Choosing a new heating system can be a big decision, especially when you want to understand how heat pumps work and which type may suit your property. Daikin Altherma is a range of air-to-water heat pump systems designed to provide heating and, depending on the model, hot water and cooling.
In this guide, we look at the main Daikin Altherma options, how they differ and what to consider before choosing a system.
What Is a Daikin Altherma Heat Pump?
Daikin Altherma is a range of air-to-water heat pumps that uses energy from the outside air to produce heat for a building.
The system transfers heat into water, which can then be used for:
- Home heating
- Domestic hot water
- Cooling, where supported by the system
The exact features depend on the model and installation design. Daikin offers different configurations for new homes, replacement heating systems and other property requirements.
Main Types of Daikin Altherma Heat Pumps
Daikin Altherma is available in several system types. The right option depends on the building, existing heating system and required water temperature.
1. Low-Temperature Heat Pumps
Low-temperature Daikin Altherma systems are designed for heating applications where the property and heat emitters can operate effectively at lower water temperatures.
They may be suitable for new-build homes and properties with appropriately designed heating systems.
Before choosing this type, consider:
- Building insulation
- Heat loss
- Radiator or underfloor heating design
- Hot water requirements
- Available installation space
2. High-Temperature Heat Pumps
High-temperature Daikin Altherma models are designed for applications where higher water temperatures are required, including some heating system replacement projects.
They may be considered when replacing an existing boiler, but suitability depends on the property and system design. Existing radiators and pipework should be assessed rather than assumed to be suitable.
3. Mid-Temperature Heat Pumps
Mid-temperature models sit between low-temperature and high-temperature applications. They can be considered for selected replacement projects and larger homes, depending on the heating requirements.
The suitable operating temperature and system configuration should be confirmed using the property's heat-loss assessment.
4. Monobloc Heat Pumps
A monobloc heat pump combines key refrigeration components within the outdoor unit. The system connects to the property's heating and hot water arrangement through water-based connections.
Daikin Altherma monobloc models are available for selected air-to-water applications. Installation requirements depend on the specific product and system layout.
5. Split Heat Pumps
A split system uses separate outdoor and indoor units connected as part of the heat pump system.
Depending on the model, the indoor unit may provide heating system connections, hot water integration and other components required for operation.
Split and monobloc systems have different installation considerations, so the choice should be based on the property and project requirements.
What Can a Daikin Altherma System Provide?
Depending on the selected model, a Daikin Altherma system may support several home energy needs.
Space Heating
The heat pump transfers heat from outdoor air into the home's heating system. This can work with suitable radiators, underfloor heating or other compatible heat emitters.
Domestic Hot Water
Some Daikin Altherma systems can produce hot water using an integrated or separate cylinder arrangement. The cylinder size and configuration should match the property's requirements.
Cooling
Selected reversible systems can provide cooling as well as heating. Whether cooling is practical depends on the system design, indoor emitters and installation setup.
Smart Controls
Certain Daikin systems support control features through compatible products and the Daikin Onecta app. Available functions depend on the model and connected equipment.
What Should You Consider Before Choosing a Daikin Altherma Heat Pump?
There is no single Altherma model that suits every property. Before making a decision, consider the following.
Property heat loss: A heat-loss assessment helps determine the heating capacity required.
Existing radiators: Radiator size and operating temperature can affect system suitability.
Hot water demand: Consider the number of occupants, daily usage and cylinder requirements.
Available space: Check the space required for the outdoor unit, indoor equipment and any cylinder.
System type: Decide whether a low-temperature, mid-temperature, high-temperature, split or monobloc configuration is appropriate.
Installation requirements: The final design should be confirmed by a suitably qualified installer using the manufacturer's guidance.

Frequently Asked Questions
Are Daikin Altherma heat pumps suitable for older homes?
Some models are designed for heating system replacement, including high-temperature options. Suitability depends on the building, insulation, heat loss and existing heating system.
What is the difference between a split and monobloc heat pump?
A split system uses separate indoor and outdoor units connected through the refrigeration circuit. A monobloc system contains the main refrigeration components in the outdoor unit. The installation requirements differ.
Can Daikin Altherma provide hot water?
Yes, selected Altherma systems can provide domestic hot water when configured with suitable equipment.
Do all Daikin Altherma models provide cooling?
No. Cooling availability depends on the specific model and system design.
Which Daikin Altherma model should I choose?
The appropriate model depends on your property's heat demand, heating emitters, hot water needs, available space and installation requirements. A qualified professional can help assess the options.
Final Thoughts
Daikin Altherma offers several air-to-water heat pump configurations for different property and heating requirements. Understanding the difference between low-temperature, mid-temperature, high-temperature, split and monobloc systems can help you narrow down the options.
The best choice should be based on your building's requirements and the complete system design, rather than the model name alone.
