choose a Heat Pump for Your Spa

A heat pump is the smart way to run a spa. To start, it slashes running costs, so you can leave your spa hot and ready whenever you want it. In addition, it heats roughly twice as fast as a standard 3kW spa element, cutting your heat-up and recovery times. Plus, it heats and cools, so your spa suits every season. Better still, it uses environmentally friendlier R410A refrigerant and a tough, weatherproof enclosure. As a result, you get lower bills, faster heating and year-round comfort.
