One warm room or the whole house? Stove vs hydro

Every winter the same conversation happens in living rooms from the coast to the mountains: do we heat the room we sit in, or do we heat the whole house? It sounds like a money question. It is really a question about how you live.

A pellet stove heats the space around it. A hydro system heats water and pushes it through radiators in every room. Both burn the same pellets, both run at 95% efficiency, and either one saves up to 70% of winter fuel costs. The difference is where the heat goes — and that is what should drive your decision, not the brochure.

Stoves heat where you live

If your family spends the evening in one or two connected spaces — a salon that opens onto the dining area, say — a stove is the honest answer. The 8KW stove covers 40–100 m² and runs 10–14 hours on a single load of pellets. The 15KW chimney stove stretches that to 100–150 m², same 10–14 hours per load, useful when the living area is large or the ceilings are high.

A stove gives you real warmth where you actually sit — not “takes the edge off” warmth. The trade-off is just as real: walk down the corridor to a bedroom and you will feel the temperature drop. A stove does not pretend to be central heating, and for a lot of apartments that is exactly fine. The bedrooms get duvets; the living space gets the fire.

Hydro heats the rooms you’re not in

A hydro system works differently. The unit burns pellets to heat water, and a pump circulates that water through radiators around the house. The fire stays in one place — a side room, a kitchen corner, a covered balcony — while the warmth shows up in every room with a radiator, including the bathroom at six in the morning.

The 30KW hydro stove with boiler covers 150–250 m² and runs 12–18 hours per load. For larger homes — village houses, two floors, up to 300–375 m² with a pump — the 45KW autocleaning boiler runs 16–26 hours on a load and burns 1–2 kg of pellets per hour. The autocleaning part is not a gimmick: in the deep of the season, it means less daily handling.

Hydro makes sense when the household spreads out — kids studying in their rooms, someone working from home during the day, grandparents who feel the cold at night. It also makes sense in mountain homes, where corridors and bathrooms turn properly cold, not just cool.

Draw your house before you decide

Here is a simple exercise. Sketch your floor plan and mark where people actually are between five in the evening and eleven at night. If the marks cluster in one zone, a stove sized to that zone does the job. If they scatter across the plan, radiators are what you are really shopping for — whatever you thought you came in to buy.

The fit finder on our home page runs the same logic with your square meters, so you can check your answer in a minute.

One more thing: the power cuts

Pellet stoves and boilers need electricity — for ignition, the fan, and the pump on a hydro system. Plan for that before winter, the same way you plan for the fridge. If you want heat that ignores the power situation completely, the wood stove with oven is the no-electricity option: 10KW, 60–100 m², fully manual.

Whichever way you go, installation is handled by our partners, spare parts are available locally, and after-sales support is there 24/7. On supported models, Wi-Fi app control lets you start the heat from the car on the way up the mountain. The choice between one warm room and a whole warm house is yours — just make it from your floor plan, not from the showroom floor.
