Question 1

What is an air source heat pump?

Accepted Answer

An air source heat pump takes the free air from outside your home and turns it into energy to heat your rooms and water. Designed to work in temperatures as low as -20 degrees celsius, they act as a more sustainable and cost-effective alternative to traditional heating systems.

Question 2

What are the benefits of getting a heat pump?

Accepted Answer

Air source heat pumps are four times more efficient than gas boilers, emit 75% less carbon and are much more environmentally friendly. Switching to a heat pump will help you save on your energy bills. If you don't have any other gas appliances in your home, you pay another gas bill ever again.

Question 3

Is it worth getting a heat pump?

Accepted Answer

There are a number of reasons why an air to water heat pump is a worthwhile investment:

Heat pumps are four times more efficient than traditional gas and oil boilers, helping reduce your annual energy bills by up to £490 when combined with a smart tariff like Cosy Octopus.
They have an average life span of 15-20 years (a typical gas boiler usually lasts around 10 years).
They are compatible with both underfloor heating and radiators.
They can increase your home’s value by up to £8,000.
You can claim £7,500 off your heat pump with the government grant and pay 0% VAT
Heat pumps produce 75% fewer CO₂ emissions than traditional heating systems. 100% if you combine the heat pump with an Octopus Energy smart tariff like Cosy Octopus.

Question 4

Is a heat pump noisy?

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.

Question 7

Why is a heat pump more efficient than a boiler?

Accepted Answer

Heat pumps are four times more efficient than a gas boiler. For every 1kW energy put in, you get around 4kW out, compared to a boiler where you only get 0.9 kW out.

Heat pumps also represent better value for money, because they are much easier to maintain and last longer. They can last over 18 years – that's 25% longer than gas boilers (based on average lifetime of a boiler of 10-15 years).

Question 8

How much CO2 will I save using a heat pump?

Accepted Answer

You can save 75% of your carbon emissions by switching to a heat pump. Installing a heat pump is the most important change a household can make to reduce its CO2 emissions and requires the least effort (compared to changes to long-distance travel, travelling and eating habits).

Question 9

At what temperature does a heat pump stop working?

Accepted Answer

Heat pumps can provide effective heating in temperatures as low as -25 degrees celsius. Don't believe us? Just ask a Scandinavia, where heat pumps are the norm. As are sub-zero winters.

And, with the Aira Guarantee*, we promise your Aira Heat Pump will deliver a cosy indoor temperature between 18˚C-22˚C, even on the coldest day of the year (depending on the room and based on expected minimum temperatures).

If not, we’ll come and fix it.

Question 10

How much electricity do heat pumps use?

Accepted Answer

Even though a heat pump takes energy from the air, the process of turning that energy into heat for your home requires a small amount of electricity. 75% of the energy heat pumps use is generated entirely by free outside air while the remaining 25% is generated by your household electricity supply.

The quantity of heat delivered into your home is much greater than the quantity of electricity used to power the heat pump. This makes it much more sustainable, and cost effective, than a boiler.
