Dear Sirs, re:- "Hercule" Thermostat. We are in receipt of your letter of the 12th instant, and desire to advise you that our "Hercule" thermostat can be supplied to operate between 10°C and 100°C, as it is possible for us to vary the special medium which operates the piston mechanism. We recommend the radiator shutters to commence opening at about 50°C and to be fully opened about 70°C, but we can supply thermostats to open at the higher range you suggest. We can supply a thermostat to operate at 25°C and with regard to dimensions, these can be confined to occupy a very small space. We shall be obliged if you will advise us as to the space at your disposal in which the thermostat can be operated. Assuring you of our immediate attention at all times. We are, dear Sirs, Yours faithfully, GALLAY RADIATOR CO. LTD. M.L-T. Delaney p. | ||
