Is it energy saving to turn the thermostat down, when leaving the
house? I mean, the furnace has to run to catch up when I get home. I
have a way of looking at the matter. I'll explain my point of view
after the argument is underway.


Six of one, half dozen of the other. Depends on how long you are gone.
Leaving the thermostat at a steady temperature saves energy. On the
other hand, a lower difference between the inside wall and the outside
wall means lower heat loss. So lowering the thermostat does save energy
in the long run. Now, constantly raising and lowering the temperature
for short periods wastes energy. When you raise it you have to reheat
not only the heating system but the entire inside wall, floor and
ceiling not to mention all the furniture and appliances. When you lower
the thermostat, all those items lose all their heat again the heat is
drawn out into the room and the room loses it through the walls to the
outside. So....use your little noggin.
Wow,
Where are you coming from? The lower the setting the longer the
setting. You save energy. I am talking about how much saving. Just
it saves. Our 'stat is set to 17C from midnight. Back up to 20C at 7 in
the morning. It does make a difference. Now our NG price is 3.80 per
GigaJoule. Electricity is 7 cents/KWh
