Daikin Altherma 3 GEO Heating and Cooling Technology

The Daikin Altherma 3 GEO EGSAX10D9W is a reversible ground-source heat pump.

Therefore, the system can provide:

• Space heating
• Active cooling
• Domestic hot water

Unlike an air-source heat pump, a ground-source system uses energy from a properly designed geothermal source. Consequently, the complete installation must be planned according to the property’s heating requirements and the available ground-source solution.

Integrated 180L Domestic Hot-Water Tank

One of the key features of the Daikin EGSAX10D9W is its integrated 180 litre domestic hot-water tank.

The stainless-steel tank is incorporated into the floor-standing indoor unit. As a result, the system combines important heating and domestic-hot-water functions in one integrated design.

Key benefits include:

• Integrated hot-water storage
• Space-saving equipment layout
• Heating and hot water from one system
• Stainless-steel domestic hot-water tank
• Suitable for professionally designed residential installations

High Heating Performance

According to Daikin’s published specifications, the EGSAX10D9W has:

• Minimum heating capacity: 0.85 kW
• Nominal heating capacity: approximately 5.49 kW
• Maximum heating capacity: approximately 9.55 kW

The exact performance achieved in a real installation depends on operating conditions and system design.

For this reason, a qualified installer should calculate the property’s heat loss before selecting the final heat-pump capacity.

Heating Water Temperatures up to 65°C

The Daikin Altherma 3 GEO range can deliver heating-water temperatures up to 65°C within its specified operating range.

This provides flexibility for compatible hydronic heating systems.

Depending on the installation design, suitable applications may include:

• Underfloor heating
• Underfloor cooling
• Fan-coil units
• Suitable radiator systems

However, system compatibility should always be confirmed by a qualified heating professional.

Efficient R32 Refrigerant Technology

The EGSAX10D9W uses R32 refrigerant.

The Daikin Altherma 3 GEO range combines modern ground-source heat-pump technology with high seasonal efficiency performance under specified operating conditions.

For European homeowners and property developers, energy efficiency can be an important factor when selecting a renewable heating solution.

Active Cooling Capability

The EGSAX10D9W is a reversible model, allowing the system to provide active cooling when connected to a correctly designed compatible installation.

This means one professionally designed system can support both winter heating and summer cooling requirements.

Consequently, the Daikin Altherma 3 GEO can be an attractive option for suitable properties requiring year-round indoor climate control.

Designed for Suitable European Residential Applications

The Daikin Altherma 3 GEO EGSAX10D9W is relevant for suitable residential heating projects across Europe.

Potential applications include:

• New-build homes
• Energy-efficient houses
• Residential renovation projects
• Properties with underfloor heating
• Homes requiring integrated domestic hot water
• Suitable renewable-energy projects
• Properties with professionally designed geothermal systems

Local installation regulations and ground-source requirements should always be checked before installation.
