Hey all, with the near sight of an extremely cold winter this year i wanted to help my parents out with energy conservation to help keep our gas and electric bill down. I know the basics of building an RSMH, but what i need to know from somebody more knowledgeable on the matter or have gone through it themselves is. How did you convince the insurance to go through with it, and also if anyone could make a list of the possible safety hazards it has it would be MUCH MUCH MUCH APPRECIATED. Thank you in advance.
