Furnace Still Kicks On

So this year we decided to run our wood stove for the first time. I cut some holes in the floor it works great. The thermostat in the house is set to like 64 or 63.It is a split level house and the woodstove is in the basement. So my question is I have the furnace on but the woodstove will get the house to like 67-69 degrees but the furnace will still come on. I have an oil furnace with forced hot water. It's not circulating the water through the pipes to heat the house because its above temperature. So I dont understand why it comes on. I am trying to use to woodstove so my furnace doesnt have to come on.

My thought was the water heater but during the summer I shut the furnace off and the hot water heater still works off electric. So come winter all I did was flick the furnace back on, didnt adjust and valves or anything. So I dont think its kicking on to keep the hot water heater warm.

So I could use some help to figure out why it is coming on. I dont know much about it I have only owned a home for 2.5 years so everything may be normal. It doesnt kick on all the time so its not constantly kicking on but more than i would think when the house is above the thermostat tempterature I set.

Thanks for your help. I can get pictures of my set up if it helps.

my guess its keeping water tank hot...in summer boiler is not on at all...in winter it is so normal to heat water from that source..unless you have it set up to use either electric in summer and winter with isolation switch...ben sr

Thank you very much. Okay if I do have that switch where would I find it?

my guess it would be near the rest of your operation switches for the unit...if not there.. your guess is as good as mineben sr

Just turn off the same switch you had turned off in the summer.
