| HS{Lord Ernest Hives - Chair}/TMW X 4006 To Mr. Warwick from Da.{Bernard Day - Chassis Design} Dal7/CB17.12.20. X.4200 X.4006 RE. EXHAUST HEATERS. As this question is likely to be one of interest in the immediate future we have got two samples of exhaust heater, if you can find a means of trying them. The first one "Argen" appears to be rather a good idea, in as much as hot air is drawn through the radiator system instead of exhaust gas being forced through it. Unfortunately it means an alteration to the silencer, and apparently the addition of a fair amount of weight, but we think the principal is distinctly worth trying. The second one is a "Temme" which is of a much more ordinary construction, but we think might be tried at a suitable opportunity. Both these heaters are in my office if you would kindly send someone across to bring them over.
