What Are Transpired Solar Collectors and How Can They Help Your Business?

Transpired Solar Collectors (TSCs) are a very simple and effective way to harness energy from the sun to heat a property. The technology is relatively new to the European and UK markets but has seen success over the last 20 years across USA and Canada.

Transpired Solar Collectors are made from perforated pre-finished steel and are installed as a skin onto an existing or new building. The skin creates a cavity with the wall which is then used to draw the sun’s radiant energy into the building.

Installing transpired solar collectors can save up to 50% of space heating costs for commercial properties including, but not limited to, warehouses, hotels, office buildings, multi-residential buildings and schools.

How does a Transpired Solar Collector work?

Transpired Solar Collector’s draw the ambient air warmed by the sun through the perforations in the skins surface into the cavity. The warm air then flows to the top of the building and is circulated using mechanical ventilation. This air is then fed either directly into the building or into a HVAC unit to pre-heat the main heating system.

What are the benefits of Transpired Solar Collectors?

Transpired Solar Collectors have been developed during the last twenty years and are designed to pre-heat fresh air and improve indoor air quality. Installing TSCs can reduce fuel bills by up to 50% and they benefit from a fast payback of up to 3 to 12 years depending on the fuel replacement.

TSCs are up to 80% efficient, maintenance free and have a 30 year life span. Properties featuring TSCs will also benefit from a massive CO2 reduction.

What should you consider when installing Transpired Solar Collectors?

Before installing TSCs you must consider the suitability of location and building, as well as the area of collector required to make the installation viable. The possible energy savings and payback period should also be considered before installation begins.


Air Source Heat Pumps (ASHPs) can be used to provide heating and hot water and can absorb heat from the air in temperatures as low as -15o C. Unlike conventional boilers, ASHPs deliver heat at lower temperatures over longer periods of time and are available in two systems; air-to-water and air-to-air.

How Air Source Heat Pumps Work?

ASHPs transport the heat from the air outside into a fluid that moves through a compressor which increases its temperature. The high temperature generated is then used to heat the property.

Air-to-water systems generate heat via a wet central heating system, whilst air-to-air systems circulate warm air through fans. Air-to-air systems are more suited to heat a property and are unlikely to provide hot water as well.

What Are The Benefits Of Air Source Heat Pumps?

ASHPs contribute to making a property more energy efficient, which in turn could lower energy bills and the properties carbon emissions. Typical installation costs are between 6,000 and 10,000 pounds, and running costs depend on the size of the property and how well insulated it is. ASHPs are powered by electricity so wont negate the need for fuel bills, however you will save on the fuel you are replacing.

Government Incentives For Air Source Heat Pumps

After installing an ASHP you may be able to receive payments for the heat you generate through the governments Renewable Heat Incentive (RHI) launching in summer 2013. Installation costs for any systems installed after 1st August 2011 may also receive a one off grant through the Renewable Heat Premium Payment Scheme (available until the RHI is introduced to domestic customers).

Green Deal Launched 28th January 2013

This week the Government launched its new renewable energy initiative, The Green Deal.

Designed to encourage home owners to modify their properties to increase their energy performance, The Green Deal is hyped as the next big thing. It officially launched on Monday 28th January 2013, and has already featured on the BBC and in the Guardian.

Under the Green Deal, properties can be assessed for ‘measures’ to be installed and financed by a government endorsed loan. The loan is attached to the customer’s energy bills and stays with the property, so should the customer decide to move the outstanding balance can either be paid off during the transaction or transferred to the new property owner.

To qualify for Green Deal the proposed results of the improvements must outweigh the costs, something more regularly referred to as ‘The Golden Rule’. The Golden Rule is there to ensure a customer doesn’t end up paying more than they did before the measures were installed, however it doesn’t guarantee savings. Green Deal Assessments are based on assumptions and some customers may only break even.

There are 45 measures available to help improve properties energy efficiency, and these include everything from small improvements like boiler jackets and draft excluders, to the larger installations of wind turbines and solar panels.

The process to complete a Green Deal Plan is fairly straightforward:-

1.Arrange an assessment with an approved Green Deal Provider.

2.A survey is completed on your property by an approved Green Deal Assessor, who then reports on the measures that could be installed to increase your current energy efficiency.

3.The Provider will make an application for finance, and an approved Green Deal Installer will install the measures required.

4.The customer repays the finance through their current energy bills.
