I suppose you could have a time clock installed on the boiler, to shut the
entire system down during predetermined hours of the day or night. The
problem with this approach, is that once the system is cold, it will have to
run for a longer period each time it is fired, which may use the same amount
of fuel as it does now. You could try turning down the boiler's high limit
aquastat to 125 degrees for the summer, and see if that helps

Is there a way I can get my water heater from tripping my oil furnace
to go on all night to keep the reserve tank hot? It's using up about
1.4 gallons a day this summer and all we use the hot water for is
taking showers -about 1 per day, and washing dishes - every 3 days. I
think it's using too much oil just to keep the water hot and I'd like
to be able to have it turn off from 11pm to 6am every day so I don't
waste so much oil while I sleep.

If I cannot do this myself who do I call to get it fixed. Will any
furnace specialist be able to fix it or do I need to contact someone
with experience with tankless systems?

Just for clarification my tankless system is not the square box on the
wall, it's a mini tank connected to the furnace about the size of tank
used to power your standard outdoor gas grill.
