Re: [GBlist] question about turning heat down
This reminds me a little of the perennial question (in certain circles...)
of whether a shower or a bath uses less water. The answer is to experiment
with your own situation -- some people form rigid beliefs that a shower (or
a bath) always uses less water, but in actuality it depends on the size of
the tub, the flow rate of the shower head, the length of the shower, etc.,
and so varies from house to house and individual to individual. If they
wouldn't think it too silly, your students could experiment -- turn off the
heat overnight, and when they turn it on again the next day record how long
the heater runs before reaching the set temperature. Then record it again
the next day, after turning the heat down (not off) and night. Factor in
any difference in nighttime or daytime outdoor temperatures...
