Ground source heat pump for new build apartments, Brighton

Ground source heat pump with boreholes and heat recovery

Heat pump makes new apartments fit for the 21st Century

Ocean heights apartments use Stiebel Eltron heat pump

‘Ocean Heights’ in Roedean overlooks Brighton Marina, and is being built by Brighton Construction. It has commissioned renewable energy specialist Stiebel Eltron to install an innovative ground source heat pump. The heat pump generates the heating and hot water for all seven apartments.

Brighton Construction director Jerry Vasse, said Ocean Heights’ is a terrific example of how buildings can become greener. “It was vital to us that we built a set of apartments fit for the 21st century,” he said. “That means that they had to be energy efficient and not waste energy. Equally we wanted them to use the latest forms of green energy. We are passionate about sustainability and being environmentally friendly.”  


Stiebel Eltron South East specification manager Neil Jimpson said the heat pumps in ‘Ocean Heights’ would help save residents money on energy bills. “The beauty of Ocean Heights’ heat pump is that it will pay for itself within a matter of years in saved energy bills,” he said. “Critically this means the apartment owners will not be at the mercy of volatile oil and gas prices as well as saving 15.4 tonnes in CO2 emissions. But heat pumps are very much the future because they show there is a green alternative. When you consider heating is responsible for almost half of UK energy use and carbon emissions you can see how important heat pumps are in helping the UK go green.”

Ocean Heights architect Scott Theobold of Bold Architecture Design said the development deployed the latest eco design methods. “Sustainability is at the heart of the Ocean Heights scheme,’ he said. “The ground source heat pumps supply under floor heating and hot water to each flat via 100m deep bore holes. No gas boilers are required and the heating is also supplemented by heat recovery units. These units extract air from bathrooms and kitchens and heat up incoming fresh air to room temperature. In addition, rainwater is collected from roofs and hard standing areas and stored in a tank for use in outside taps for maintaining the gardens. WC flushes will also be supplied using recycled water.

“We’ve also used ICF, polystyrene formwork for in-situ concrete, construction which gives higher levels of insulation and air tightness to the building. The south facing orientation of the development helps heating too as in the winter the large areas of glazing capture sunlight and benefit from solar gains.”
