Masonry stoves are an environmentally friendly, comfortable and safe heating system, widely used in the past, but to be adopted in the future, to pollute less and enjoy excellent comfort in your home.

Heating your house with wood is part of the secular culture and reminds us of the typical houses of our cities. However, times have changed and the legislation is more and more restrictive. Indeed, for several years, wood has been considered one of the most polluting fuels, especially when it comes to the production of fine dust.

But today there are stoves that burn wood very efficiently and can emit up to thirty times less particles than regular metal stoves or fireplaces.

Among these stoves, there are masonry ones built in situ, which, not by chance, were not affected by the bans.

Homogeneous heat.

The quality of the heat is very important for health. The stoves allow us to have a pleasant sensation of homogeneous heat even if the air temperature is relatively low; in a way it’s the same thing that happens in the mountains when, with the sun on your face, you are in your shirt sleeves, even if the air is at 5 ° C.

The stove produces about 80% of the heat by irradiation and 20% of the hot air at low temperature. In addition, if you lean on the radiant surface, you will benefit from a pleasant warmth to the touch. In fact, the surfaces can reach 40-80 ° C, but being in masonry, they do not burn.

Types of stoves and their main characteristics.

Metal pan.

The open chimney allows direct contact with the fire but burns the low temperature firewood. The metal burns the dust which is distributed in the room with large amounts of hot air.

To make wood last longer, there is a practice of smothering the draft and reducing combustion air. If combined with damp wood air quality is seriously affected.

The process produces large amounts of fine dust and toxic substances (nitrogen dioxide). The soot produced by unburned gases accumulates in the flue gas pipe and creates a fire hazard.

Pellet stoves.

They have high performance because they recover the waste heat from the smoke to generate more heat. If they are made of metal, they produce ash dust and uneven heating of hot air.

They have good combustion and produce little pollution; in fact, after the first few minutes, you cannot see the smoke coming out of the chimney.

Thermal inertia masonry stove.

It is based on the accumulation of heat to achieve a high thermal inertia. They consist of a combustion chamber and ducts through which the smoke circulates.

Produces clean combustion thanks to combustion chamber. Essentially, it accumulates heat in the mass of the masonry of the stove and gradually releases it into the environment.

If clay is used in its manufacture, the effect is enhanced by the thermal inertia of the clay itself. It is a heating system that is completely independent of fossil fuels or energy networks and is not vulnerable in the event of power outages or financial problems.

Dry firewood for stoves.

For all types of stoves, it is recommended to use dry, chopped wood, preferably stored away from rain for two years. If it meets these conditions, it will produce little smoke and soot when burned.

This aspect also influences forest management. Avoid cutting down trees as it is sufficient to cut dry bushes or dry branches.

Modern masonry stoves, with calibrated combustion, have an efficiency of between 78% and 90%. They are used only one or two hours a day, about three hundred hours a year, against 2400 hours of a metal stove, which operates on continuous fire for sixteen hours a day: thus the dangers decrease proportionally.

In masonry stoves, only dry, chopped and split wood is burnt and stored away from rain for two years. This way, it will have a humidity of less than 18% and will burn efficiently, or around 4kW per kg, with little smoke and little soot. Seasoned wood should always be used in all appliances, from fireplaces to stoves. One-year-old wood, or worse yet wood cut in the spring and burned in the fall of the same year, contains about 35% water and each kilogram gives about half, or about 2 kW / kg.

The temperature is uniform, the air does not move much in the room and it maintains around 50% humidity. They are much safer because, apart from the door, the stoves do not burn. In addition, they produce little pollution: after the first few minutes, you cannot see the smoke coming out of the chimney or there are bad smells, and this is the sign of good combustion.
