Green building advisorGreen building advisor - A typical two-stage condensing gas furnace has a turn-down ratio of less than 2:1. With most of these furnaces, the low-fire output is still 60% or more of the high-fire output. When a furnace with a low-fire rating of 60% is oversized by a factor of 1.7, you could cover 99% of the building’s heating needs at low fire.

2. vinyl siding comes down to about 8-12” from the top of finished grade. 3. the sill looks to be in decent shape but it not airtight on the foundation. 4. the exterior foundation face is a mix of rubble stone, faced with some stucco. Lots of stucco has broken and crumbling, as is some of the rubble. 5.1. Independent ducting. The best way to duct a dehumidifier is to give it its own independent ducts. The intake side is connected to a grille (or maybe multiple grilles). The supply side is connected to a grille or register (or maybe more than one). It’s the simplest way to set up a whole-house dehumidifier.The first time I detailed a “ slabless slab ” was in 2013.
