Renewable Energy

Carillion Energy Services provide renewable energy solutions for the commercial, residential and public sector offering Solar Thermal, Photovoltaic, Ground Source and Air Source Heat Pump systems.

With coverage across the UK and Ireland, our highly trained and experienced team will work with you to help with system design, project management and installation and will ensure reliable and effective alternative energy solutions.

Not only do we offer balanced, sound advice, we also offer training for the end user such as schools and educational facilities to make sure you get the most from your investment.

Solar Thermal

Solar Thermal heating systems are one of the most cost effective and environmentally friendly renewable energy resources available making it the most popular form of solar energy used in the UK.

A Solar Thermal hot water system heats water for domestic use by harnessing the infrared energy present in daylight. This abundant source of free energy quickly heats up fluid in a solar panel (also called a solar collector).

A small pump circulates this fluid through a coil in the hot water cylinder and heats up the water. During the winter months there is not enough energy available to fully heat the water so the existing heat source (boiler or immersion heater) automatically tops up the stored water temperature.

Photovoltaic

Solar Photovoltaic systems generate electricity in a clean, quiet and renewable way. Photovoltaic panels come in a variety of shapes and colours, ranging from grey 'solar tiles' that look like roof tiles to panels and transparent cells that you can use on conservatories and glass, the variety of applications for solar electric are numerous.

Carillion Energy Services have designed and installed Photovoltaic systems on a wide range of buildings including residential properties, commercial buildings, schools and swimming pools and can provide professional advice on the most suitable solar panels for your project.

Photovoltaic systems use sunlight to create electricity. The system uses cells which can be mounted on or built in to existing or new buildings and can be used in both stand alone and grid-connected systems. In the UK the most common type of Photovoltaic system installed is one that is connected to the grid system, this allows you to use the electricity at its point of generation or sell the electricity back to the grid – so you can use renewable energy and make money in the process.

Heat Pumps

Heat Pumps are an excellent way to heat a building and provide hot water whilst making a massive reduction in the buildings carbon output. Significant cost savings can also be achieved by reducing fuel consumption.

Heat Pumps use similar technology to that employed in domestic refrigerators or freezers, but in reverse. They extract free low grade energy from sources such as the earth, water or air and convert it into high grade heat energy. There are two types available; Ground Source Heat Pumps and Air Source Heat Pumps.

We are experienced consultants will ensure that the most appropriate solution is used to match the needs of the project.

Ground source heat pumps transfer heat from the ground and use it to heat buildings through systems such as under floor heating, radiators and in some cases, pre-heating hot water. The system provides a total heating solution throughout the year for both homes and commercial premises whilst giving real cost savings as well as significant reductions in carbon emissions when compared to conventional systems.

A Ground Source Heat Pump consists of three key elements –

• The Ground Loop – This is comprised of pipe buried in the ground which is filled with a mixture of water and antifreeze which is then pumped around the pipe absorbing heat from the ground.
• A Heat Pump – The system works in the same way as a refrigerator but in reverse so rather than extracting heat from the inside (i.e keeping your food cool), the heat pump extracts heat from the ground and uses it to heat your home.
• Heat Distribution System - This consists of under floor heating or radiators for space heating and some cases water storage for hot water supply.
