10-25-'24, WBR Live, ''Daily Constitution'', ''Hullbilly Friday'', (pics on wimkin), Still have a few things to button up in my heat recovery experiment, but the ''big rocks'' are in the jar, and just waiting on the smaller parts to fill in the details. I will post the bill difference a few times this winter to show the effectiveness vs the investment. Depending on the price, requirements, and availability, I will replace the greenhouse plastic with glass, as the size and shapes become available. The savings and complications of the greenhouse (in particular) are from the required construction (UBC?) definition of a ''appliance'', in that it is NOT attached to the primary structure. It is a ''stand alone complex'' that only touches the building, and does not require said building to support it. The second potential money and style conservation is that the heat from the fire pit will warp and affect the cover plastic long before any (tempered/difficult to cut/shape) glass that may replace it. If that don't happen over a ordinary winter, then tempered glass should not be required for the heat sensitive areas (or some sort of plastic product may be substituted as well) to be approved in -a lot- of districts. The large opening may be reduced for a shower door entrance, or fixed, depending on the complications, and the odd shaped sections will be plain glass stock, adjusted to size with extra scrap aluminum ''L'' angle extrusions to fit pre cut glass to the existing frame. The north side heat transfer duct will still need a down duct to move the air from the collector without a motor by locating the exit close to the cold air exhaust from the heat pump. FYI, 1 hour after sunrise, the black coated door is 70F, and the deck is 45F, (40F outside/ambient temp). I will post the spec results as the winter proceeds.
