2. The main issues
• Meet Carbon Reduction Targets
• Reducing energy costs
• Life Cycle costs
• Providing innovation in design and operation
• Save space in plantroom
• Provide value for money
3. Types of Boilerplant
• Central Steam
• Central MTHW
• Central Biofuel Steam
• Central Biofuel MTHW
• Decentralised LTHW
7. Traditional Steam Plantroom
Vents from safety valves
LTHW Water circuits
Flash loss
from vent
DHW Heat Exchanger
Condensate pump Potential for Legionella
problems
8. Issues with traditional steam plantroom design
• Flash steam losses
• Waterhammer in calorifiers
• Duty / standby PRV sets
• Cost of separate condensate pump and vent
• Problems with Legionella with storage cylinder
• Maintenance issues with shell and tube units
• Usually supplied as loose parts making costing and
installation expensive
10. The Modern Low Carbon Plantroom
Boiler pressure steam No PRV or condensate pump required
DHW
LTHW
LTHW
DHW Variable speed drive
pump skid
100% sub-cooled condensate return
11. Modern Steam Plantroom
• Can be connected directly to high pressure steam main
• 100% sub-cooled condensate returned to boiler
• Greatly reduced steam consumption
• No vents required
• No condensate pump required
• No storage cylinders required
• Legionella problems eliminated
• Quick installation
• Variable speed pumps supplied on skid
• No withdrawal distance on exchangers
• Much smaller plantroom required
• Space can be used for patient areas

15. Conclusions
All systems designed to help Hospitals meet stringent CO2
Reductions
Systems will deliver large energy reductions
All systems are packaged for ease of installation
All systems are well planned and project managed
Various finance options available
In most cases plantroom space can be given back to patient
care
Hospitals can now have the most energy efficient plant
available
