Ultra-High Temperature Heat Pumps

Although Toyesi has proudly manufactured heat pumps in Australia for over 30 years, we understand that some projects demand a different kind of solution. As industries increasingly transition away from high-temperature gas boiler systems—driven by rising costs, environmental targets, and looming supply constraints—the need for reliable, high-output alternatives has grown. To meet this challenge, we’ve partnered with leading international manufacturers to deliver advanced systems tailored for demanding applications. Thermace units represent the next generation of heating technology, offering superior performance, efficiency, and temperature stability where traditional heat pumps fall short.

🔥 The Future of High-Temperature Heating: Thermace’s 2-Stage Cascade Heat Pumps

With rising gas prices, looming phase-outs, and increasing supply concerns, businesses across Australia are transitioning away from gas-based heating systems. While this shift is relatively straightforward for swimming pools and domestic hot water, the commercial and industrial sectors face a tougher challenge—especially when high-temperature output is required.

⚠️ The Challenge: Temperature Limitations

Traditional gas systems easily deliver 65°C to 90°C water temperatures. Until recently, heat pumps were limited to 45°C to 65°C, often requiring backup gas heaters to meet demand.

✅ The Solution: Toyesi’s Ultra High-Temperature Heat Pumps

Our 2-stage cascade system delivers 65°C to 85°C hot water without backup heaters—a game-changer for commercial and process applications.

🌡️ Key Features:

• Dual Refrigerant Cascade:
  • R410A extracts ambient heat and preheats the system
  • R134a completes the cycle, delivering stable high-temperature output
  • Upgrade Refrigerant options include to R32 & R515B
• EVI + DC Inverter Technology:
  • Operates efficiently from –35°C to +50°C ambient
  • Maintains performance even in extreme climates
• Energy Savings:
  • Up to 30% lower consumption than traditional heat pumps

🔄 Why Cascade Beats CO₂

While CO₂ heat pumps pioneered high-temp solutions, Toyesi’s cascade system offers:

• Easier to service than a CO2 System
• More readily avaiable components.
• Superior low-ambient performance
• Consistent 75°C output year-round even down to minus 12 degrees.
• More affordable pricing than CO₂ systems in the 50–150 kW range

💡 Smarter Investment

Yes, the extra compressor stage adds upfront cost—but the efficiency, reliability, and temperature stability make Toyesi’s system the ideal go-to solution for 65°C to 85°C hot water projects.
