Imagine diving into perfectly warm water in your above-ground pool or hot tub, even when the outside temperature has dropped to just 10°C. The Dantherm HPP6R 6kW Heat Pump makes this possible, delivering efficient, cost-effective heating specifically designed for smaller pools, above-ground installations, and spa environments.

Born from the collaboration between Calorex and the Dantherm Group—two titans in climate control engineering—the HPP6R packs professional-grade performance into a compact, whisper-quiet package. This isn’t an oversized industrial unit struggling to fit in your garden; it’s a purpose-built heating solution that delivers exactly what small to medium pool owners need without wasting energy or space.

🌟 Why the Dantherm HPP6R is Perfect for Your Pool

⚡ Right-Sized Power for Smaller Pools

With 6.1kW of heating capacity, the HPP6R is the Goldilocks solution—not too powerful (avoiding energy waste), not too weak (ensuring consistent warmth). It’s specifically engineered for:

• 🏊 Above-ground pools up to 50m³ (e.g., 8m x 4m x 1.5m depth)
• 🛁 Hot tubs and swim spas (3-6 person capacity)
• 🏡 Small in-ground pools up to 40m³ (with a good pool cover)
• 🌸 Garden plunge pools and compact residential installations

What This Means for You:

• 💰 Save up to 70% on heating costs compared to traditional electric heaters
• 🌍 Produce up to 5 times more energy than you consume (COP of 2.6-5.0)
• 📊 Heat efficiently without over-powering your system
• ⏱️ Extend your swimming season from April to October (6+ months!)

🤫 Ultra-Quiet Operation: Just 28dB

At only 28 decibels at 10 metres—quieter than a library whisper and softer than rustling leaves—the HPP6R is the quietest model in the entire Dantherm range. Your neighbours won’t even know it’s running, and you can enjoy peaceful poolside conversations, evening relaxation, or even leave it running overnight without any disturbance.

Perfect for:

• 🏡 Residential gardens with close neighbours
• 🛏️ Installations near bedrooms or living areas
• 🌙 Overnight heating schedules
• 🧘 Peaceful spa and relaxation environments

🎨 Compact & Stylish Design

Measuring just 933mm x 408mm x 793mm and weighing only 50kg, the HPP6R is one of the most compact pool heat pumps available. The sleek graphite grey ABS cabinet looks premium, not industrial, and its smaller footprint means:

✅ Easier installation in tight spaces
✅ Simple single-person positioning (with proper lifting technique)
✅ Attractive garden aesthetics
✅ Weather-resistant construction for years of outdoor exposure

🔧 Premium Components Engineered for Longevity

Professional-Grade Construction

🔹 Titanium Heat Exchanger
The gold standard for pool heating. Titanium doesn’t just resist corrosion—it’s virtually immune to it, even in harsh salt water environments. This ensures:

• Superior heat transfer efficiency
• Decades of reliable performance
• Perfect compatibility with salt chlorination systems
• No degradation from chemicals or pH fluctuations

🔹 Advanced Scroll/Rotary Compressor
Industrial-grade compression technology ensures consistent, reliable operation even during extended heat-up cycles.

🔹 Reverse Cycle Defrost System
Unlike basic heat pumps that struggle in cooler weather, the HPP6R operates effectively down to 3°C air temperature. This means:

• Early spring heating (March-April)
• Late autumn swimming (September-October)
• Reliable performance on cooler days
• 3-4 months of extra swimming per year

🔹 R410A Refrigerant
Modern, efficient refrigerant providing excellent thermodynamic properties for optimal heat pump performance across all operating conditions.

🔹 Weather-Resistant ABS Cabinet
Built to survive British weather extremes—rain, wind, frost, UV exposure, and humidity won’t phase this unit.

🎛️ Smart Features for Effortless Pool Management

✅ Precise Digital Temperature Control: Set and maintain your exact desired water temperature from 15°C to 40°C
✅ Integrated Touch-Screen Controller: Easy-to-use interface with clear temperature display
✅ ‘Smart’ Pool Pump Integration: Coordinates intelligently with your existing filtration system
✅ 24-Hour Timer Function: Program heating schedules to maximize savings during off-peak hours
✅ Built-in Condensate Drain: Prevents water accumulation that could damage components
✅ Water Flow Switch: Automatically protects against dry-running damage

💡 Real-World Energy Savings Comparison

Let’s compare the actual running costs for heating a 30m³ above-ground pool over a typical 6-month extended season (April – September):

Heating Method	Power Consumption	Annual Cost (approx.)
Traditional 6kW Electric Heater	6.0kW continuous	£2,520
Gas Heater	Equivalent	£2,280
Oil Heater	Equivalent	£2,800
Dantherm HPP6R Heat Pump	1.3-2.33kW	£740
💰 Your Savings with HPP6R	–	£1,780 – £2,060/year

Based on 8 hours daily operation at £0.28/kWh electricity rate. Savings of 70% compared to electric heating!

Monthly Running Cost Estimate:

For a 30m³ pool heated 8 hours daily:

• ☀️ Warm months (June-August): £100-120/month
• 🍂 Cooler months (April-May, Sept-Oct): £130-160/month
• ❄️ Off-season (with cover, maintenance mode): £40-60/month

That’s less than £5 per day to enjoy perfectly heated pool water!

⏱️ Heating Performance: What to Expect

Initial Heat-Up Times (from 15°C to 28°C):

Pool Size	Initial Heating Time	Daily Maintenance
20m³ above-ground	3-4 days	2-3 hours
30m³ above-ground	5-6 days	3-4 hours
40m³ small in-ground	6-8 days	4-5 hours
Hot tub (3m³)	12-18 hours	30-45 minutes

Times assume moderate weather (15-20°C ambient), good pool cover, and starting from cold. Actual times vary with weather conditions.

Daily Temperature Maintenance:

Once your pool reaches target temperature:

• 🌡️ Temperature rise per day: 1-2°C (depending on conditions)
• 🌡️ Heat loss overnight (no cover): 2-3°C
• 🌡️ Heat loss overnight (with cover): 0.5-1°C
• 🌡️ Typical running time: 4-8 hours per day

❓ Frequently Asked Questions

Q: How long does it take to heat my pool initially?

A: For a typical 30m³ above-ground pool, expect 5-6 days to heat from 15°C to 28°C. A hot tub (3m³) will heat in 12-18 hours. Once at temperature, daily maintenance requires only 3-4 hours of operation.

Q: What size pool is the HPP6R suitable for?

A: The HPP6R is perfect for pools up to 50m³ (with a good cover). Optimal performance for above-ground pools 20-40m³ and hot tubs/swim spas up to 12m³. For larger pools, consider the HPP8R or HPP12R models.

Q: How much does it cost to run per month?

A: For a 30m³ pool running 8 hours daily, expect £100-160/month depending on season and weather. That’s about £3-5 per day—roughly 70% cheaper than electric heating.

Q: Can I use this with a salt water pool or chlorine?

A: Absolutely! The titanium heat exchanger is completely resistant to salt, chlorine, and all pool chemicals. Perfect for any pool type.
