Shutting off water to an oil furnace


I have an oil furnace that supplies hot water for both the tap water and baseboard heater. It is plumbed with copper pipe. A few nights ago, one of the sweated joints failed and developed a slow drip. Not much, but enough to wet a lot of the basement floor over a few days.
I'm wondering if when I go away for an extended period, if I can shut off the main water supply valve to the house (from a well) just to be on the safe side.
Any harm in this?
Thanks.

is it dripping at the domestic hot water line out or the common feed of cold water to the boiler...till it can be resoldered wrap it 5X around with electrical tape "NEAT" and a radiator clamp wrapped around that will quick fix it till repaired.

Thanks for the reply. I guess I should have been a little clearer. I replaced the bad joint and a few more with new copper fittings and pipe and all is fine. I'm just concerned a new leak may develope at a different location at some point while I'm away for 2-3 weeks. If the water was shut off, it would limit the flow. Just not sure if it affects the heater/boiler.

if it was to leak it would happen ASAP right after you resoldered if it's tight now it will never leak,the soldered joints are stronger then the pipe itself.a HW baseboard setup should be tight with no leaks so i would let it ride and go on trips,the well pump pressure can't cause leaks...but shutting off the water to solve a doubt with a pipe leaking creates a situation of cycling a boiler to maintain a setback temp(55F)while out on a trip a more critical setup..i would let the water stay open unless there is an eathquake or somebody steps up on it it isn't going anyplace

Ayuh,....

If the Boiler can't refill,...
The whole Heating system will either Shut-Down, or Burn Up.....
