I just purchased my first house with a old gas-fired gravity furnace (AKA "octopus furnace"). It uses the old Honeywell circular setpoint thermostat. Does anyone know if there would be an advantage to replacing the thermostat with a modern one that can vary the temp at night? Or, does the extended time it takes for the furnace to heat and cool negate any potential savings?

A setback thermostat is a good idea if it is for 4 hours or longer. If the house takes 2 hours to warm up, then setup the furnace temperature 2 hours before you get up.

Sory to say it, your furnace probably only gives you about 40% of usable heat into your house. Out of every dollar, .60 goes up the chimney. Although set-back t-stats are very useful, your furnace itself is not worth the investment.
On average, the furnace probably cycles about 20 to 30 min. before cycling off. By setting the temp back, you would greatly increase the run time and thus increase your fuel bills. I would leave the t-stat at a steady temp.


Hope this info was useful:

Thank you for the reply. The local power company was no help whatsoever! I guess that my efficient days will wait for a new furnace.

Changing the thermostat to a more accurate digital programmable is not a bad idea, your old thermostat is probably a Honeywell t87f a little round gold devise, note most of the old thermostats have mercury in them so please be careful when working around them. And check with your locality on proper disposal.
Setting the heat back can really save you money on utility bills only if the house has enough insulation in the walls, floor and ceiling.
You want to make sure the cracks are caulked and no bad weather striping around doors.
If you do not have proper insulation I recommend to keep the thermostat at one setting and begin looking into additional insulation.
In regards to lighting the pilot, look for the main burner compartment ( follow the gas line) look for printed instructions on how to light it.
Let me know if you need further help.
