Heating

The hall is heated by 'radiators' embedded in the walls, with fans to blow air over them.

Initially I was told they were part of a central heating system for the whole hospital site, and so Cripps had no independent control. I presumed the radiators were iron pipes with hot water flowing through them. Andy (Salsa) tells me they are electric storage heaters, and there is a switch for each of them, hidden inside a small hinged panel beside each of them. I do not know if the system has been changed, or I was just being fobbed-off through ignorance.

Strictly they will not really be 'radiating' much, except to make the walls warm. They will heat the air by direct contact as it blows over the pipes filled with hot water.

There are switches to turn the fans 'Off - Low - High'.

Even with the fans off, air within the 'radiator' will be heated and rise, so that it will flow in through the lower grille and the out through the upper grille, simply because hot air rises. (Thermal convection)

One of the Cripps staff has also turned the heaters off or on last year. I thought it was Hayley, but she may not remember it.
