Canary Wharf - one of the world's foremost business districts - is at the forefront of the green technology revolution.
The Financial Services Authority, which has its headquarters in the district, is using green energy in a bid to cut energy bills and be kind to the environment.
Heat pumps are being installed to provide hot water for all of the building's washrooms, across 14 floors.
Stiebel Eltron, the company that manufactures the heat pumps, is now working on a programme to equip the entire building with the technology and has revealed that neighbouring organisations are so impressed they are considering following suit.

Neil Jimpson of Stiebel Eltron explained how the technology works: "Each floor of the building was supplied with one air source heat pump on each of the 14 floors to provide hot water. The heat pumps are housed in a chiller plant room, which provide air conditioning to cool the building. The heat pumps installed in these rooms recycle the latent heat generated, to supply 300 litres of hot water for the washrooms."

Neil added: "Prior to this work starting, we installed a heat pump and monitored how much energy was saved. The result was an incredible four times less energy than conventional heating methods."

Malcom Pryme of Ward Contract Services Ltd, which is installing the technology, said "We are delighted with the unit due to its ease of installation and performance. Stiebel Eltron has provided a lot of support and we are pleased to be working in partnership with them."

Mark McManus, managing director of Stiebel Eltron, said: "This is a great project and we are delighted to have provided the latest in green energy into such a high profile, well known building."

"Green energy is the future and there are lots of grants and tax breaks available to homeowners and the public and private sector to convert their properties to green energy."

Heat pumps extract energy from the air or ground to produce heat for a building. Immediately, the property is no longer at the mercy of volatile oil and gas prices meaning the heat pump can pay for itself within a matter of years. The carbon saving impact is considerable.
Heat production is responsible for half of the energy consumed in the UK and half of the carbon emissions. Experts describe heat energy as the 'sleeping giant' of climate change action.

A thriving heritage centre that has risen from the ashes of an abandoned Welsh village is combining traditional architecture with the latest green technology.
Nant Gwrtheyrn, near Pwllhelii in North Wales has been transformed from a derelict mining village into a stunning complex dedicated to learning Welsh.

The complex, situated in a historic coastline landscape that dates back to the Iron Age, is using the latest heat pump and solar technology to provide heating and hot water.
The developments have been carried out over several phases, following a major fund-raising drive and include a heritage and activity centre, a cafe, living accommodation, holiday cottages and a wedding venue.

Steve Love of Eco-Energy Services who installed the technology, said: "This is an ancient site and the buildings are listed so we were presented with a challenge when installing the heat pumps, solar panels and underfloor heating."

Jim O'Rourke, spokesman for Nant Gwrtheyrn, said: "We are very pleased with the way in which new green technologies have enabled us as a charity to save money on our heating costs, whilst also contributing to a reduction in the use of fossil fuels and providing more comfort for our guests."

"We have developed 4* accommodation for up to 80 guests but can sometimes cater for quite small groups of only 10 so we needed to be careful in the way we manage the energy use. We need to ensure we use the most efficient heat source in relation to the demand for heating or hot water at a particular time. We considered numerous options and heat pumps have proved to be a first class solution."

The heat pumps were manufactured by Stiebel Eltron and its UK managing director Mark McManus, said: "This is an incredible project and we are delighted to have provided the latest in green energy into a development that is so steeped in history."

"Green energy is the future and there are lots of grants and tax breaks available to homeowners and the public and private sector to convert their properties to green energy."

"Meeting the UK's 2020 and 2050 carbon reduction targets will require a major contribution from heat. Because 54% of heat use is in people's homes, 30% is industrial and 16% comes from commercial, public sector - we all have a responsibility to find greener alternatives.""Heat pumps are right at the forefront of green energy technology and this is a massive growth industry," he said. "Essentially heat pumps extract energy from the air or ground to produce heating for a property."

"Immediately, the property is no longer at the mercy of volatile oil and gas prices mean the heat pump can pay for itself within a matter of years. The carbon saving impact is considerable. Heating is responsible for almost half of UK energy use and carbon emissions, therefore heat pumps have a vital role in making the UK greener."

The carbon saving impact of using heat pumps rather than more conventional forms of heating is considerable.
Heat production is responsible for half of the energy consumed in the UK and half of the carbon emissions. Experts describe heat energy as the 'sleeping giant' of climate change action.

A Scottish Youth Hostel on the Isle of Arran has integrated the latest green technology as part of an exclusive refurbishment project.
The 700 m2 Lochranza Youth Hostel, has been equipped with two Stiebel Eltron LWA 252 air source heat pumps. The units extract energy from the warm, moist air and use it to heat the hostel's domestic hot water.

The 58 bed hostel has benefited in two ways because of the Stiebel Eltron green technology. The warm, moist air removed from the bedrooms and bathrooms has resulted in much cleaner, comfortable accommodation. Also, the cost of energy used within the hostel has significantly dropped as the heat pumps run much more efficiently than its previous system.
The Stiebel Eltron heat recovery pumps were put in as part of a full scale mechanical refurbishment, which also included a rainwater harvesting system and replacement domestic services system. They were installed by Glasgow based renewable energy design and installation specialist MMAXX.

Neil McFarlane, project manager of MMAXX, which installed the green technology said:
"The Stiebel Eltron heat recovery pumps were the best option for the hostel. We were able to install them within the building due to their low sound emissions. The hostel was also able to gain a grant for the work, due to the high performance of the products being installed. We have worked with Stiebel Eltron for a number of years now and we use their products for their high efficiency and dependability."

Maurice Macklin, Scottish sales director for Stiebel Eltron highlighted the importance of shared accommodation using green technology.
"Lochranza Youth Hostel realised the benefits, financially and environmentally, of installing green technology," he said. "Heat pumps will play a vital role in making the UK greener and by installing a unit it can not only reduce carbon emissions but as shown here, can recycle the latent air that is already within the building. We expect to see demand for heat pumps continue to increase due to the introduction of the Government's Renewable Heat Incentive and Feed-In-Tarrifs (see background). This means you are able to gain significant financial return on any green energy investment."
Stiebel Eltron can undertake a free energy efficiency report for any property in Scotland. This report will examine the heat demands of your building and detail a set of recommendations of how best to go green.

Renewable energy heating products are right at the forefront of the Government's green energy revolution. With heating responsible for 70% of UK energy use - and Carbon emissions - finding green alternatives to oil and gas heating is critical. The pressure to achieve this is ramped up by the UK's target to generate 20% of UK energy coming from renewable sources by 2020.

Community project turns Thames green a highly innovative renewable energy heating system, which converts energy from the River Thames into heat, is being unveiled by a community river project. The Hermitage River Project is a community programme near Tower Bridge. It is made up of riverboats, many of which are over 200 years old, and a community centre.
