Well if it's really just a shorted theromstat wiret, does he need
professional help? Is the OP known to not be good at repairs.
Winter's almost over in much of the world. He has the whole summer to
fix it.

Yes, because the burner is controlled by an aquastat. If he does not know
that or how to get to it and test it, a pro is needed. In most setups, the
thermostat turns the circulator on when it wants heat.

In this case it can be a bad relay, sensor, aquastat.
