Aira Indoor Unit
Your Aira Indoor Unit is where it all happens. It stores hot water, sends it to your taps and showers and fine-tunes efficiency thanks to Aira Intelligence. It even keeps you in the loop with Intuitive Light Cues.
Available in 100L or 250L, it’s sized to match your home’s hot water needs.
What’s included in this system?
The Aira Indoor Unit works seamlessly with a buffer tank and outdoor unit to efficiently heat your home and hot water.
Outdoor unit
The outdoor unit draws in and extracts heat from the fresh air outside to heat your home and hot water.
Buffer tank
The buffer tank is where hot water for your radiators and underfloor heating system is stored.
Buffer tank
Available in 40L and 100L, your buffer tank quietly does a big job.
- Keeps hot water ready for your radiators or underfloor heating.
- Manages flow rates & oversees defrost cycles to keep your system running like clockwork.
- Silences those annoying knocking sounds when temperature shifts try to cause a racket.
- Helps your system go the distance by cutting out unnecessary stop-start cycles.
It's the small details that make a big difference. That’s why every Aira installation includes one.
