Mitsubishi Air Source Heat Pump

Originally founded in 1921, the company known today as Mitsubishi Electric has almost 100 years of experience in providing reliable, high-quality products to both corporate clients and general consumers all over the world. For generations Mitsubishi have been leaders in the world of energy products.
Since 2007 these industry giants have dedicated their craft to revolutionsing the world of renewable heat with their Ecodan air source heat pumps scotland.
Three years later in 2010 the company continued to innovate with the launch of their commercial Ecodan systems.
These systems are specifically designed to work effectively in Britain’s climate as a way to diminish climate change and reduce carbon emissions across the UK.
How a Mitsubishi Ecodan Heat Pump can reduce your Carbon Footprint
Energy is one of our greatest commodities that keeps Scotland’s economy ticking over, we use it for a plethora of applications; energy heats our homes, schools hospitals and fuels our businesses.
However, as we know by now with energy production comes toxic greenhouse gases, energy supply counts for approximately 30% of all greenhouse emissions which contributes to global warming and climate change.
Carbon dioxide is the most substantial greenhouse gas that is released by human activity, which comes from the burning of fossil fuels such as coal, oil and natural gas. Thankfully there are plans in place by the Scottish government to reduce these emissions and have 30% of Scottish energy consumption powered by renewable energy by 2020. Domestic heat pumps and commercial heat pumps are a great way to combat climate change.

Commercial Mitsubishi Air Source Heat Pumps
It’s is estimated that 40% of carbon emissions come from commercial heating and cooling, so it’s no wonder businesses are looking for new ways to heat their premises whilst also reaping long term benefits. One way companies can work to reduce Co2 emissions in Scotland is to harness one of the planet’s greatest carbon neutral sources available all around us through ground and air sourced energy.
A Mitsubishi Ecodan ground source heat pump acts in the same way a fridge does, it absorbs heat from the grown or water below then raises the temperature to be used in water heating or space heating.
Mistubishi Ecodan ground source heat pumps can provide water temperatures up to 65 degrees Celsius from ground and water temperatures from as low as -5 degrees Celsius.
The Mitsubishi Ecodan ground source heat pump is recommended for medium to large commercial premises. It can draw heat from places such as river water or waste processing which can then be transformed into usable heat.

Here at Heat Pumps Scotland, we are registered Ecodan installers and will provide your commercial heat pump expertly. The Ecodan uses heat pump technology to produce low-carbon heating and hot water. This system is award winning that is ideal as a replacement for traditional heating systems.
Benefits of Heatpumps - Mitsubishi Ecodan Ground Source Heat Pumps
- Helps achieve renewable energy targets
- Capable of reducing running costs and CO2 emissions
- Easy to design, install and maintain
- Fully scalable and can work independently or in conjunction with other systems
- Optimised systems up to to 960kW
- Little maintenance required.
Ground source heat pumps extract heat from the ground through pipes buried in the soil. The heat can be transferred to heat radiators and under-floor systems, water and hot air systems all from a completely natural source.
Although there is some electricity needed to run ground source heat pumps, meaning they have some environmental impact they are still much preferred to conventional heating systems as the energy they extract from the ground is constantly being renewed naturally. Did you know that for every 1kW of electricity fed into an Ecodan heat pump, you can produce up to 3kW of consumable energy? This makes the system highly efficient and can offer great savings when compared to traditional heating systems.
Commercial heat pumps are a wonderful innovation that can heat schools, office blocks and even communities. However, the greatest benefit of these systems is their entirely renewable nature which provides effective heating in Scotland with little damage to the environment.
Benefits of Heat pumps – Mitsubishi Ecodan Air Source Heat Pumps
- Helps achieve renewable energy targets
- Capable of reducing running costs and CO2 emissions
- Easy to design, install and maintain
- Fully scalable and can work independently or in conjunction with other systems
- Optimised systems from 4kW to 688kW
Much like a typical ground source heat pump an Ecodan air source heat pump works in a similar way. The system absorbs cool air from its surroundings and raises it to a high enough temperature than be used to heat the premises or the water in the radiators and taps.
Ecodan air source heat pumps can provide water temperatures up to 60 degrees Celsius from outside temperatures as low as -25 degrees Celsius. This is a great benefit as our customers will know their systems can produce heat even in the most bitter of Scottish winters! We are expert Ecodan installers and our skilled team provide commercial heat pumps for all your corporate needs.
Non – Domestic Renewable Heat Incentive

The Non-Domestic Renewable Heat Incentive Scotland (RHI) is a Department of Energy and Climate Change (DECC) and Government approved scheme that provides financial incentives to promote the installations of renewable heat throughout The UK. Once your renewable heat system is installed your business will receive quarterly payments for every kilowatt hour produced for 20 years. After March 25th 2016 all heat pumps installed must meet a minimum performance standard and come with an EU energy label in order to be eligible for the RHI.
Savings from Commercial Heat Pumps Scotland
Not only will your business receive an income from the RHI, but great savings can be made on top of this. By installing a ground or air source heat pump your businesses energy bills will be reduced, although some electricity is still used as the system is powered by electricity you will save by replacing the current fuel your business uses with that obtained from natural, completely free, source.
Savings will also be made due to the efficiency of new heating systems. It is likely your current system is not heating your building to its full potential. You will have lower running costs thanks to the installation of an efficient system. Using your heating system correctly will not only benefit the planet, but your bank account too.
Proper control of the thermostat will allow you to make savings. A useful tip is to set the temperature slightly lower, but have the heating system come on a few hours early. This will allow your workers to still feel comfortable but reduce wasted energy.
Are Commercial Heat Pumps Efficient?
Heat pumps are especially efficient, providing huge savings if your company is heated by oil or LPG which is a further benefit of heat pumps.
- Air Source Heat Pump – 290% efficiency
- Ground Source Heat Pump – 320% efficiency
- Oil – 87% efficiency
- LPG -90% efficiency
Depending on the size and nature of your building, heat pump systems will very in cost but there is no doubt there are significant savings to be made as heat pumps deliver around 3 to 4 kWh of energy for every 1 kWh of electricity used to power it, which means they are 300 to 400% more efficient than electric heating. With all these benefits and the government targets for carbon emissions still a mile away, can businesses continue to be picky about their heating systems? Is it time your business caught on to this trend for 2016?
