• Indoor unit EBVX16S23D6V: hydraulic module with 230-liter DHW tank, includes integrated hydraulic components (circulation pump, expansion vessel, 3-way valve, magnetic filter), auxiliary electric heater (D6V models usually include a 6 kW heater), and control electronics accessible from the front.
• Outdoor unit ERLA14DV3: low-temperature air-to-water heat pump, R-32 refrigerant (Bluevolution series), designed for guaranteed operation down to −25 °C outdoor temperature. Compatible with remote control via app and optional WiFi module.
• DHW tank: 230 L, stainless steel, max DHW pressure ≈ 10 bar, max DHW temperature = 70 °C (according to catalog for 180/230 L tank).
• Outdoor temperature range for heating: down to -25 °C minimum for the outdoor unit.
• Refrigerant: R-32, approximate charge 3.8 kg (tCO₂ eq 2.57) for ERLA11-14DV3; same general series for ERLA14DV3.
• Outdoor unit refrigerant connections: liquid Ø 9.5 mm / gas Ø 15.9 mm.
• Dimensions and weight:
  • Indoor unit EBVX16S23D6V (230 L tank version): height ≈ 1,855 mm, width 595 mm, depth 634 mm.
  • Outdoor unit ERLA14DV3: height 870 mm, width 1,100 mm, depth 460 mm; weight 101 kg.

Extended Specifications

• Water supply temperature range for heating: typically 18-60 °C (according to catalog for similar combinations).
• Indoor unit material: pre-coated sheet metal for the outer panel.
• Approximate DHW tank heating time (230 L): for EBVX16S23D… combination, ≈ 56 min to raise from 10 °C to 45 °C under standard conditions.
• Typical seasonal efficiency: for set with 180/230 L tank, SCOP values ~4.60 (water 35 °C) and ~3.22 (water 55 °C) indicated in catalog file.
• Indoor installation footprint: compact installation with footprint ≈ 595×634 mm, height < 2 m for 230 L tank, making it easy to install in a technical room or garage.

Customer Benefits

• High energy efficiency even in demanding conditions thanks to inverter technology and design for low outdoor temperatures.
• Integrated 230-liter DHW tank meets significant hot water demands without the need for an additional external tank.
• Compact design of the indoor module with key components accessible from the front, making maintenance easier and reducing technical space requirements.
• R-32 refrigerant with lower environmental impact and positive implications for installation sustainability.
• All-in-one system (heating + DHW + cooling option) simplifies installation and reduces the need for multiple devices.
• Ready for smart remote control: monitoring and adjustment via smartphone/tablet, including home automation integration.

Recommended Applications

This set is especially suitable for single-family homes with medium-high heating demand (≈14 kW) and a need for 230 L of hot water, as well as renovation projects seeking to replace traditional systems with an integrated air-to-water heat pump. It is ideal when low-temperature emitters (underfloor heating, fan coils, or low-temperature radiators) are available to maximize the system's SCOP.

Important Considerations

• Installation must be carried out by a qualified technician and comply with current regulations (such as the country's thermal installation regulations, handling of fluorinated gases, etc.).
• Actual performance will depend on the home's insulation, water supply temperature, and outdoor climate. For optimal results, low-temperature emitters are recommended.
• Allow for installation space for the outdoor unit (clearance, ventilation, maintenance access) and for the indoor unit (height ≈1,855 m, footprint ≈595×634 mm), and consider electric backup when using the auxiliary heater.
• If using in cooling mode, consider suitable emitters and the management of condensate and dew point control.

Summary

In summary, the Daikin Altherma 3 Bibloc EBVX16S23D6V + ERLA14DV3 set offers a high-performance air-to-water heat pump solution, with 14 kW power, 230-liter DHW tank, R-32 refrigerant, operation down to –25 °C outdoors, compact design, advanced hydraulic integration, and optional smart control. It is an excellent choice for those seeking thermal comfort, hot water production, and energy efficiency in a single system.
