heDaikin Altherma 3 Bibloc 8 kW Wall-Mounted Air Source Heat Pump

Daikin Altherma 3 8 kW heat pump

The Daikin Altherma 3 Bibloc 8 kW is an air-to-water heat pump system designed to provide efficient heating for residential and low-energy buildings.

The wall-mounted Altherma 3 R W configuration combines a compact indoor hydraulic unit with an outdoor heat-pump unit, providing a flexible solution for modern heating installations. Daikin describes the Altherma 3 R W as suitable for low-energy houses and designed for flexible installation.

The system can also be configured with a separate domestic hot-water tank where required.

Daikin Altherma 3 8 kW Heat Pump

The Daikin Altherma 3 range is designed around air-to-water heat-pump technology.

Rather than directly heating indoor air like a conventional air conditioner, an air-to-water heat pump transfers heat from outdoor air into a water-based heating system.

This makes the technology suitable for applications such as:

• Underfloor heating
• Low-temperature radiators
• Heat-pump convectors
• Domestic hot-water systems when appropriately configured
• Residential heating
• Low-energy buildings
• New-build homes
• Renovation projects

Daikin identifies the Altherma 3 R as a low-temperature air-to-water heat-pump range suitable for new-build and smaller renovation applications.

---

8 kW-Class Heating

The Daikin Altherma 3 8 kW class is intended for appropriately sized residential heating applications.

Daikin’s technical documentation shows 8 kW-class wall-mounted combinations with nominal heating capacities around 7.5–7.8 kW, depending on the exact combination and test conditions.

For your product page, I recommend using:

8 kW-class air source heat pump

rather than claiming that every possible 8 kW combination delivers exactly 8.0 kW under every condition.

This is more technically accurate and protects the page from misleading specification claims.

Air-to-Water Heat Pump Technology

The Daikin Altherma 3 transfers thermal energy from outdoor air to water.

The heated water can then be circulated through compatible heating emitters such as:

• Underfloor heating
• Low-temperature radiators
• Heat-pump convectors

This makes Altherma 3 particularly relevant to customers searching for:

The Daikin air-to-water heat pump

Daikin air source heat pump

Wall-Mounted Indoor Unit

One of the main advantages of the Altherma 3 R W configuration is its compact wall-mounted indoor unit.

Daikin states that the wall-mounted design requires little installation space and has the hydraulic components and PCB positioned at the front for easier access.

The compact format can make the system suitable for homes where floor space is limited.

---

Compact Installation

Daikin’s Altherma 3 R W wall-mounted unit measures approximately:

840 × 440 × 390 mm

for the documented indoor-unit configurations.

The wall-mounted design allows the indoor hydraulic unit to be installed without requiring a large floor-standing cabinet.

Always check the exact dimensions of the particular set being supplied.

---

Heating and Cooling

The reversible versions of the Altherma 3 R W can provide both heating and cooling.

Daikin specifically describes the Altherma 3 R W wall-mounted system as offering heating and cooling, with optional domestic-hot-water connection.

If your particular EuroFuelSupply package is heating-only, remove “cooling” from the product description and structured data.

This distinction is important.

---

Domestic Hot Water

The Altherma 3 R W can be combined with a separate domestic hot-water tank.

Daikin states that the wall-mounted system can be combined with a stainless-steel tank or ECH₂O thermal store, depending on the installation configuration.

This allows customers to design a complete heating and hot-water solution around the heat pump.

Important

Do not describe a domestic hot-water tank as included unless it is actually part of the EuroFuelSupply package.

---

Underfloor Heating Compatibility

Air-to-water heat pumps are particularly well suited to low-temperature heating systems.

Daikin identifies Altherma 3 R as a low-temperature heat-pump solution and notes compatibility with systems such as underfloor heating and heat-pump convectors.

This makes the product highly relevant to customers searching for:

• Daikin heat pump for underfloor heating
• Daikin Altherma underfloor heating
• Air source heat pump for underfloor heating
• Daikin 8 kW underfloor heating heat pump

---

Low-Temperature Heating

The Altherma 3 R range is designed for low-temperature heating applications.

Daikin states that Altherma 3 R systems can deliver water temperatures up to 60°C, depending on the specific configuration.

The actual achievable flow temperature and efficiency depend on the exact model, outdoor conditions and operating mode.

---

R32 Refrigerant

The documented Daikin Altherma 3 R range uses R32 refrigerant.

Daikin’s documentation identifies R32 for the outdoor refrigerant circuit and gives a GWP of 675 for R32.

This is a valuable supporting European search term:

Daikin R32 air source heat pump

---

Energy Efficiency

Energy efficiency is one of the main reasons customers choose air-to-water heat pumps.

Daikin’s Altherma 3 technical documentation shows seasonal heating efficiency classes reaching A+++ at 35°C water outlet for the documented wall-mounted combinations.

Important SEO/product-data rule

Do not automatically put “A+++” in the product title.

The exact energy label depends on the specific combination and operating condition.

Use the current energy label for the exact product set you’re selling.

---

Smart Control

Compatible Daikin Altherma 3 systems can support connected control.

Daikin identifies the Onecta app as an optional control solution for compatible wall-mounted Altherma units, allowing users to control their indoor climate from a smartphone or tablet.

This gives the page additional search opportunities:

• Daikin Altherma Wi-Fi
• Daikin Altherma smart control
• Daikin heat pump Wi-Fi
• Daikin Onecta heat pump

Do not state that Wi-Fi is included unless the package includes the required adapter/module.

---

Quiet Indoor Operation

The documented Altherma 3 R W wall-mounted indoor units have a published sound pressure level around 28 dBA under the specified test condition.

For the outdoor unit, sound levels vary according to the exact outdoor model and operating mode.

Use the exact technical figures for your particular set rather than applying a generic Altherma sound level.

---

Suitable Applications

New-Build Homes

Altherma 3 R is designed for low-energy houses and can work particularly well with low-temperature heating systems.

Home Renovations

The system can be considered for appropriately designed renovation projects where the building’s heating system is compatible with heat-pump operation.
