Question 1

Will my heat pump always be on and working all year round?

Accepted Answer

For many UK homeowners, it may seem strange not to turn their heating system “off”, especially when we're so accustomed to traditional boilers. However, a heat pump is designed to always be “on”.

With the help of Aira Intelligence, the Aira Heat Pump will always heat enough water for your home’s taps and showers and maintain a cosy temperature inside your home. However, on warmer days, particularly in the summer, your home may not need much heating – or any at all.

For example, if you’ve set your indoor temperature to 20°C and the weather is warm enough that the indoor temperature rises above this, your heat pump will stop heating your home. Once the temperature drops below 20°C, your heat pump will automatically and efficiently resume heating your home. This approach is more efficient because it allows the heat pump to maintain a steady, cosy temperature without the energy spikes that come from repeatedly turning the system on and off.

So yes, your heat pump is “on” all year round – but it automatically adjusts to you indoor temperature and the seasons. That’s why in the winter your heat pump will provide more heating to maintain your perfect indoor climate. When temperatures rise in the summer, it will provide less heating – if any at all.

Question 2

My heat pump is making noise. Is that normal?

Accepted Answer

When in operation, the outdoor unit of your Aira Heat Pump system emits a gentle hum, typically between 46 and 51 decibels*, depending on the size of your unit. At these levels, the sound blends seamlessly into the background, so you'll barely notice it.

During colder weather, your heat pump may need to work a bit harder to keep your home warm and your water hot, which might cause noise levels to rise slightly. Your unit may also make a gentle wheezing sound during a defrost cycle. This is completely normal and should last about 30 seconds.

However, if your Aira Heat Pump consistently makes loud noises, please contact our 24/7 Customer Support team on 0330 822 5493.

Question 3

How do I increase my indoor temperature?

Accepted Answer

Once you’ve set your desired indoor temperature and the amount of hot water you need a day, your Aira Heat Pump takes care of the rest, heating your home and water in the most efficient way possible. There is no need to make any adjustments. In fact, your heat pump works best if left to do its job. But if you do want to make any changes, you can by using the Aira Home Energy app.

Following your installation, your Clean Energy Technician will guide you through downloading and using the app – it’s incredibly simple. And, with Aira Intelligence, the Aira Heat Pump system will intuitively learn and adapt to your home routines to maintain your indoor temperature with optimal efficiency. Keeping you cosy while saving you even more on your energy costs.

Question 5

Will I be without hot water and heating during installation?

Accepted Answer

On the first day of your heat pump installation, our Aira Technicians will keep you fully informed about any temporary service interruptions (whether that’s gas, water, or electricity). We’ll provide you with a clear timeline so you’ll know exactly when heating and hot water will be back up and running.

While there may be a brief period without hot water or heating, we’ll work quickly and efficiently to get everything restored, making the process as smooth as possible for you. You’ll always know what to expect, and we’ll make sure to keep disruptions to a minimum.

Question 6

How hot will my water be with an Aira Heat Pump?

Accepted Answer

The hot water temperature for your home's taps and showers is typically set to 55°C for our 250L indoor units and 60°C for our 100L indoor units. This ensures the heat pump operates efficiently while maintaining its capacity. A safety valve is installed outside the unit to prevent scalding.

Question 7

What is the maximum output temperature the heat pump can provide for my heating?

Accepted Answer

Our heat pumps can provide heating system water up to 75°C. However, output temperatures – or flow temperatures – rarely need to be that high for efficient heating.

In most homes, a lower flow temperature of around 35-55°C is more than sufficient to keep your home warm and comfortable, while also improving the system's efficiency and reducing energy consumption.

If necessary, the system will automatically adjust to provide higher hot water temperatures to ensure your desired indoor temperature is maintained.
