New door curtains cut energy use by 72%
Southend University Hospital A&E Department have installed new air source heat pump air curtains which have made significant savings in terms of energy use and carbon emissions.
The air curtain limits heat loss through the door opening and enhances the efficiency of the air conditioning system which gives energy savings of up to 72% compared to electric air curtains.
How do ASHP’s work?
Air Source Heat Pumps extract heat from the outside air, which is then used to deliver heat to your premises via a ducted air or wet system. Acknowledged as a renewable technology, air source heat pump units are situated on the roof or ground. Heat pumps offer the highest energy efficiency possible making them ideal for schools, universities and hospitals.
Southend Hospital Energy Manager, Manoj Chohan, said “before the project could start, we had to justify the funding and put together a business case showing cost effectiveness, how it would save energy and reduce carbon. For just the replacement of the doors in the A&E department we estimated a savings of 20 tonnes of C02 (carbon dioxide) and we would achieve payback in 3 years”.
