Daikin Altherma 3 small monobloc
An all-in-one outdoor air-to-water heat pump designed to minimise indoor equipment requirements while delivering efficient home heating and optional domestic hot water.
Final model, capacity, cylinder and system design are subject to a property survey and room-by-room heat-loss calculation.
Why consider the Daikin Altherma 3 small monobloc?
All-in-one outdoor unit
The main hydraulic components are integrated into the monobloc outdoor unit.
Up to A+++
Applicable low-temperature configurations achieve an energy label up to A+++.
Designed for limited indoor space
No separate indoor refrigerant unit is required, helping reduce indoor equipment needs.
Cold-weather operation
Applicable Daikin Altherma 3 M models are designed to operate down to -25°C.
Domestic hot-water compatible
The system can be combined with a correctly sized hot-water cylinder.
Connected control
Compatible models support Daikin smart controls and Onecta connectivity.
Specifications vary by model, output and system configuration. JMG Renewables will identify the exact model in your written quotation. View manufacturer information.
Is this system suitable for your home?
Suitable smaller homes where the calculated heat load matches the available low-capacity range.
Suitability depends on calculated heat loss, required flow temperature, radiator or underfloor-heating performance, electrical supply, hot-water demand, pipe routes and outdoor-unit positioning.
Your survey should confirm
- Required heating output
- Design flow temperature
- Radiator or emitter upgrades
- Hot-water cylinder capacity
- Outdoor-unit location and acoustics
- Electrical and pipework requirements

Daikin Altherma 3 small monobloc FAQs
What capacity do I need?
The correct capacity must be calculated from a room-by-room heat-loss assessment. Floor area alone is not enough.
What cylinder size will be included?
The cylinder is selected for household hot-water demand, available space and the system design rather than supplied as one fixed size.
Will my radiators need replacing?
Existing emitters are checked against the required system temperatures. Only the upgrades required by the design should be included.
Is the installation free with the grant?
No. The grant contributes towards an eligible installation; the remaining cost depends on the property-specific quotation.
