Master Your Comfort with Poolex Ice Spa

Poolex Ice Spa is a powerful heat pump and ice bath chiller designed for hot tubs, spas, and cold plunges. Distributed in Europe by TheNordicSauna, Poolex Ice Spa delivers reliable year-round performance, even in freezing conditions, and helps you elevate your spa experience to a whole new level. Elevate your spa or hot tub experience to a whole new level. We ship to all of Europe, excluding the UK.

Frost-Resistant and Energy-Efficient Full Inverter Technology
What sets the Poolex Ice Spa apart is its frost resistance down to -25°C and its highly efficient full inverter solution. The full inverter heat pump continuously adjusts the compressor and fan speeds based on heat demand, making it even more energy-efficient. Our real-life tests with our NordicSix hot tub showed that in August, with an average outdoor temperature of 17°C, the consumption was only 0.083 kW/h. Given an electricity price of 22 cents per kWh, maintaining the water at 39°C around the clock would cost just 13.2€ per month. This figure reflects 24/7 heating at the maximum temperature of 39°C. Costs can be further reduced by keeping the water at the same level as the outdoor temperature when not in use.

Versatile Compatibility
The IceSpa heat pump is compatible with all spas and hot tubs and can be easily integrated with existing wood-burning stoves or electric heating systems. For example, you can keep your current wood stove or heater for faster heating when needed. Two external relays are included in the box — when connected, they allow app-based control of your electric heater or circulation pump.

Discover the Power of Poolex Ice Spa Reversible Function

Our Poolstar heat pumps allow you to switch between heating and cooling modes with just one button press. You can select your preferred temperature with a few clicks on the display, and the pump will ensure that it is maintained.

This way, you can enjoy warm water during autumn and spring, and cool yourself down on hot summer days.

Cold water enthusiasts can take it a step further with the “Chiller” mode, which can cool the water down to 4°C. This allows you to turn your hot tub into an ice bath and enjoy the benefits of cold therapy. All of this is achieved with very reasonable energy consumption.

If your hot tub or ice tub doesn’t need to run in freezing conditions, consider the more affordable O’Spa model which cools water down to 3 °C.

IceSpa is capable of heating water not only during the spring, summer, and autumn periods but also in winter. If your goal is to keep water in the hot tub or spa continuously, even during the freezing winter months, this is the ideal solution. However, if you plan to heat your hot tub with a wood stove in winter and want to enjoy the convenience and energy savings of a heat pump during other seasons, the Spawer O’Spa model would be a more suitable choice for you.

Q&A

What is Poolex Ice Spa and how does it work?

Ice Spa is a powerful, inverter-based air-to-water heat pump engineered for year-round use in hot tubs and plunge pools — especially in Nordic and cold-climate conditions. It heats water up to 40°C and can also cool it down to 4°C when needed.

Thanks to its smart inverter technology, Ice Spa automatically adjusts its output to maintain your desired water temperature with high efficiency and minimal noise — no firewood, no manual switching, and no energy waste. Just set it once and enjoy perfectly regulated water, in any season.

What do I need to install and run the Ice Spa heat pump?

Poolex Ice Spa, like any air-to-water heat pump for hot tubs, does not include a circulation pump. It needs an existing system to circulate water through the unit for it to heat or cool effectively.

To set up Poolex Ice Spa properly, your tub must have:

Two hose connections (inlet and outlet) to allow water to flow through the heat pump
A filtration and circulation system to keep the water clean and in motion

If your hot tub doesn’t already have this, we’ve made it easy to upgrade:

We offer quick-connect hose fittings suitable for most tub types — including wooden, fiberglass, and plastic hot tubs
We recommend our FilterMax system — a high-efficiency filtration and circulation unit that’s compact, energy-efficient, and specifically designed for plug-and-play use with heat pumps like Poolex Ice Spa

Whether you’re building a new setup or upgrading an old one, we can supply everything you need for a complete, reliable hot tub heating system — without the complexity.

How fast does Poolex Ice Spa heat or cool water?

Heating and cooling times with Poolex Ice Spa depend on several factors: outdoor air temperature, water volume, insulation quality, hose exposure, and the starting water temperature.

For a well-insulated hot tub like our Nordic Six (approx. 1,350 liters), heating water from 10°C to 38°C typically takes around 7 to 9 hours under average spring or autumn conditions. In cold weather, Poolex Ice Spa still performs reliably, though heat-up times may extend — especially in tubs with minimal insulation or exposed plumbing.

For cold plunge tubs or ice baths (250–400 liters), heating or cooling is much quicker — often 3 to 5 times faster than with full-sized hot tubs. Cooling to 4–5°C is typically achieved overnight or within just a few hours, depending on conditions.

Thanks to its inverter technology, Poolex Ice Spa adapts its power output automatically to maintain your desired temperature with maximum efficiency and low noise.

Need faster heating?

Every Poolex Ice Spa unit includes two relays, allowing you to control an external electric heater if rapid heat-up is ever needed. It also pairs seamlessly with traditional wood-fired systems, giving you flexible options for every season and scenario.

Whether you’re managing a private spa, a rental property, or a weekend cabin, Poolex Ice Spa delivers fast, consistent performance without the hassle — making it a top-tier air source heat pump for spas and hot tubs.

How much energy does Poolex Ice Spa consume?

Compared to traditional electric heaters, Poolex Ice Spa can reduce your energy consumption by up to 75% depending on usage, climate, and insulation. While an electric heater draws constant high power (typically 3 to 6 kW) during operation, Poolex Ice Spa uses inverter technology to automatically adjust its power output and operate only as much as needed — often consuming between 0.6 and 1.5 kW in real-world use.

In real test conditions with our Nordic Six hot tub:

In Estonia, during August with an average outdoor temperature of 17°C and electricity priced at €0.22 per kWh, the monthly cost was approximately €13.
One of our clients monitored the energy consumption of the Poolex Ice Spa heat pump connected to a Nordic Six hot tub (without PUR foam insulation) throughout the 2024–2025 winter in Estonia. From 6 September to 16 April, the tub was kept constantly heated, and the total recorded electricity usage was 1001.11 kWh.
At an electricity price of €0.22 per kWh, the total cost for 7.3 months of continuous use was approximately €220.24, averaging just €30.05 per month.

For comparison, a standard electric heater running continuously to maintain the same temperature could cost over €150/month in winter conditions.

This makes Poolex Ice Spa not only a more sustainable long-term solution, but also a smart financial choice — especially if your spa is used regularly. Whether you’re replacing an electric unit or upgrading from wood-fired heating, an energy-efficient hot tub heater like Poolex Ice Spa delivers both comfort and real monthly savings.

Can Poolex Ice Spa be used all year round?

Yes, Ice Spa is built for reliable year-round operation — even in harsh Nordic winters. Designed specifically for colder climates, it performs efficiently in sub-zero temperatures and includes frost protection features that safeguard internal components.

Whether you’re heating your hot tub in the middle of winter or cooling your plunge pool in summer, Ice Spa delivers consistent performance across all seasons. It’s the ideal choice for users in Estonia, Scandinavia, and other regions where freezing temperatures are common.

How is Poolex Ice Spa different from a regular pool heat pump or chiller?

Poolex Ice Spa isn’t just a repurposed pool heater — it’s specifically designed for hot tubs and cold plunge tubs used in year-round, variable climates.

Here’s what sets it apart:
• Dual functionality: Provides both powerful heating and active cooling — most standard units offer only one
• All-season reliability: Built for Nordic conditions, with frost protection and efficient performance even below 0°C
• Smart inverter control: Adjusts output automatically to maintain your desired temperature efficiently
• Quiet operation: Designed for use in relaxation zones — low noise levels even during full operation
• No professional installation needed — connects to your hot tub and filtration system using standard 32/38 mm hoses and clamps.

Whether you’re maintaining a hot tub or preparing an ice-cold plunge, Poolex Ice Spa is a purpose-built, all-in-one inverter heat pump for spas — not a compromise.

What kind of maintenance does Poolex Ice Spa require?

Poolex Ice Spa is built for low-maintenance use in all seasons. To keep it operating efficiently, we recommend:

Checking the air intake and exhaust vents regularly to ensure nothing is blocking airflow
Occasionally rinsing the coil surfaces with clean water to remove dust or debris buildup
Inspect the condensate drainage outlet, especially in humid conditions — during cooling, the unit produces condensation, and a clogged drain could lead to water accumulation or internal corrosion. If you notice standing water, clear the outlet immediately
Draining and disconnecting the unit if it will be left unused during extreme freezing conditions — even though Ice Spa has frost protection, this is a smart precaution for remote cabins or seasonal use

With just basic airflow checks and simple seasonal care, Ice Spa will deliver consistent, reliable performance year-round.

Is it safe to install the Poolex Ice Spa near water?

Yes. Poolex Ice Spa is specifically designed for outdoor use with hot tubs, plunge tubs, and cold pools, where exposure to water and moisture is common.

It features a built-in RCD (residual current device) for electrical safety in wet environments, along with a durable, weather-resistant enclosure for year-round reliability.

To ensure safe operation:

Place the unit on a stable, level surface with proper drainage
Follow all installation steps in the user manual carefully
Make sure any electrical work is carried out in accordance with local regulations

When installed as instructed, Ice Spa is a safe and dependable heat pump for use near water.

Do I need a specialist to install the Poolex Ice Spa?

No. Poolex Ice Spa is designed for straightforward installation and includes standard hose connectors (32/38 mm) along with clear setup instructions. If your hot tub or plunge tub already has two water outlets for circulation, the installation process typically takes less than 15 minutes.

If your tub does not have a built-in filtration or heating system (and therefore lacks hose fittings), you can find compatible connection kits in our e-shop. We offer solutions for connecting to tubs made of wood, plastic, fiberglass, and other materials.

Follow the instructions in the user manual carefully, and there’s no need for professional installation in most cases.

What if I only want heating or cooling — is Poolex Ice Spa still a good choice?

Absolutely. While Spawer Ice Spa offers both heating and cooling, it works just as well if you only need one function. It delivers powerful heating performance for year-round hot tub use and can also cool water down to around 4°C when needed — perfect for post-exercise recovery or summer refreshment.

Having both options in one unit ensures flexibility and future-proofing, whether you’re maintaining a warm tub through the winter or preparing a cold plunge on warmer days.

How does Poolex Ice Spa enhance the overall spa experience?

Spawer Ice Spa brings consistency, control, and all-season comfort to your spa routine. Whether you’re stepping into a perfectly warm tub on a freezing winter evening or preparing a cold plunge for recovery after training, Spawer Ice Spa keeps the water exactly where you want it — automatically.

Think of it as a quiet personal assistant who makes sure your hot tub is always ready — no asking, no waiting. And if you’ve ever used a hot tub in winter, you know there’s nothing worse than getting out wet and half-frozen just to start a new fire to boost the temperature. Ice Spa takes that frustration out of the equation and makes sure the experience stays relaxing from start to finish.

Testimonials

I use the hot tub at my accommodation, where it’s heated approximately 100-150 times a year. Despite the intensive use, there’s little wear and tear. I’m very satisfied with the product; I like its compactness due to the integrated stove. This stove placement allows the water to heat up quickly. I definitely recommend adding LED lighting, which creates a special experience on dim evenings.

I recently purchased a Nordic Dome for our garden. I couldn’t be more satisfied with this investment. It has provided us with a perfect shelter where my family and I can relax and enjoy the outdoors, even when it’s windy outside. One of my favorite things about the dome is the opportunity to have dinners in it while it’s raining. It adds a special ambiance and makes the experience truly memorable. The Nordic Dome has become a cherished addition to our garden, allowing us to create wonderful memories and enjoy the beauty of nature, no matter the weather.

As the owner of a unique holiday accommodation housed in a building more than 300 years old, the addition of a hot tub has been a game-changer. Our guests adore the private hot tub, which offers them a blissful experience beneath the enchanting northern sky. Set against the backdrop of our historic property, it has become a beloved retreat, allowing our guests to unwind and soak in the beauty of the night sky. The combination of our two distinct holiday experiences, along with the inclusion of the hot tub, has elevated our place to a whole new level.
