Our next station in our Jerusalem Houses From Within guided tour of Shaare Zedek Medical Center was the heating/cooling center which controls the air conditioning and heating and water systems of the big hospital.
The people who keep everything working well are so proud, they hang hospital flags among the boilers and pipes.
The little signs says that ear protection is a must.
Indeed, the machines were very noisy down there.
The grey giant is a steam boiler.
These days, it is heated by electricity.
Should the hospital be cut off from its water supply by war or natural disaster, there are big reserve pools that hold enough water for 72 hours.
They are cleaned once a year.
The all-important Control Room.
There is a back-up for every emergency break-down that might happen.
If something goes wrong with a machine or a computer, e-mails and SMSs go out immediately to call in the appropriate technician and man in charge, night or day, Shabbat or weekday.
