The table below shows a selection of wood types with the corresponding energy
content depending on the water content:
Wood type
Spruce
Pine
Beech
Oak
The table below shows the relationship between fill level and weight. It compares
beech (example of hardwood) and spruce (example of soft wood) with a water content
of approx. 20%. Using our example above with beech, the fill level of an S1 Turbo 15
would, therefore, be approximately two-thirds.

Feed based on output:
Only replenish the fuel if energy is needed!
❒ If too much fuel is loaded, the boiler drops below its minimum output limit and
goes over to "constant burn" operating status (blower fan switches off)
➥ The level of efficiency drops in constant burn mode, the emissions
increase and the boiler can tar up (pitch formation!)
