Our project is a waterfront in central NJ. The house is block with a crawl space and has approx. 1100 sq.ft. of living space. We have gutted down to the studs.We are putting a new high eff. natural gas furnace/AC.& tankless hot water system. Also installing all new windows. There is no insulation. Would like to have a second source of heat as I have been told that the new equippment can not be hand lit in the event of power outages. I am as old as the house and trying to learn as much as possible. Any ideas would be greatly appreciated.
