Devon NHS Trust embraces heat pumps on the road to Net Zero
The Devon Partnership NHS Trust is cutting its energy consumption and carbon footprint by upgrading the heating and cooling system at Langdon Hospital in Dawlish.
M
itsubishi Electric e-Series heat pump units have been installed at the Langdon Hospital in Dawlish, which
serves the Dewnans Centre – a medium secure facility based near the seaside town of Dawlish in southwest England providing accommodation for men with mental health needs.
While living on a site located less than a mile
from the sea can be good for the mind and benefi cial to patients at the Dewnans Centre, the Trust needed a solution that could cope with saline in the atmosphere, and able to help the centre improve energy effi ciency. Mitsubishi Electric provided Langdon Hospital
with three e-Series EAHV1500 YCL modular heat pump units for underfl oor heating in the winter months, and two e-Series EACV1800 YCL modular chillers for underfl oor cooling in the summer months. The units were connected using the e-Series unique internal header, which removes the need for separate piping connections, valves and commissioning, and reduces cost and installation time.
“Our old system was not suited to building
a greener future. The energy consumption and costs for the old chillers were increasing signifi cantly year on year. We’ve already seen an
overall reduction in energy consumption with our new sustainable system, so we are very hopeful that in addition to reducing carbon emissions, we will also be reducing our running costs,” explained Collette Germon, Sustainability and Energy manager for the Trust.
Mitsubishi Electric conducted an initial front- end engineering design to assess the existing M&E infrastructure and its requirements. This helped highlight any issues and provide initial solutions. Paul Lewis, Turnkey Contracts Manager at Mitsubishi Electric, explained: “I had the chance to visit the site with Rod, Langdon Hospital’s Estates Offi cer, and together we looked at the diff erent options available to fi nd the most suitable and sustainable solution. This was an end-to-end

project for us, encompassing everything including design, equipment selection, and replacement of mechanical and electrical items associated with that plant. It was great to be able to support the facility on its road to Net Zero.” Another important consideration for Langdon Hospital when choosing which manufacturer to work with was the safety of patients and contractor staff , given the sensitivities of a medium security facility. Rod Butler, Estates Offi cer, Langdon Hospital, said: “Mitsubishi Electric completely adhered to the strict site-specifi c rules. They paid special attention to how they interacted with patients and restricted working activities and managed the movement of both plant and equipment when necessary.”
