Air Source Heat Pumps

Are you thinking about installing an air source heat pump? Wondering how much air source heat pumps cost or how much they could save you on your energy bills?

We’ve simplified everything you need to know about this low carbon heating alternative below.

What is an Air Source Heat Pump?

Air Source Heat Pumps

Air source heat pumps are one of the most used and simplest heat pumps to install. 

Firstly, air source heat pumps are based on the simple principle of heat transfer. Instead of burning fuel or converting electricity into heat, heat energy is transferred from outside into your home.  

For every 1kW of electricity, heat pumps will produce up to 4kW of heat energy for your home. Saving money and reducing your carbon footprint at the same time.

How Does an Air Source Heat Pump Work?

Heat pumps use a small amount of energy to transfer low-grade heat from the air to high-grade heat, heating water to high temperatures. Heated water can be used for hot water uses or space heating through radiators or underfloor heating systems.

By efficiently supplying hot water to the radiators at a constant temperature, air source heat pump’s provide a controlled level of warmth year-round and all the hot water you need. Essentially transferring heat from a ‘free heat source’ like the air to a ‘heat sink’ like your home. 

Air Source Heat Pumps
  1. The outside air is pumped across refrigerant filled coils, causing the liquid refrigerant to increase in temperature and produce hot gas.
  2. This hot refrigerant gas then enters the compressor where its temperature increases further as a results of the compression process. Much like a bicycle pump heats up during its use.
  3. The hot refrigerant gas is then condensed turning back into a liquid. This, now high-temperature water, is distributed via the buildings heating circuit to provide you with hot water and heat your home.

    This process is repeated to provide a constant temperature to the property.

Why Install an Air Source Heat Pump?

  • Save up to 50% on your annual heating and hot water bills.
  • Reduce your carbon emissions by up to 6,100kgs per year, helping in the fight against climate change.
  • Potential earnings of up to £11,000 in Renewable Heat Incentive (RHI) payments.
  • Receive over £1,600 in government funded Metering and Monitoring Service Package (MMSP) payments when you install an MMSP monitoring system.

Government Schemes

Air Source Heat Pumps

The government have introduced schemes to encourage the use of renewable technologies such as heat pumps and solar pv’s. To find out more and what schemes you might be eligible for, get in touch with a member of our team.

Still unsure? Why not read through more frequently asked questions.

How Big is an Air Source Heat Pump?

The heat pump will be positioned externally and will be approximately 1,000mm wide and between 740 to 1350mm tall. The depth of the unit is 330mm, but you will need to allow 300mm behind and 1,000mm in front of the unit.

We will locate the cylinder internally, usually in the same location of your current cylinder. The controls are typically mounted on the cylinder or nearby and are similar in size to that of a shoe box.

How Long Do Air Source Heat Pumps Take to Install?

On average Koze Home can fully install an air source heat pump in less than 4 days. If required, we can partially replace or install a complete radiator or underfloor heating system.

Can I Change the Temperature Within My Home?

The heat pump will be weather compensated which means that you set the temperature you want within your home. The heat pump then uses the least amount of electricity required to achieve the desired temperature.

As the outside temperature changes, the heat pump will automatically react and adjust to maintain your chosen temperature. It does this via strategically placed sensors within the system. You simply set your desired temperature and let the heat pump do the rest.

Our customers often report an improvement in comfort levels as the heat pump maintains a constant temperature.

Will an Air Source Heat Pump Keep Me Warm in Winter?

Yes, the system will be capable of providing heating and hot water throughout the year without any requirement for a supplementary boiler. They can provide up to 4 times as much heat as an electric heater using the same amount of energy.

Do I Need to Coordinate Any Other Trades on Site?

No, Koze Home can undertake the entire installation. From providing the complete design, supply, installation and commissioning of the system, without any need for third parties or subcontractors.

In short, we found that the biggest issue for customers is ensuring that everyone knows what and when their responsibility starts and ends. We have found that by offering the complete installation we ensure that we remain in control of the whole process. As well as being entirely responsible for the successful completion of the installation with our in-house installers reporting directly to Ecovision.

Does an Air Source Heat Pump Make a Lot of Noise?

An air source heat pump will make some noise when they are operating as a compressor and fan are in motion. However this noise is far less than you may think.

Before an air source heat pump can be installed they must pass a noise assessment. This is to ensure that you never hear the heat pump from inside your property. Furthermore, with a decibel rating similar to, or less than that of a conventional boiler, your neighbours shouldn’t even know it’s there.

Does an Air Source Heat Pump Require Lots of Maintenance?

Air source heat pumps generally require very little maintenance as they are a sealed unit. It is recommended that you inspect and clean your air source heat pump annually. Also clear any build-up of leaves or debris from behind the unit.

Koze home can complete this task as part of an annual service, leaving you with absolutely no maintenance requirements.

Will an Air Source Heat Pump Work With My Existing radiators?

Koze Home will have to complete a full room-by-room emitter (radiator) assessment before any installation takes place. This is to ensure your existing radiator circuit is capable of emitting the required heat. This is a government requirement in order to be eligible for the RHI subsidy.

We usually find that most of the radiators are suitable but some will need to be changed to meet the government’s accreditation standards. These changes will ensure the lowest possible running costs and the cost of any changes will be made clear in your quotation.
