Air Source Heat Pumps
How They Work?
The heat exchanger contains a special fluid that has a very low boiling point. This allows it to absorb heat from the outside air, even at lower temperatures. This fluid is then passed through a compressor which increases its temperature. The fluid is then passed through the heating circuit which releases the heat to be used in the building. The heat produced from a heat pump is at a lower temperature than you will find with traditional oil and gas boilers which makes it ideal for underfloor heating.
Air source heat pump systems can offer much lower running costs compared to oil, LPG and electric boilers. In addition to saving money on your bills you can also receive payments from the domestic renewable heat incentive.
Heat Pumps with Korrie
Korrie Renewables are the leading the way in the design and installation of heat pump systems in the North of Scotland. Before we provide a quote for a heat pump system, Korrie will conduct a full bespoke design for your property. Our local engineers are fully trained in the latest technology and will treat each property like their own home!
We will present you with suitable options and walk you through the best heating system to suit you and your home. If an air source system is not suitable (eg if its a poorly insulated property) we will offer an alternative technology such as biomass. With every quote Korrie will provide an estimated running cost and what you can expect to receive from current incentives.
It is our goal to give all our clients an honest and trustworthy quote for a system designed for you! Our confidence in heat pump systems are backed up with over 500 sucessfull heat pump installations across the north of Scotland.
Fuel Cost Savings
Depending on the fabric of your home, heat pump systems can provide fuel cost savings against conventional systems such as Gas (mains and LPG), Oil boilers, Electric (boilers and storage heaters) and solid fuels such as coal. The table below gives an indication of what savings can be achieved on an average four bedroom semi-detached home. Please note that every home is different, please contact us for a free consultation to see how much you can save.

Renewable Heat Incentive
In addition to receiving lower fuel bills, self build and heating replacements installation a heat pump system will receive payment through the Renewable Heat Incentive also know as RHI. These are payments made by the Government to promote renewable heating systems. Payments are fixed and are paid out every quarter for a period of 7 years. The payment you will receive will depend on the outcome of a Green Deal Assessment. The larger the heat load of the house (bigger and less insulation), the more your payments will be. An average 4 bedroom house can expect yearly payments of around £905 per year.
How Much Does A Heat Pump Cost?
The cost of a heat pump system can vary depending on a wide range of factors. Systems can cost from £6,000 to over £10,000. For more information please contact us to arrange a free consultation with one of our engineers. In addition to our heat pumps we can also install new central heating systems, underfloor heating, solar PV arrays and solar thermal systems. These additional technologies can improve and enhance your property.
To help with the capital costs of installing a renewable heating system, the Energy Saving Trust offers Interest Free Loans up to a value of £10,000. For more information on these loans, please visit the Energy Saving Trust Website here.
Korrie can install...
The Ecodan heat pump range is suitable for small to large applications. Using proven heat pump technology to deliver effective, low carbon heating and hot water, Mitsubishi Electric’s award winning Ecodan systems provide a simple, renewable solution that rivals traditional heating systems.
These MCS accredited heat pumps are the first choice for local housing associations with hundreds being installed by Korrie over the last three years.
Korrie can offer a wide range of additional services which can enhance and improve a heat pumps system. The installation or upgrade of a central heating system or underfloor heating system can allow you to lower the flow temperature of your heat pump system. This can increase efficiency and lower your running costs. The addition of solar panels can provide you with free hot water using solar thermal or free electricity using solar PV panels. Both solar systems work excellently with heat pump systems and will lower its running costs.
