Maximise your heat pump savings
Aira Zero allows Aira to adjust your system to heat your home and water when energy prices are lower and use stored heat and hot water during peak times when energy is more expensive.
Further reducing your energy costs without compromising comfort.

How does Aira Zero work?
Aira Zero is a three rate daily tariff consisting of:
- A day rate that applies for most of the day and set to your local area
- Three discounted periods, each 49% cheaper than the day rate
- A peak rate, priced 50% above the day rate
By maximising energy usage during discounted periods and minimising it during peak times, your heat pump can save you up to an additional 22% on your energy costs.*
