The reading the tech is taking using a probe in the stack is simply a combustion efficiency number that is based upon gas readings in the stack after it has left the boiler. This only is a measurement of how well the burner is turning fuel into heat energy, it has nothing to do with how efficiently the boiler is collecting that heat energy and transferring it to the water in your boiler/ heating system. The trick to saving money is to transfer as much of the heat energy into energy that is actually used to heat your premises. This is where the science, magic, Voodoo and unfortunately creative marketing come into play.
