What size stove does your home actually need?
Two questions decide which stove fits your home: how many square meters you are heating, and what the building is like. Everything else — the look, the features, where it sits in the room — comes after.
Get the size wrong in either direction and you pay for it. Too big, and you burn pellets on capacity you never use. Too small, and the stove runs flat out all winter while the far bedrooms stay cold anyway. Here is the ladder, step by step.
Start with your square meters
40–100 m² — the 8KW pellet stove. The right fit for most apartments and smaller homes. One load of pellets runs 10–14 hours, so a morning fill carries you through the evening. See the 8KW pellet stove for the full picture.
100–150 m² — the 15KW chimney stove. The same 10–14 hours per load, with the extra capacity an open-plan living area or a larger floor actually needs.
When one warm room isn’t enough
150–250 m² — the 30KW hydro stove with boiler. At this size, warming the air in one room doesn’t reach far enough. The hydro unit heats water and pushes it through radiators, so the rooms at the end of the corridor warm up too. One load runs 12–18 hours.
300–375 m² — the 45KW autocleaning boiler. For large houses, working with a pump to move hot water through the whole system. It burns 1–2 kg of pellets per hour, runs 16–26 hours on a load, and the autocleaning system cuts down the daily ash routine.
All of these run at 95% efficiency, and that is where the real argument lives: switching to pellets saves up to 70% of winter fuel costs.
If the kitchen is the heart of the house
Two models heat and cook at the same time, and both are sized for 80–130 m². The 10KW stove with cooktop burns 0.8–1.5 kg of pellets per hour and gives you a hot surface on top. The 12KW cooker burns 0.8–1.8 kg per hour and is built around the cooking.
If your family lives in the kitchen from November to March, either one puts the heat exactly where you spend your time.
Ceilings and insulation change the math
The ranges above assume normal ceiling height and reasonable insulation. Real houses are messier than that, so adjust:
- High ceilings. Old stone houses and arched salons hold a lot of air. You are heating volume, not floor area — count your home at the top of its range, or step up one size.
- Weak insulation. Single glazing, an uninsulated roof, walls exposed to mountain wind: same advice. Aim high in the range.
- A newer, well-insulated apartment. The bottom of the range is realistic. Don’t let anyone upsell you past it.
- Between two ranges? If your home falls in a gap — say 270 m² — don’t guess. Ask, and we will look at the layout with you.
Don’t forget the power cuts
One practical note: pellet stoves need electricity for the igniter, the feed and the fan. With Lebanon’s power cuts, plan the stove onto your UPS or generator line before winter — the draw is modest, and you can message us to size the backup for your model.
Measure before you decide
Walk the house once with the floor plan in mind: which rooms do you actually live in through winter, and how many square meters do they add up to? Then put that number into the fit finder — it asks a few questions and points you to the size that matches, and partner installation takes it from there once you choose.
