I have recently renovated the basement. I made a mistake of going with cheapest contractor who doesn't seem to care much about safety. I have old style radiator heater on 1st and 2nd floor and pipes are running in basement as shown in image below. I have also replaced my old steam boiler to get a new powerful (146k BTU) boiler. Pipes are going through newly installed drywall and also going up from behind the dry wall.
Should I be worried about fire in case pipe gets too hot? I am not sure how hot these steam pipe will get in winter when boiler runs for hours. Also, I have R-15 Rock Wool Batt Insulation behind the drywall which i am sure would be touching these heating pipes. Is this going to be a fire hazard?
