Question about oil heat?

You'll also have to shut the door to that room.

The key here is to manage the heat you are using, ie, what temp you are asking the heater to heat the house up to. They say dropping your heated temp a degree or 2 can save some cash.

I just installed a digital thermostat - it was pretty simple. I set it to low, 62ish when I'm gone and 68ish when I'm back. I've found with steam that its best to ask for a lower temp than what you want since the steam keeps coming for a bit after the heater shuts off. I find that set at 67-68 it tops off at 71.

hope that helps.

Shutting off one room would probably save somewhat in that the rooms still being heated would get a fraction more of the steam not heating the room you turn off, hence they would heat more quickly and lessen the time the boiler is running.

I can't say exactly how much the savings would be not knowing how big the rooms are in comparison to each other, etc etc.

How about this to compare to. They sound the same to me just different heat omitting substance being created. We know people who have wood burning stoves that have pumps which circulate the water in the stove. Outside wood burners. If you hook one radiator to the wood stove it will take so many logs to burn per year to heat your home. If you add a radiator the water will have to circulate farther thus bringing the temperature on the wood stove down faster, thus opening the flap to allow more air to burn the wood faster to keep up with circulation to heat the water. Sounds like the same concept to me. For each additional radiator you add to the system, you will burn more wood. With only one radiator you burn considerably less. All because of the distance the water travels before it returns to the stove and drops the temp. I would imagine that it would save money if you shut one off. It would be that much less to circulate. Unless I'm way off on how your system works, because I am not familiar with them, I would say yes you would see a difference in oil consumption.
