A hopper, an auger and a fan — and three parts that wear
A pellet stove is a wood stove with a machine attached: a hopper, an auger that feeds the burn pot, a fan that supplies air, and an igniter that lights the charge electrically. That machinery is what makes it programmable, and it is also what makes it a different purchase from a log stove. Four figures matter and all four are published. The output range — pellet stoves modulate, so they state a minimum and a maximum, and the minimum is the one that decides whether the stove will be comfortable in a mild October. The hopper capacity in kilograms, read against the hourly consumption in kilograms per hour, gives the only figure that describes living with one: how often it must be refilled. A 15 kg hopper burning 1,2 kg/h at full output is a twelve-hour stove. The noise in decibels, which a log stove does not have at all, and which is the single most common regret in this family. Then the parts that wear and that a listing rarely lists: the igniter, the door and glass gaskets, and the burn pot. A stove whose maker publishes those part numbers is a stove that can be kept running. We compare nominal output, reduced output, efficiency, hopper capacity, noise level, flue gas temperature, flue outlet diameter, stated coverage, energy label, control, dimensions and weight.
5 kW, on wheels, black
A 5 kW pellet appliance on wheels, and the least documented listing in this family: a model code, a colour, and the output in the title.
Best for: A small space where the appliance has to be movable and the data sheet will come from the maker
Water-carrying, majolica clad, A+
A water-carrying pellet appliance in bordeaux majolica whose listing publishes its own title, a product type and a brand — and nothing further.
Best for: A heating circuit where the model is already specified and the figures will come from the maker’s own documentation
11 kW, A+, EN 14785 named, auto cleaning cycle
The only appliance in this family to name its test standard, and the only one whose coverage claim says out loud that it depends on the building.
Best for: A buyer who wants the standard named and the cleaning mechanisms described before committing
460 × 520 × 980 mm, white, no output published
Sold under the Italian word for a range rather than a stove, with external dimensions and nothing else — no output, no efficiency, no connection.
Best for: A buyer working to a tight footprint who will take the figures from the maker rather than the listing
12 kW, Ø 80 mm outlet, heating only, white
Publishes the one figure this shelf is built on and most listings omit: the flue connection, at 80 mm. Heating only, with air circulation.
Best for: A room where the flue is 80 mm and the buyer needs that confirmed before ordering pipe
Fully automatic, Wi-Fi app, ceramic igniter, multiple connection
One dense feature line covering app control, a ceramic igniter and — the notable one — approval for connection to a shared flue.
Best for: An installation where a shared flue is already the situation and the maker’s statement is what is needed
9.9 / 4.3 kW, 91 %, 15 kg tank, 34 dB, Ø 80 mm
The only listing in this family to publish a noise level, a consumption, a hopper capacity, a run time and both ends of the output range.
Best for: A buyer who wants the whole data sheet in the listing and will read the two internal contradictions
18/10 kW total, 12.5 kW water, 90.8 %, 40 kg tank
A water-carrying appliance that publishes both halves of its output, its efficiency, its hopper and its run time — and a subsidy claim with its own disclaimer.
Best for: A heating circuit that needs a stated water-side output and a hopper big enough to be left alone
19.2 kW total, 15.5 kW water, 138 °C flue gas, A++
Three figures, and they are the right three for a water-carrying appliance: total output, water-side output and flue gas temperature.
Best for: A heating circuit that needs the largest water-side output on this shelf and will take the rest from the maker
Only the specifications at least four models out of five state. A column that is more empty than full compares nothing.
