| Hotel de France. Chateauroux. Indre. x1860 To H.R./Rm.{William Robotham - Chief Engineer} From G.W.H. 18. G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 1V2 We have fitted the radiator thermostat made by the Packless Gland Co. The temperature at which the radiator shutters open is the same as previous ie. 75°C. We have not so far been able to detect any difference between the standard thermostat and the Packless. RADIATOR With the hot weather we are experiencing. we have not much to spare with the radiator cooling efficiency. The water temperature is reaching 94°C, Oil 90°C with an air temperature of 31°C = 87 3/5 Fah. G.W.H. | ||
