High temperature insulation of engine hoses
My (230V AC) electric engine prewarmer had to be installed on the coolant hose going from the cabin's heating core back to the engine block, wouldn't fit anywhere else.
How beneficial it would be to insulate the hoses going between the cabin and the engine? I am thinking about how much heat they radiate when the engine bay's temperature is below freezing. The insulation may allow slightly faster heating of the engine, or higher prewarming temperature.
What kind of insulation would be best for this? It must withstand relatively high temperatures from the engine block, but also not be affected by low temperature nor moisture.
