Is this system suitable for your home?
Homes where the pipe route or equipment position benefits from a split-system design.
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 3R Split 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.
