Rinnai
Visit Website

The Domusa Dual Clima HT Pro Air-to-Water Heat Pump is an advanced, high-performance solution designed for high-temperature applications. Capable of achieving a flow temperature up to 75°C, making it suitable for heating systems that require higher temperatures, such as radiators in existing homes or for new builds.

Details
Scope of use
  • Residential and commercial heating where higher flow temperatures are required.
  • Residential — radiators are suitable for single or multi storey stand-alone dwellings
  • Ideal for replacing older systems that use conventional fossil fuels or less efficient heat pumps.
  • Strategic placement of radiators throughout the home guarantees uniform, even heating effectively eliminating any cold spots and ensuring a cosy environment in every room
  • Designed to withstand all climate zones —can efficiently operate even in extreme conditions with a minimum outdoor air temperature of -20°C
  • Radiators provide a highly responsive and flexible heating option, ideal for both new constructions and existing homes. They quickly heat up and cool down, perfectly suited to New Zealand's ever-changing weather patterns
  • Can be integrated with solar power systems
  • Can be integrated into DHW (Domestic Hot Water) production for year-round comfort
Features
  • Natural Refrigerant (R290): Uses R290, a natural, non-toxic refrigerant with an extremely low Global Warming Potential (GWP) of 3. This contributes to an eco-friendlier operation and reduces environmental impact.
  • Compact and Efficient: The heat pump has a True Monobloc design, meaning all the components, including the PRV, AAV, expansion vessel, and pressure gauge, are factory-fitted. This simplifies installation and reduces space requirements.
  • Single-phase Inverter Compressor: Features a variable-speed compressor for greater efficiency and adaptive performance. The system adjusts its output to match demand, increasing both energy efficiency and comfort.
  • Low Refrigerant Charge: A smaller charge of refrigerant means improved safety and environmental benefits, contributing to its low carbon footprint.
  • Wide Operating Range: It can operate effectively even in colder climates with an outdoor temperature as low as -20°C.
  • High Coefficient of Performance (COP): The pump delivers a COP of 4.69 for the 16kW model and 4.47 for the 12kW model, meaning it delivers more heating energy compared to the electrical energy it consumes, maximising efficiency.
