What the maker’s page says
A bronze steel water-carrying pellet appliance carrying an A++ energy label, at
19.2 kW nominal output with 15.5 kW on the water side and a flue gas temperature
of 138 °C. The title states that the maker’s R-FX kit is included.
Three feature lines in total. No efficiency, no hopper capacity, no run time, no
flue outlet diameter, no electrical consumption and no noise level.
Three lines, and the right three
Total output, water-side output, flue gas temperature.
For a water-carrying appliance that is close to the minimum useful set: the
split between the room and the circuit is what a heating system is designed
around, and the gas temperature is one of the appliance inputs a flue
calculation consumes.
It is a short listing that is short in the right places, which is not the same
as a short listing that is short everywhere.
The coolest flue gas on this site
138 °C.
Against 227, 250, 312 and 325.6 °C on the log appliances this site covers, that
is a different order of figure — which is what a condensing-adjacent,
heavily-exchanged water appliance is designed to produce.
It is not a score. Cooler gases mean more heat stayed in the system rather than
going up the chimney, and they also mean the flue is working under conditions
that the sizing calculation has to account for. That is a calculation, and this
page points at it rather than making it.
The largest output in this family, and why that is not the usual warning
19.2 kW would be a warning on a room-heating appliance: oversizing is the
damaging direction, because an oversized appliance gets run throttled.
A water-carrying appliance is different. Most of its output goes into a circuit
rather than into the room it stands in, and it is specified against a heating
demand rather than against a floor plan.
Which is why this page reports the split rather than the total, and why
comparing this appliance to an air-only 11 kW stove on a single kilowatt figure
compares two different objects.
What three lines cannot tell you
The efficiency — absent, despite an A++ label that is derived from one.
The hopper and the run time, which on an appliance sized for a whole house are
the difference between daily attention and weekly.
And what it connects to: no outlet diameter.
Where it is sold
The German market only, with an offer found there at the time of the survey.
