Here is the problem:
2 Story house. Separate Apartments , with each having their own utilities. Lower Apartment, has Gas Boiler heat system. That works great.
The Upper Apartment, on the other hand, has a forced hot air Gas fired Furnace in a furnace room that is just off the Master Bedroom up there. In fact, if you were in the master Bedroom, and looked at the door that leads to the Furnace, you would have thought it was just a Closet. Now, the Ductwork for the Gas Furnace is ALL in the Attic. Heat vents are all on the upper parts of the walls near the ceilings. Got to find some way to eliminate that heating system, so that it does not heat up the flat roof , and cause Ice and water damage. The ductwork is just a few inches from the flat roof edge in the Attic. No amount of insulation or wrapping can prevent the attic from heating up , causing the Ice and Snow problems.
What are my options?
I was thinking of just shutting that furnace off, and installing a direct vent , through the wall Gas Furnace in the Living Room upstairs. That would heat the Living Rm , Dining Room , Kitchen and possibly the Hallway leading to the 2 Bedrooms and the Bathroom. That still leaves the question on how to heat the 2 Bedrooms and the Bathroom.
How would I run the Gas lines for those heaters? Through the walls? As it is now, the Gas line for the Furnace runs up from the Basement , inside the walls and then comes out of the wall in the Furnace room.
