💧 CCEI Anti-Frost Device DHG-2 – Automatic Pool Frost Protection System
❄️ Protect Your Pool Investment From Freezing Damage With Intelligent Temperature-Activated Pump Control
📋 Product Overview
The CCEI DHG-2 Anti-Frost Device is a sophisticated frost protection system engineered to safeguard your pool’s water and filtration equipment during cold weather conditions. This intelligent controller continuously monitors ambient or water temperatures using a precision TNC sensor and automatically activates your filtration pump when freezing conditions threaten.
When temperatures drop below the preset threshold, the DHG-2 forces your pump to circulate water throughout the system. This constant movement prevents ice formation in pipes, fittings, and equipment by raising the freezing point through increased pressure whilst drawing warmer water from the pool’s depths to the surface. The result is comprehensive protection against the costly damage that frozen pipes and equipment can cause.
Manufactured by CCEI in France, this robust IP65-rated device is built for outdoor installation and complies fully with European safety directives. With factory-preset temperature settings that can be easily adjusted to suit your specific installation, the DHG-2 provides reliable, set-and-forget frost protection for pools of all sizes.

💰 Usage Costs & Running Expenses
📊 Annual Running Cost Calculation
The DHG-2 consumes 30W when operating. However, unlike a pool pump that runs continuously during frost events, the DHG-2 control unit itself has minimal impact on your energy bills whilst providing invaluable protection.
DHG-2 Controller Running Cost:
- Power consumption: 0.03 kW
- Typical active monitoring hours: Estimated 2,000 hours during winter months (October-March)
- Current UK electricity rate: £0.2635 per kWh (Ofgem Price Cap Q4 2025)
- ✅ Annual controller cost: 0.03 kW × 2,000 hours × £0.2635 = £15.81 per year
🏊 Total System Running Cost (Including Pump Activation)
The real consideration is the pump running time during frost events. The DHG-2 intelligently minimises this by:
Scenario: Typical UK Winter (30 frost nights averaging 6 hours each)
- Forced pump run time: 30 nights × 6 hours = 180 hours
- Average pool pump power: 0.75 kW (typical single-speed pump)
- Energy rate: £0.2635 per kWh
Cost of frost-protection pump operation:
- ✅ Pump cost: 0.75 kW × 180 hours × £0.2635 = £35.57 per season
- ✅ Controller cost: £15.81 per season
- ✅ Total frost protection cost: £51.38 per winter season
💡 Cost Comparison: Protection vs No Protection
| Scenario | Annual Cost |
|---|---|
| ✅ With DHG-2 Protection | ~£51 per winter |
| ❌ Without Protection (Frost Damage) | £500 – £5,000+ repair costs |
💰 Potential Savings: A single frozen pipe incident can cost hundreds to thousands of pounds in repairs. The DHG-2 pays for itself many times over by preventing just one frost damage event.
🎯 Real World Applications
🏊♂️ Outdoor Swimming Pools
The primary application for the DHG-2. Outdoor pools are highly vulnerable to frost damage during winter months. The device monitors temperatures and automatically circulates water to prevent ice formation in surface skimmers, return jets, and underground pipework. Ideal for pools that remain filled over winter.
🏢 Commercial Pool Facilities
Hotels, leisure centres, and holiday parks benefit from automated frost protection that operates reliably without staff intervention. The DHG-2 protects valuable pool infrastructure during overnight and weekend periods when facilities may be unattended, providing peace of mind and reducing maintenance call-out costs.
🛁 Hot Tub & Spa Installations
While hot tubs typically maintain heated water, the surrounding pipework and external components can still be vulnerable during extended power outages or when units are winterised. The DHG-2 provides an additional safety layer for high-value spa installations.
🌊 Water Features & Ornamental Ponds
Garden water features, koi ponds, and ornamental fountains with pump systems can utilise the DHG-2 to prevent freezing damage. The precise temperature sensing ensures pumps only operate when genuinely needed, protecting both equipment and aquatic life.
🔄 Retrofit Installations
Perfect for upgrading existing pool systems that lack frost protection. The DHG-2’s universal compatibility and simple wiring requirements make it straightforward to add intelligent frost protection to virtually any pump-based water system.
💡 Cost Savings Examples
📍 Scenario 1: Preventing Pipe Burst Damage
A single frozen underground pipe can cost:
- ❌ Emergency plumber call-out: £150-£300
- ❌ Pipe excavation and repair: £500-£1,500
- ❌ Pool draining and refilling: £100-£300
- ❌ Chemical rebalancing: £50-£100
- ❌ Total potential damage: £800 – £2,200
✅ DHG-2 investment: One-time purchase prevents repeated risk 💰 ROI achieved after preventing just ONE frost incident
📍 Scenario 2: Pump and Filter Equipment Protection
Frozen water inside pump housings and filter vessels can crack casings:
- ❌ Replacement pump: £300-£800
- ❌ Replacement filter: £400-£1,200
- ❌ Installation labour: £150-£300
- ❌ Total potential damage: £850 – £2,300
✅ Annual protection cost with DHG-2: ~£51 📈 Protection value: 17-45× return on annual running cost
📍 Scenario 3: Five-Year Protection Investment
Over a typical five-year period:
- ✅ DHG-2 total running cost: 5 × £51 = £255
- ❌ Statistical likelihood of frost damage without protection (UK climate): High
- 💰 Lifetime protection value: Potentially £5,000+ in prevented repairs
⏱ Payback period: Immediate upon preventing first frost damage event
