We have oil heat (forced hot water). Lately, we can hear the water running through the pipes at 7-10 minute intervals throughout the day and night. We have not experienced this in the 7+ years we have lived in this 12 ear-old colonial. What is causing this to happen?

Do you have cast iron radiators? When was the last time you vented the air out of each radiator/register?

Thanks for your response. No, we don't have radiators; we have baseboards. This may be a stupid question, but could venting the air still apply?

Yes, try venting the baseboard radiators.

I agree with arkayassoc, try bleeding air from your baseboards. Hopefully on your baseboards there is a place
to bleed the air out. If not, maybe the installer put in
purge valves at the boiler. You will hear the "waterfall"
like sound until all the air is removed. Good Luck!

Also, in some hydronic(Martian for hot-water based heat)systems, a circulator may have been included or retrofitted into the system. This simply circulates the water through the house, which helps reach the higher floors and minimizes the need for bleeding.
In such a case, the circulator may also circulate pockets of air trapped in the system, causing your running water sounds.
Check for one, and then bleed the base boards as suggested above. You won't have to bleed hopefully more than once a year.
