How KOVE Heat & Cool Chillers Work
Say goodbye to bags of supermarket ice forever. KOVE smart chillers use closed-loop compressor heat pump technology to chill water down to 3°C or warm it up to 42°C, keeping your water crystal clear, sanitized, and ready on demand.
Dual Heat & Cool Compressor
Powered by high-efficiency rotary compressors with low-GWP R32 eco refrigerant. Unlike cooling-only units, KOVE chillers reverse cycle smoothly to heat your tub up to 42°C during chilly British winter nights.
Rapid Pull-Down Performance
Engineered with titanium heat exchangers that resist corrosion while accelerating thermal transfer. Water pulls down rapidly from ambient summer temperatures to freezing sub-5°C without stalling.
Continuous UV + Ozone Sanitation
Dual-stage chemical-free purification: integrated ultraviolet-C light eliminates microbes at the cellular level while the internal ozone generator neutralises organic matter and odour, drastically reducing chemical reliance.
Built-in Self-Priming Water Pump
No external water pumps or tedious manual siphon priming required. The internal heavy-duty circulation pump draws water automatically through the closed circuit at a whisper-quiet operating volume.
20-Micron Micro Filtration
Housing high-density 20-micron pleated filter cartridges that trap hair, dead skin cells, garden pollen, and airborne grit. Washable and easy to swap in seconds with UK-stocked replacement 5-packs.
iOS & Android Smart WiFi Control
Schedule chill cycles to take advantage of cheaper off-peak electric tariffs (e.g. Octopus Energy). Turn the chiller on while driving home from the gym or setting up for an invigorating morning routine.
Universal 1/2-Inch Quick-Connect Compatibility
Every KOVE chiller comes fitted with commercial-grade 1/2″ quick-release push fittings and food-grade reinforced hoses. Connect directly to KOVE Essentials, Core, Elite, and Pro tubs, or retrofit to any existing ice plunge with standard 1/2″ water ports in under 5 minutes without tools.
Indoor Infrared vs. Outdoor Traditional Saunas
Choosing between an indoor infrared cabin and a traditional outdoor Harvia-heated sauna depends on your available space, preferred heat intensity, and electrical setup. Here is how they compare:
Full-Spectrum Infrared Cabins
Gentle radiant heat waves that penetrate deeply into muscles and joints at comfortable, breathable temperatures.
- Operating Temperature 45°C – 65°C (Gentle, breathable radiant heat)
- Timber Material Canadian Hemlock (Hypoallergenic, resin-free & knot-free)
- Electrical Requirements Standard UK 13A household 3-pin plug (Plug & Play)
- Heat-Up Time 10 – 15 minutes (Quick & convenient daily use)
- Best Placement Spare room, home gym, large bathroom, or garage
- Typical Running Cost Approx. 40p – 60p per 30-minute session
Outdoor Cube & Barrel Saunas
Authentic Nordic high-temperature sauna ritual powered by volcanic rock heaters with invigorating steam bursts (löyly).
- Operating Temperature 75°C – 95°C (High ambient heat + steam löyly)
- Timber Material Canadian Spruce with weatherproof bitumen shingles
- Electrical Requirements 4.5kW – 8kW Harvia heater (Part P UK Electrician 32A connection)
- Heat-Up Time 30 – 45 minutes
- Base Requirements Solid level base (concrete pad, paving slabs, or reinforced deck)
- Typical Running Cost Approx. £1.20 – £1.80 per session
Electrical Supply Planning
Our 1, 2, and 3-person indoor infrared saunas plug straight into a standard 13A wall socket. Outdoor cube and barrel saunas with 4.5kW–8kW Harvia heaters require an outdoor rotary isolator switch installed by a qualified Part P registered UK electrician.
Ground & Base Preparation
Outdoor saunas and high-capacity plunge tubs must be placed on a completely flat, level, load-bearing foundation—such as a concrete pad, solid paving flags, or reinforced structural timber decking.
Contrast Therapy Routine
Combine a 15–20 minute sauna session with a 2–3 minute cold plunge at 3°C–10°C for enhanced circulation, accelerated muscle recovery, and reduced systemic inflammation. Always stay well hydrated.
Timber Care & Maintenance
Canadian Hemlock naturally resists odours and moisture inside the home. For outdoor spruce saunas, applying a breathable UV-resistant exterior stain once every 12–18 months preserves the golden wood against UK weather.
