Daikin Altherma 3 Supra 16 kW Bi-Bloc Air-to-Water Heat Pump with Hydrokit

The Daikin Altherma 3 Supra 16 kW is a high-capacity air-to-water heat pump system designed to provide efficient heating, cooling and domestic hot water for appropriately sized residential and building applications.

This bi-bloc aerothermal heat pump system with Hydrokit uses energy extracted from outdoor air to provide heating and, depending on the system configuration, cooling and domestic hot water.

The Altherma platform is designed for European climates and offers a renewable heating alternative to conventional fossil-fuel heating systems.

European product information for the 16 kW Altherma configuration identifies the system around the EPRA16DV37 outdoor unit and ETBX16E6V7 Hydrokit indoor unit. Verify these references against the exact kit supplied before publishing them as your product’s model numbers.

Daikin Altherma 3 Supra 16 kW Heat Pump

The 16 kW capacity class makes this system suitable for larger residential properties and other appropriately designed applications where a higher-capacity air-to-water heat pump is required.

The system can be integrated with suitable hydronic heating equipment such as:

• Underfloor heating
• Radiators
• Fan coil units
• Low-temperature heating systems
• Domestic hot-water systems

The correct heat-pump capacity should always be determined using a professional heat-loss calculation rather than property size alone.

Air-to-Water Heat Pump Technology

The Daikin Altherma 3 Supra is an air-to-water heat pump.

Instead of generating heat through conventional combustion, the outdoor unit extracts thermal energy from the surrounding air and transfers that energy into the building’s water-based heating system.

This makes the system particularly suitable for homes and buildings using:

• Underfloor heating
• Radiators
• Fan coil units
• Domestic hot-water cylinders
• Other compatible hydronic heating systems

The result is one integrated heating solution capable of providing substantial amounts of heat using electricity and outdoor-air energy.

Bi-Bloc Heat Pump Design

The bi-bloc design separates the outdoor heat-pump unit from the indoor hydraulic equipment.

This configuration can offer flexibility when planning the installation because the outdoor refrigeration equipment and indoor water-side components are installed separately.

The Hydrokit handles important hydraulic functions within the system, helping simplify the overall system design when used with compatible Daikin components.

Daikin’s European Altherma documentation describes split systems with dedicated indoor and outdoor units and integrated hydraulic components depending on the configuration.

Hydrokit Indoor Unit

The Hydrokit is an important component of the Altherma system.

Depending on the exact configuration, the indoor unit incorporates the hydraulic components required to connect the heat pump to the building’s heating system.

This can simplify installation compared with assembling multiple separate hydraulic components.

The exact components included in your particular kit should be confirmed against the supplied Daikin configuration and technical documentation.

Heating, Cooling and Domestic Hot Water

A major advantage of an appropriately configured Daikin Altherma 3 system is its ability to provide more than space heating.

Depending on the selected system configuration, it can support:

Space Heating

Provide heating through compatible radiators, underfloor heating or fan coils.

Cooling

Support cooling through compatible low-temperature emitters or fan-coil systems where the installation is designed for cooling.

Domestic Hot Water

The Altherma platform can be integrated with compatible domestic-hot-water storage solutions.

This allows one heat-pump installation to form the foundation of a complete home climate and hot-water system.

High-Temperature Heating Capability

Daikin’s Altherma high-temperature range is designed to supply high leaving-water temperatures for applications such as radiator heating.

Daikin’s European documentation for the relevant Altherma 3 H HT range states that the outdoor unit can deliver 70°C leaving-water temperature at -15°C outdoor temperature using heat-pump operation only.

Important: Do not automatically apply the 70°C specification to every “Altherma 3 Supra 16” configuration. Confirm the exact outdoor and indoor model combination being sold before displaying this specification on the product page.

Designed for European Climates

Daikin Altherma systems are designed for heating applications across a range of European climates.

Daikin’s European product information states that relevant Altherma units can extract heat from outdoor air even at very low ambient temperatures, with certain high-temperature models specified for operation down to -28°C.

The actual operating range and performance depend on the specific model combination.

Daikin Altherma 3 16 kW Applications

The 16 kW system can be considered for appropriately designed:

Large Homes

A 16 kW air-to-water heat pump can be suitable for larger homes requiring substantial heating capacity.

Detached Houses

The system can provide centralized heating and domestic hot water when correctly designed.

Renovation Projects

Altherma can be considered when replacing older heating systems and transitioning to an air-source heat-pump solution.

Properties With Radiators

Suitable configurations can work with compatible radiators, including higher-temperature applications.

Underfloor Heating

Air-to-water heat pumps are particularly well suited to properly designed underfloor heating systems.

Small Commercial Buildings

The system may also be considered for suitable smaller commercial or mixed-use properties following a professional heat-load assessment.

Daikin Altherma 3 and Underfloor Heating

Underfloor heating is one of the most suitable applications for an air-to-water heat-pump system.

The large surface area of underfloor heating allows the system to deliver heat at relatively low water temperatures, which can help optimize heat-pump operation.

Daikin’s Altherma documentation also describes bi-zone configurations that can combine underfloor heating with radiators.

Daikin Altherma 3 With Radiators

The system can also be used with radiators when the system is correctly designed.

For an existing property, the installer should assess:

• Existing radiator size
• Required flow temperature
• Building insulation
• Heat loss
• Pipework
• Required heating capacity
• Outdoor design temperature

A professional assessment is particularly important when replacing an existing boiler with an air-to-water heat pump.

R-32 Refrigerant

Relevant Daikin Altherma 3 systems use R-32 refrigerant.

Daikin highlights R-32 across its Altherma range, including reduced refrigerant charge and lower global-warming impact compared with R-410A.

Refrigerant installation and servicing must be performed by appropriately qualified professionals and in accordance with applicable European regulations.

Daikin Onecta Connectivity

Compatible Daikin Altherma systems can support remote control through the Daikin Onecta app, depending on the exact configuration and accessories.

Daikin describes Onecta as allowing users to control indoor climate remotely using a smartphone or tablet.

Before publishing “Wi-Fi included,” however, verify whether connectivity is integrated, included as standard, or optional for the exact kit you are selling.

An air-source heat pump uses outdoor air as its renewable heat source rather than relying solely on combustion-based heating.

Professional Installation

The Daikin Altherma 3 Supra 16 kW is a professional heating system and should be designed, installed and commissioned by a suitably qualified heat-pump installer.

Before ordering, the installer should verify:

• Building heat loss
• Required heat-pump capacity
• Outdoor design temperature
• Heating-water temperature
• Radiator compatibility
• Underfloor-heating requirements
• Domestic-hot-water requirements
• Hydraulic design
• Refrigerant pipework
