Why do you need a second electric meter to excrement with? You can
read your own meter every day at the same time. As long as you record
when you are drying clothes or other significant electricity burning
events you should be able to test for no hardware costs.

Are you torturing the group by not doing your own meter reading and
reporting back?

Hi Jim,

I am lost...

How would reading my meter at the same time every day tell
me my heat-related energy consumption?

Thanks,
Day zero meter reads 1480
Day one with no thermostat changes reads 1520
Day two no thermostat change 1570
day 3 no thermostat change 1620
Day 4 after thermostat rollback 1680
day 5 with thermostat rollback 1740
day6 with thermostat rollback 1800
day 7 no thermostat change 1850
day 8 thermostat rollback 1910
day 9 thermostat rollback 1970
day 10 no thermostat change 2020

and so on. Just read the meter every day at the same time. Do the
math. Do it over enough days to factor out clothes dryers and baking
festivals. If there is indeed any significant energy saving to be had
by thermostat rollback it will show up with a month of measuring.
Especially if you do rollback every other night.

That said I think when I feel rich I will buy

You are not measuring how much you spend on heating, you are measuring
much less or more you are spending by trying different thermostat
strategies. You also need to note wind, sunshine and outside temp. My
heat does not run on a 50 degree day with sun and little to no wind.
