💷 Running Costs

Energy Rate Used: £0.245/kWh (UK average rate – December 2024, Ofgem Price Cap)

The Harvia Frosty’s running costs depend primarily on how frequently you use it and your ambient room/outdoor temperature. The cooling unit operates intermittently to maintain your set temperature rather than running continuously.

Estimated Annual Running Costs

Usage Pattern	Sessions/Week	Estimated Annual Cost
🏠 Light Use	2-3	£75 – £120
🏠 Regular Use	4-5	£120 – £180
🧖 Frequent Use	6-7	£180 – £250

Cost Factors to Consider

• Ambient Temperature: Higher ambient temperatures require more cooling energy
• Target Temperature: Lower target temperatures (closer to 4°C) consume more energy
• Cover Usage: Consistently using the insulated cover significantly reduces energy consumption
• Installation Location: Indoor installations typically require less cooling than outdoor placements

💡 Energy-Saving Tip: The insulated cover is essential for maintaining temperature efficiently. Always replace the cover immediately after use to minimise energy consumption and keep your cold plunge ready for the next session.

⚠️ Actual costs will vary based on usage patterns, ambient conditions, and current energy rates.

🌡️ The Science of Cold Therapy

The Harvia Frosty enables you to access evidence-based cold water immersion benefits that have been documented in peer-reviewed research:

Reduced Pain & Inflammation – Cold water immersion constricts blood vessels, reducing inflammation and blocking pain signals. Studies by Abaïdia et al. (2017) and Angelopoulos et al. (2022) demonstrate significant pain reduction following cold immersion.

Improved Immunity – Regular cold exposure activates the immune system. Research by Dugué et al. (2000) and Kox et al. (2014) shows improved immune markers in regular cold-water bathers.

Stress Reduction & Mood Enhancement – Cold immersion boosts norepinephrine production, which is linked to improved mood. Studies by Huttunen et al. (2004) demonstrate enhanced wellbeing following cold exposure.

Better Sleep Quality – Pre-sleep cold exposure can increase deep sleep duration. Research by Chauvineau et al. (2021) shows reduced nighttime waking following cold immersion.

Brown Fat Activation – Cold exposure activates metabolically beneficial brown fat. Studies by Blondin et al. (2014) and Yoneshiro et al. (2019) demonstrate increased brown fat activity with regular cold exposure.

Faster Athletic Recovery – Cold water reduces post-exercise inflammation and muscle fatigue. Research by Brophy-Williams et al. (2011) confirms accelerated recovery when cold immersion follows exercise.
