Daikin Altherma 3 R 6 kW Air-to-Water Heat Pump

The Daikin Altherma 3 R 6 kW is an air-to-water heat pump designed to extract thermal energy from outdoor air and transfer it to a hydronic heating system.

Unlike a conventional air conditioner that directly conditions indoor air, an air-to-water heat pump supplies heated or cooled water for compatible systems such as:

• Underfloor heating
• Low-temperature radiators
• Fan-coil units
• Compatible domestic hot water systems
• Other suitable hydronic heating and cooling applications

This makes the Altherma 3 R particularly relevant to customers looking for a Daikin air source heat pump for central heating.

EHBX08E6V Indoor Unit

The EHBX08E6V is the wall-mounted indoor hydrobox used in this configuration.

The unit contains the hydraulic components required to connect the heat pump to the building’s water-based heating and cooling system.

Daikin’s current portfolio identifies EHBH/X-E wall-mounted indoor units within the Altherma 3 R 4–6–8 kW family.

The EHBX configuration is the version intended for applications where both heating and cooling are required.

ERGA06EVH Outdoor Unit

The ERGA06EVH is the outdoor heat-pump unit in this 6 kW configuration.

Daikin documentation lists ERGA06EVH with the EHBX08E6V indoor unit as a specific Altherma 3 R combination.

The outdoor unit uses inverter technology to modulate operation according to the heating or cooling demand.

6 kW Heating Capacity

The Daikin Altherma 3 R 6 kW system is designed around a nominal heating output of approximately 6.0 kW under the applicable A7/W35 rating condition.

Daikin’s technical data for EHBX08E6V + ERGA06EVH lists:

Heating capacity: 6.0 kW

at the specified average-climate A condition with 35°C leaving-water temperature.

Actual heating output varies according to outdoor temperature, leaving-water temperature and operating conditions.

Heating and Cooling

The EHBX X-version configuration provides both heating and cooling capability.

This allows the system to support:

Winter heating

The heat pump transfers thermal energy from outdoor air into the building’s hydronic heating system.

Summer cooling

When correctly configured with compatible emitters, the system can provide chilled water for suitable fan coils or other compatible cooling systems.

Consequently, the Daikin Altherma 3 R can serve as a year-round heating and cooling solution rather than a heating-only appliance.

Compatible Domestic Hot Water Tanks

The EuroFuelSupply configuration does not include a domestic hot water tank.

However, the EHBX08E6V can be combined with a compatible external DHW tank.

Suitable tank configurations should be selected according to the project’s hot-water requirements and the manufacturer’s compatibility information.

This makes the wall-mounted version particularly flexible because the installer can select a separate domestic hot water cylinder according to the property’s requirements.

R-32 Refrigerant

The Daikin Altherma 3 R uses R-32 refrigerant.

R-32 is used throughout Daikin’s European Altherma 3 R range. Refrigerant work must be carried out by appropriately qualified professionals in accordance with applicable European and local regulations.

Inverter Technology

The ERGA06EVH outdoor unit uses inverter technology to adjust compressor operation according to the required heating or cooling load.

Instead of operating continuously at a single fixed output, the system can modulate its capacity to respond to changing demand.

This helps support stable indoor temperatures and efficient operation.

Actual energy consumption depends on climate, building insulation, system design, water temperature, operating hours and user settings.

Seasonal Energy Efficiency

The Daikin Altherma 3 R 6 kW configuration is designed for high seasonal efficiency.

Daikin’s Altherma documentation identifies the range with seasonal efficiencies reaching A+++ under applicable low-temperature heating conditions.

For the exact EHBX08E6V + ERGA06EVH combination, the published technical data should be used when specifying the final energy label and seasonal efficiency figures.

Operation in Cold Weather

The ERGA06EVH outdoor unit is designed to operate in low outdoor temperatures.

The documented operating range extends to approximately -25°C in heating mode for this Altherma 3 R configuration.

Actual heating performance at low outdoor temperatures depends on the operating point, water temperature and system configuration.

Wall-Mounted Indoor Design

The EHBX08E6V is a wall-mounted indoor hydrobox.

Its vertical configuration can help save floor space compared with floor-standing hydrobox designs.

Daikin describes the wall-mounted Altherma 3 R indoor unit as a compact solution suitable for installations where available installation space needs to be considered.

Daikin Onecta and Smart Control

Compatible Daikin Altherma systems can support smart control and remote management depending on the installed control configuration and accessories.

The EuroFuelSupply listing specifies WiFi/app-based control capability for this system.

Before installation, confirm the exact control components and connectivity requirements for the supplied configuration.

• Properties requiring heating and cooling

The correct heat-pump size should always be determined using a professional heat-loss calculation rather than relying solely on floor area.

Why Choose the Daikin Altherma 3 R 6 kW?

The Daikin Altherma 3 R 6 kW provides a flexible alternative to conventional fossil-fuel heating systems by using outdoor air as the heat source.

Its wall-mounted EHBX08E6V indoor hydrobox helps save floor space, while the ERGA06EVH outdoor unit provides the heat-pump generation required for the system.

Key advantages include:

6 kW heating capacity + heating and cooling + inverter operation + R-32 refrigerant + wall-mounted indoor unit + external DHW compatibility

This combination makes it particularly suitable for customers planning a modern air-to-water heating system.

Heating System Compatibility

The Altherma 3 R is designed to work with suitable hydronic heating emitters.

Potential systems include:

Underfloor heating

Low-temperature underfloor heating is particularly well suited to air-to-water heat pumps.

Fan-coil units

Compatible fan coils can provide both heating and cooling.

Low-temperature radiators

Radiators designed or sized for suitable lower water temperatures can also be used.

System compatibility should be verified by the installer before purchase.

Installation Requirements

The Daikin Altherma 3 R 6 kW must be installed and commissioned by an appropriately qualified heat-pump professional.

Installation planning should consider:

• Building heat-loss calculation
• Heat-pump sizing
• Indoor hydrobox location
• Outdoor unit location
• Hydraulic connections
• Refrigerant pipework
• Electrical supply
• Expansion vessel requirements
• Heating emitters
• Condensate management
• Domestic hot water requirements
