with 2 euros it heats the house 12 hours

Bills skyrocketing, the past guides purchases. Stoves of the 1500s are back in vogue, heating the house with 2 euros per day. To illustrate the ancient recipe against price increases is the energy saving technician, Enrico Poggiali, as well as founder and president of “Dwelling energy”Rimini association of bio-architecture, founded in 2014, which brings together about thirty experts and university professors.

The Tyrolean stove

It is cleaned once every two years with a vacuum cleaner. And it does not pollute. With 14 kilos of wood a day it heats the house for 12 hours with a daily expense of 2-2.50 euros. But that’s not enough. Used since 1500 in the Alps, the Tyrolean stove avoids maintenance problems and produces very few fine dust, deserving 4 or 5 stars. «I can open the windows while I cook, without losing heat – explains Poggiali -. Radiation heating is in fact a system that uses infrared solar rays ». And to clarify, he takes the example of a cold day in the mountains, when after a brief exposure to the sun he takes off his jacket, feeling immediately hot. An effect of the infrared ray band that does not heat the air, but the bodies, as the president of “Dimora energia” points out.

An ancient history

The operation of radiant heating, already used since the 10th millennium BC. C. in Asia, it was revived in the second century BC in the Bay of Naples by the architect Caio Sergio Orata, inventor of the Roman Baths. A technology also used in the modern age, with storage stoves used since 1500 in the Alps. “A heating system that – he says – can replace modern radiators, because with 7 kilos of wood per load, for a maximum of 2 loads per day, it guarantees ecological and certified heating”. To make the stove, explains Poggiali, “you need from 10 to 20 quintals of material, that is raw pozzolanic earth or refractory tiles rich in alumina, a substance that accumulates heat and releases it gradually”. But he assures us that “you don’t need a lot of space in the house and if the house is on different levels, one on the ground floor will suffice”. The primary feature? It is a passepartout for the crisis. «The heating systems in combination with raw earth keep the heat releasing it slowly. That is to say. By burning at a thousand degrees, the stove accumulates heat but gradually spreads it to 250-400 degrees. Translated: all the energy remains inside the house and even when switched off the system continues to produce heat: it burns fuel for an hour and a half but heats up for 12 », Polazzi highlights.


As fuel, both wood and pellets are fine, but given that a 15-kilo sack of pellets has risen from 3.50 to 15 euros, according to Polazzi it is better to use wood, which has “only” passed from 14 to 20 euros per quintal. A Tyrolean stove instead costs from 7 thousand to 20 thousand euros, but there is the steel variant that weighs much less on the wallet too.
