Pellet heating: cheap until everyone wants it

Pellets: the cheap heating that antiestéticars its own popularity

A €3.50 bag of pellets heats a 150-square-metre home all day, according to one forum post. At €4.20, with two stoves running, each burns through nearly a bag a day, says another. The difference between those two scenarios is not the climate or the insulation: it is the year you bought. Whoever raised the question — a home in a coastal area, under 200 metres, no natural gas, with hot water covered by a solar panel and an electric backup heater — got a unanimous answer: the system works, it is cheaper than heating oil, and nobody knows how long it will last.

How much it costs to heat a home with pellets

The figures in the conversation paint an uncomfortable picture. An energy-equivalence calculation from one user puts firewood at 10 cents per kilo and pellets at 20 cents when buying a thousand kilos: the equivalent of a litre of heating oil comes to about 44 cents, roughly half the price. Another account points to daily spending of three euros in a very cold area, far below what natural gas costs, whose tariffs would have risen between 50% and 75% in a year and a half, reaching €800 over three winter months, according to one story.

The problem is that those prices are no longer to be found. Pellets have tripled in price in four years, according to one account, and a good-quality bag runs between €4.20 and €4.50 with home delivery. Only those buying in bulk or with a privileged supplier get €3.50. The conclusion that keeps coming up: they were a good alternative when a bag cost two euros.

Stove, boiler or fireplace: which setup makes sense

The choice of equipment determines cost and maintenance. A pellet boiler requires about seven square metres of space, a vacuum-fed delivery system and, above all, a local distributor: there have been supply shortages. A stove is simpler and programmable — coming home to a warm living room is its big advantage — but it demands daily cleaning and hauling bags. A traditional fireplace wastes up to 90% of the heat unless the firewood is free.

There is a middle path several users mention: boilers that burn pellets and firewood alternately, or steel and refractory inserts that fit into an existing fireplace. For those with an oil boiler, switching means a new installation and building work. Grants based on ecological criteria exist in some regions, but they do not cover the initial outlay.

The risk nobody rules out: pellets becoming a bubble

The most repeated warning is not technical, it is speculative. If the system goes mainstream, bags could double in price and the advantage would disappear. Pellet manufacturing is subsidised; when the aid is withdrawn, costs will rise. Firewood and wood chips — cheaper because they require no pressing — remain a fallback for those with access to woodland or agricultural prunings.

Against that, the electric alternative is gaining ground in the discussion: heat pumps and water heaters with an integrated heat pump, using the old boiler's flue outlet for the new installation. The argument is simple: less maintenance, less noise, fewer bags. The counterargument too: electricity bills have not stopped rising.

In the end, the decision depends on something that appears in no performance table: how long you plan to live in that house and how much space you have to stack bags. At current prices, pellet heating still works out cheaper than heating oil. At prices from four years ago, it was no contest. Which of the two scenarios will define the next ten winters?
