Air Source Heat Pumps

Air Source Heat Pumps can save you money compared to conventional oil or gas central heating, while helping to protect the environment.

B.A.R. and Sons can supply and fit an air source heat pump, which will heat your home using heat energy drawn from the environment. Grant and Worcester Bosch Heat Pumps offer some of the highest efficiencies on the market.

Our M.C.S. accreditation, means that you could also benefit from Ofgem’s new Boiler Upgrade Scheme (B.U.S.), which could pay £5,000.00 towards the installation of your air source heat pump.

The Boiler Upgrade Scheme

The Boiler Upgrade Scheme was introduced by Ofgem to replace the Renewable Heating Incentive, to encourage home owners to replace their gas or oil boilers with a more enviromentally friendly, low carbon alternative.

The scheme is open to home owners who wish to upgrade to an Air Source Heat Pump or a Ground Source Heat Pump, and in some cases also covers Biomass boiler installations. It is also open to ‘Self Builders’ who are building their own new homes.

The scheme pays a fixed sum of £5,000.00 towards the installation of an Air Source Heat Pump and £6,000.00 towards the installation of a Ground Source Heat Pump. Where a property is unsuitable for a heat pump and is ‘off the gas grid’, the scheme will pay £5,000.00 towards the installation of a biomass boiler.

Owner eligibility

You may be eligible if you:

  • live in England or Wales
  • own your property (whether this is a home or a small non-domestic property)

Private landlords and second-home owners are eligible.

You can still apply if you’ve received separate funding for energy efficiency upgrades such as insulation, doors or windows.

Property eligibility

The scheme is open to domestic and small non-domestic properties with:

  • an installation capacity up to 45kWth (this covers most homes)
  • a current energy performance certificate (EPC), with no outstanding recommendations for loft or cavity wall insulation

If you own a self-build property

To be eligible, a self-build must have:

  • been built mainly using the labour or resources of the first owner
  • not been owned by a business or organisation

You will need to provide proof to your installer that your property is a self-build, for example a copy of the title deeds.

Excluded properties

Grants are not available for:

  • social housing
  • new build properties (apart from certain self-builds)
  • properties that have already had government funding or support for a heat pump or biomass boiler

Client Testimonials

“They fitted our boiler system .. Was punctual polite and efficient ..We use them to service yearly and wouldnt use anyone else. Definitely 5 star.”

Shani Hanson

“Had BAR come and install new pressurised system to update an old hot water system. The guys did a great job and ensured everything was done quickly and with minimal disruption and mess. Thanks!”

Daniel Griffin

Once again please pass on our thanks to the whole team for all their work during the installation of the hot water/heating system. The whole process from start to finish has been carried out by professional and caring people who have been a pleasure to work with.

Key steps when having an Air Source Heat Pump installed

Getting the most out of your Ground Source or Air Source Heat Pump, depends on a system being correctly designed and installed, which is why it’s important to use an experienced MCS accredited installer, such as B.A.R. & Sons. To make sure of a system that perfectly matches your home and your heating and hot water needs, a we will work to three key stages:

1. Pre-design assessment

Not all properties are suitable for a heat pump so it is important to determine if a heat pump is right for your home.

With years of experience in the renewable heating industry, B.A.R. & Sons will be able to advise you on the most beneficial system for you. We can produce a budgetary estimate, detailing the work required and including different options, if necessary.

Because we can supply conventional heating systems too, like gas or oil boilers, we won’t pressure you in to buying a heating system that isn’t suitable for your home or lifestyle.

2. Detailed Design and Specification

We will begin the detailed design process. This will include a full ‘heat loss’ survey to determine the heating and domestic hot water needs of your property and calculations to determine if your current radiators will be sufficient to ensure the heat is transferred efficiently into your home.

All of this information will be included in our full quotation, along with a performance estimate detailing the energy savings that you could receive.

3. Installation

Our team of qualified engineers will be onsite to carry out the installation. All work can be completed in house, including the positioning and connection of the heat pump, buffer tank and heat pump cylinder, connection of the heating controls and final commissioning of the system. Upon completion you will be provided with a full handover pack.

We will complete the Boiler Upgrade Scheme Voucher Application Form for your installation and submit it to Ofgem, who will then contact you to confirm the installation has been completed.

How do Air Source Heat pumps work?

Air Source Heat Pumps and Ground Source Heat Pumps work by extracting latent heat energy from the environment (either from the atmosphere, from under the ground or from a lake or river) to heat a property and produce hot water. The environment around us absorbs and stores heat energy from the sun. This heat energy is stored at low temperature and in order to make it useful for heating purposes the temperature of this stored heat energy needs to be increased.

In a Ground Source, or Ground to Water, Heat Pump for example, an array of underground pipes, containing a water and glycol based antifreeze mixture, known as brine, absorbs heat from the ground, (at a depth of approximately 1m – 1.2m this heat energy is at a fairly constant temperature of 10 – 12oC). The brine then passes through a heat exchanger within the heat pump and transfers its captured heat energy to a refrigerant gas, which has a low enough boiling point so that the heat energy stored in the brine causes it to evaporate. This evaporated gas then passes into a compressor; compressing the refrigerant gas, causing the temperature to increase.

The compressed gas then passes through another heat exchanger, known as a condenser, where the stored, higher temperature heat energy is transferred into the property to provide heating and domestic hot water. As the refrigerant gas gives up its stored heat energy, it condenses back into a liquid and begins its circuit back around the heat pump.

The compressor and circulation pumps within the heat pump require an electrical supply, but because most of the heat generated by the heat pump is free heat energy drawn from the environment, heat pumps are typically 350% – 450% efficient, so for every 1 Kilowatt of electricity used, the heat pump will generate 3.5 – 4.5 Kilowatts of heat.

In order to achieve these levels of efficiency and maintain low running costs, heat pumps are best suited to well insulated, new build properties or properties that have been renovated to new build standards and they need to produce flow temperatures as low as possible; typically, between 35oC and 45oC. Because of this, heat pump installations must be designed in unison with the heat emitters, whether they are radiators or underfloor heating.

The advantages of all heat pumps is that they have minimal maintenance requirements, long service lives and when installed correctly will provide very cost effective heating for years to come.

How an Air source heat pump supplies your home

Air Source, or Air to Water, Heat Pumps work by drawing heat energy from the atmosphere. Although the air temperature is more prone to fluctuation, Air Source Heat Pumps are still highly efficient and will provide 100% of the heat most properties require. For larger properties, it is possible to integrate a heat pump with a conventional heating system to produce a ‘bivalent’ system.

The advantages of Air Source Heat Pumps are that they are quick, easy and therefore relatively cost effective to install and that they can be installed in properties that have minimal adjoining land.
