I've been experimenting with my thermostat the past couple of weeks to

at 67 degrees my boiler will cycle every hour or two to maintain the
temp - but if I set my thermostat to 66 degrees it will cycle every
4-6 hours. It's been around the 32 degrees outside all week. Is there
a natural temperature that a house can hold for longers periods? If
so, how can I raise that temperature?

Well, the first thing I noticed was a possible problem with your
control variables.

1 - I've been experimenting with my thermostat the past couple of
weeks (i.e. weeks - plural)
2 - It's been around the 32 degrees outside all week (i.e. week -
singular)

Unless it was also around 32 degrees during the first week of your
experiment, those results may be invalid. Assuming everything else
remained constant - insulation, windows, number and duration of times
the doors were opened, hours of sunlight, etc

Just want to add wind speed and direction.
