So for my school project we have to design a container that will best insulate heatI decided to use polyester for the inside but what would a good container? The project goes as followsWe place a can with hot water into the container and let it sit, and then see how much heat it lostThe goal is to lose as little heat as possible.I would like to use a material rather than a store bough one (besides we get deducted if we do buy)
Fiber glass or rock wool matting of the sort used to insulate eavesYou could also try a thick blown polystrene tube or a container filled with beads of it.
It really depends on your definition of economic really and of course an aesthetic issue too Based on economy of fuel cost/BTU the solid wood winsA pellet stove will cost 50% more for the same amount of BTU's A pellet stove has the advantage of heating without the maintenance of feeding wood into the fire all day longJust fill the hopper and you are good to go for daysThe downside is a pellet stove needs electricity to feed the pellets so if the power goes out so does the heat My personal recommendation would be the tried and true wood stove with a ceramic glass door (but modern technology for high efficiency rating) Heres why: -You get the visual appeal of a fire -Heat if the power goes out -Cheaper to purchase than a pellet stove -Less costly to operate per BTU I hope that helps
