I have an oil burning furnace for heat and hot water. The problem is the heat doesn't come on unless I turn furnace up to 71 degrees. Is there a way to adjust my thermostat so I can leave it at 65?

It is difficult to determine why the furnace will not
come on if the thermostat is set for less than 71

Perhaps I can help a little with the following thoughts:

1. Do you have a fireplace? If so, is it burning in the
same room as as the thermostat? If so, the thermostat is
sensing that the room is warm enough and will not come on
when the room is warm.

2. Is the sun shining on the thermosta?. Again, if the
thermostat senses that the room is warm it will not come

3. Do you live in climate that is keeping the house from
getting colder than 71 degrees? If so the thermostat is
sensing that it does not have to come on.

4. Have you noticed a common thread of thought here? If
the room is warmer than 70 degrees from any cause, the
thermostat will not allow the furnace to come on.

5. One solution would be to turn the thermostat up and the
furnace will come on but the house may become warmer than
your like.

6. If all that does not resolve the problem, Invite a
heating specialist to come to your home and investigate
the problem.
