Why does my Pyroclassic not get as hot as traditional 'black box' style wood fires?
The Pyro is not a conventional radiant heater. As with all fires it can only generate the heat available from the fuel loaded into it and a single kilogram of wood fuel, soft or hard wood, carries the same calorific value by weight, so if a 'black box' fire is using 3kgs an hour of fuel and yours is using 2 then the other has 50% more heat being generated during the same period.
A percentage of the heat from a 'black box' wood fire will be lost up the flue that would normally be captured in the ceramic cylinder of the Pyro. However, this doesn’t generate more heat, it just recovers some of what might have been lost.
If you want more heat then more fuel and air is the way to generate it. Load an extra piece of fuel in each time and leave the Turboslide open for a little longer, this will build more heat quicker and get the cylinder up to a higher temperature.
The maximum temperature wood fuel can combust at is 1100c and the cylinder wall in your Pyro is capable of withstanding temps over 1500c so don’t worry about getting your fire too hot. The other components like the first section of flue and the coloured panels will show signs of high temp levels long before the cylinder.
