radiant heating is especially important in a tall or big room with a large amount of open airspace overhead. That high ceiling looks beautiful, but heating all that air can waste a lot of energy that could be used more efficiently. By heating the lower half of the room more, and the top half less, the heat is put where you want it; and radiant heat disperses much better and therefore rises more slowly
The shock freezer, or blast chiller, (from Coldline) uses a much wider range of temperatures with high precision. A traditional freezer takes up to 12 hours to freeze food, but a shock freezer takes less than half an hour! “Because the air inside the appliance can go down to [minus 40 degrees], it cools to zero quickly. It chills fresh foods [to 40 degrees] in a few minutes. The deep-frozen food can then be stored in a normal freezer, but it gains 70 percent of additional shelf life, maintaining a high quality.” It uses R290 gas, a refrigerant-grade propane with low environmental impact. The gas is non-toxic, with zero ODP (ozone depletion potential) and a very low global warming potential (GWP), of 3.8. (A traditional refrigerator typically has a GWP of about 10.)
Groundfridge (from the Netherlands) - Portable and waterproof, the organically shaped cellar doesn’t require any building permits, just thorough knowledge about the ground where it’s to be installed.
