Cold at Home: 12.5 Euro Butane or 60% Humidity

A scene repeats every winter across much of Spain: entering an empty apartment with temperatures at six degrees and 95% humidity, only to find that conventional heating fails to raise the heat in under two hours. Those who have experienced this know the problem is not just the cold, but the humidity, energy prices, and the reality that butane is no longer what it used to be. The cold season begins with the same recurring question, but with an increasingly uncomfortable answer: how much does it really cost to stay warm without going broke?

Butane, Paraffin, or Pellets: The Calculator Rules

The butane cylinder is around **12.5 euros**, according to figures from those who crunch the numbers. A butane stove on minimum consumes about **100 grams per hour**, yielding **125 hours** theoretically, or roughly **20 days at five hours daily**. In other words, heating a room is cheaper than a boiler with radiators, provided fixed charges do not weigh too heavily on the bill. The problem is that butane heats a room, not a house, and performs worse in humid areas.

Paraffin is a different story. Its calorific power is huge, it heats quickly, and there are second-hand stove deals almost given away, but the fuel is expensive and is consumed at a rate of a full canister. A 25-liter canister may last ten years if used only to give a quick warm-up upon arriving at a holiday home. For continuous use, the calculation skyrockets: some claim paraffin costs twice as much as butane. And all indoor combustion shares an ignorable problem: **carbon dioxide and water**, along with odors.

Pellets have emerged as a third option. A 9.5 kW stove installed in a 100-square-meter living room consumes one bag every two days, running for twelve hours, with a cost of **2 to 2.50 euros daily**. The initial investment, including installation, rarely drops below **1,500 euros**, deterring renters or those living in family homes. Firewood remains cheaper, especially if gathered from the woods, but pellets win on convenience: clean, constant temperature, and no need to tend the fire.

Humidity, the Overlooked Factor

Here comes the unexpected twist. Several testimonies suggest that relative humidity alters thermal sensation more than the thermometer suggests. A striking case: an apartment in Madrid maintaining **23 degrees** indoors while it is 2 degrees outside, without turning on heating more than sporadically, after raising indoor humidity to **60%**. When humidity drops to 50%, the feeling of cold increases. It seems counterintuitive, but those who live it defend it.

At the opposite extreme, some claim that with humidity levels of **60-70%** and 14 degrees in the room, the cold is unbearable. The repeated conclusion: in humid coastal areas, such as Valencia or Murcia, eight degrees feel worse than two dry degrees in Krakow. The dehumidifier has become a cult appliance, capable of transforming a cave into a livable home without touching the thermostat.

Clothing as a Heating System

While others debate fuels, some have opted for the cheapest route: dressing warmly. Socks with at least **10% wool**, thermal shirts, fleece linings, robes, and blankets. The difference between a polyester sock and one with wool, according to testers, is abysmal: synthetic materials sweat and smell, while wool breathes and warms. Aluminum and activated carbon thermal insoles, for less than three euros, allow wearing light shoes even in mid-January.

For sleeping, the classic arsenal: duvet, two blankets, hot water bottle, and polar fabric sheets. The electric sofa blanket has consolidated as a low-consumption solution—about **50W**—and contained cost. The electric bed warmer serves the same function in bed: low power, high comfort.

The Disorienting Data

The conversation shifts to an unexpected issue: comfort temperature has become a class marker. Some live at 23 degrees without turning anything on because their building’s communal heating pipes pass through their apartment. Some wake up at 14 degrees and consider it normal. And some set heating to 25 in winter and air conditioning to 20 in summer, with chronic colds as the bill. The question is no longer how much it costs to stay warm, but how much we are willing to pay to not feel cold.
