Is there a Scientist in the audience? A physicist, if that's not asking too much? Retired even…? ;~)
So, I'm looking for cost-effective + creative ways to heat just a small "space around my face" (& body).
My search & some of the info it's brought, so far:
a. Thinking-up designs for an indoor "box inside a box" (= room), that'd enable me to cut Electricity co$ts, both by cutting the volume+contents to be heated &/or by placing a transparent / translucent box (that may have been sold as a plant-growing / glasshouse) outside, to reduce effects of breezes+winds & rely on sunlight to heat its inside space (in Winter). If the house is cool, & the collected heat hot, maybe look for ways to transfer heat inside
b. Starting with Reverse Cycle units, split systems require co$tly installation. (Are they Really the most
cost-effective heat sources ('pumps) out there? I suspect running costs will be higher than current system,
as they heat the Air, not the things in a room, as Infrared panels & globes are said to do. New to me.
c. Portable R/C units are reportedly much more co$tly to run, especially if they have a single exhaust-hose… & are also [said to be] noisier, in early models of a series.
d. Infrared Panel(s) or Globe(s): The claim is, that they're more cost-effective, since: "They heat things (eg, wall behind the panel) in the space/room, Not the air" (True of False?)
e. Any1 got a "HotPod Electric Heat Pack"…? How many Watts does it draw, & for how long does it:
Need to "Charge" & Stay Hot on a "Charge"? Oh, & what technology does it use?
It's said to be a replacement for Hot Water Bottle (which Chemist Warehouse offers for ~$6.50)
HotPod's are ~$31.49 (@ both Amazon & CW), but it's unclear if they're worth so much.
Help us clear that up, if you know, thanks?
etc.
(What source(s) of Higher-Efficiency Space Heating are we missing?)
Hot water bottle on your face does it.
