PROJECT
HEATHER HOUSE CNU, ST MARY’S HEALTH CAMPUS, CORK
TWIN HIDROS AIR-TO-WATER HEAT PUMPS INSTALLED AT ST MARY’S COMMUNITY NURSING UNIT, CORK… HVAC SUPPLIER
E uro Gas was awarded the order for the supply of the mechanical services equipment for Heather House, a 60-bed community nursing unit (CNU) extension at St Mary’s healthcare campus, Cork. In addition to 60-ensuite bedrooms, the extension also comprised a reception area and day rooms. The existing CNU remained operational throughout the scheme, which was expedited as part of the HSE’s emergency Covid-19 works. SCOPE OF DELIVERY Euro Gas provided the mechanical services equipment across the entire project. The heating system is fed by two LHA Hidros high efficiency air-to-water
heat pumps which have been specifically designed for applications where maximum heating efficiency is required. Optimised on heating mode, the heat pumps are able to produce water up to 60°C and can operate down to -20°C ambient temperature. Hot water produced is then stored in a Cordivari Puffer heating water buffer tank. Providing support and redundancy for the heat pump are two Potterton Sirius Three WH 110kW wall hung commercial gas boilers. Compact and lightweight, Sirius Three WH condensing boilers offer a market- leading modulation ratio of up to 9:1 and come with weather compensation as standard, ensuring high seasonal
efficiency all year round. Two Lochinvar EcoShield Fully
Condensing Gas-Fired Water Heaters (model: SHW146-410CE) satisfy the domestic hot water requirements. With efficiencies of up to 96.45% and NOx emissions as low as 32mg/kWh, EcoShield Water Heaters can reduce energy consumption and carbon emissions. Further reducing their overall gas consumption, a Cordivari Vaso Inerziale buffer provides the EcoShield Water Heaters with water preheated by the air-source heat pumps. A high efficiency Cipriani Plate Heat Exchanger provides the hydraulic separation between the technical and domestic water. SpiroVent deaerators from SpiroTech
