Not every home has a large living room with space for a bulky stove. In apartments, lofts or homes with narrow hallways, what you need is a small pellet stove: enough heating capacity without excess, a shallow design and quiet operation.
In this guide, we explain how much heating capacity you really need, which dimensions and features to look for, which compact models Ecoforest offers and what requirements you must meet to install one in an apartment.
Quick answers
| Question | Short answer |
|---|---|
| What counts as a small pellet stove? | A stove of around 5 to 9,5 kW, designed for one room or a small apartment, often with a shallow design. |
| How many m² can it heat? | That depends mainly on insulation. As a guide, a 6 kW stove can heat a space of around 60–75 m² in a moderately insulated home. |
| Ecoforest compact models | Miami (5,5 kW), Creta (6 kW), Lyon, Monaco and Moon II (7,5 kW), Keops and Vigo III (9,5 kW). |
| Consumption | From 0,5 to 2,1 kg of pellets per hour, depending on the model and power setting. |
| Can you install one in an apartment? | Yes, if the flue outlet meets regulations and the building’s owners’ association permits it. |
How much heating capacity do you need?
The most common mistake with small stoves is thinking that “more power is safer”. An oversized stove in a small room always runs at its lowest setting, gets dirty sooner and can make the room too hot. What matters is matching its heating capacity to the area and insulation:
| Home insulation | Estimated requirement | Area for 5,5 kW | Area for 7,5 kW |
|---|---|---|---|
| Good (new or renovated home) | 60–80 W/m² | 70–90 m² | 95–125 m² |
| Moderate | 80–100 W/m² | 55–70 m² | 75–95 m² |
| Poor (older, unrenovated home) | 100–120 W/m² | 45–55 m² | 60–75 m² |
These are reference figures for an initial estimate, not a precise calculation. In cold areas, rooms with high ceilings or spaces with extensive glazing, use the higher requirement. You’ll find a more detailed explanation in our guide to choosing a pellet stove size based on floor area.
What to look for in a small pellet stove
- Depth and shape: in hallways and narrow rooms, the stove’s depth matters more than its width. Hallway stoves are designed to be especially shallow.
- Flexible flue outlet: the option to vent flue gases through the top, rear or side makes it easier to fit the stove close to a wall.
- Sealed combustion: a room-sealed stove draws combustion air from outside through a duct instead of using air from the room. It is the recommended option for well-insulated, airtight homes.
- Runtime: small stoves have small hoppers. Check how many hours they run on one load at the power setting you expect to use.
- Noise: in an apartment or near a bedroom, quiet mode makes a difference. Find out more in do pellet stoves make noise?
- Controls: scheduling by room temperature, power modulation and control from your phone.
Ecoforest’s compact pellet stoves
| Model | Heating capacity | Efficiency | Hopper | Runtime | Consumption |
|---|---|---|---|---|---|
| Miami | 5,5 kW | 91,2 % | 7 kg | 11–6 h | 0,7–1,2 kg/h |
| Creta | 6 kW | 91,2 % | 11 kg | 17–8 h | 0,7–1,4 kg/h |
| Lyon | 7,5 kW | 93 % | 12 kg | 19–7 h | 0,6–1,6 kg/h |
| Monaco | 7,5 kW | 94,4 % | 11 kg | 17–7 h | 0,7–1,6 kg/h |
| Moon II | 7,5 kW | 94 % | 15 kg | 28–7 h | 0,5–1,7 kg/h |
| Keops | 9,5 kW | 91,8 % | 16 kg | 24–7 h | 0,7–2,1 kg/h |
| Vigo III | 9,5 kW | 91,8 % | 16 kg | 24–7 h | 0,7–2,1 kg/h |
Figures are from Ecoforest’s product specifications. All these models are room-sealed and include ecoSILENCE mode, WiFi and Internet control, and regulation by power setting or room temperature.
For hallways and very narrow spaces: Miami and Monaco
Ecoforest identifies Miami and Monaco as its narrowest pellet stoves, designed for hallways. Miami can vent flue gases through the top or rear, while Monaco offers top, rear or right-side outlets. You’ll find more details in our article on pellet stoves for hallways.
For highly insulated homes: Lyon
Lyon is identified in its product specifications as a room-sealed stove for Passive House homes, with 93 % efficiency and a heating capacity of 7,5 kW: a good choice for new or renovated homes with high levels of airtightness.
Longer runtime in a small space: Moon II
With the same heating capacity as Lyon and Monaco, Moon II has a 15 kg hopper and a runtime of up to 28 hours at its lowest power setting.
If you need a little more heating capacity: Keops and Vigo III
At 9,5 kW, they are the next step up for larger living rooms or apartments with poorer insulation, while still being compact stoves.
How much does a small stove consume?
According to the models in the table, a 5,5 to 7,5 kW stove consumes between 0,5 and 1,7 kg of pellets per hour. With a 15 kg bag costing €5,67 (the average price in AVEBIOM’s index for the second quarter of 2026), each kilogram costs around €0,38.
| Daily use | Estimated average consumption | Approximate monthly cost (30 days) |
|---|---|---|
| 5 hours at 1 kg/h | 5 kg per day | ≈ €57 |
| 8 hours at 1 kg/h | 8 kg per day | ≈ €91 |
Actual consumption depends on the stove’s power setting, the insulation and the temperature you set. We explain it in detail in our guide to actual pellet stove consumption per hour.
Installing a small pellet stove in an apartment
- Flue outlet: it must comply with applicable regulations and local ordinances. In many buildings, venting through the façade is not permitted, so the flue must be routed to the roof.
- Owners’ association: if the flue outlet affects shared parts of the building or the façade, you will need its approval.
- Air intake: in room-sealed stoves, combustion air is drawn from outside through a duct.
- Professional installer: a professional must install the stove in accordance with the manufacturer’s manual.
You’ll find all the requirements in our guide to pellet stoves in apartments, and the costs in the cost of installing a pellet stove.
What if you want to heat several rooms?
A small stove heats the room it is in effectively and, to some extent, adjacent rooms. If you want to distribute heat to other rooms, consider ducted pellet stoves. And if you want to heat the whole house through radiators, a pellet boiler is the right option.
Frequently asked questions
Is it safe to sleep with the stove on?
Modern pellet stoves have multiple safety systems, but they must be installed and maintained correctly. We explain this in is it safe to sleep with a pellet stove on?
Does a small stove use less fuel?
It uses less fuel per hour, but what matters is choosing the right heating capacity. A stove that is too small for the room will always run at maximum power and still fail to reach your desired temperature.
Can I use other fuels?
Some models can use multiple fuels: according to their product specifications, Creta, Lyon, Moon II and Vigo III can burn pellets, almond shells and olive pits, while Keops can burn pellets and olive pits.
Conclusion
For an apartment or a small room, the ideal choice is a 5,5 to 7,5 kW stove that is room-sealed and quiet, with a flue outlet suited to your home. If you need a little more heating capacity, Keops and Vigo III reach 9,5 kW without sacrificing compactness. Explore all of Ecoforest’s air-heating pellet stoves.
