How to choose your wood for fueling

Do you like the looks of your fireplace? If your fireplace is new, most likely the answer is affirmative.

All new owners should know, however, that the beauty of a fireplace depends very much on how it is maintained. And one of the determining factors for the appearance and functionality of the fireplace is the type of wood you are using.

Our recommendation is to not ignore a very important aspect – the wood can make the difference between an enjoyable experience and one where you have to spend time cleaning the windows or to perform maintenance and repairs.

Most importantly, what you need to know is that the wood is kept dry, ventilated naturally. The size should be appropriate to the type of furnace used. The best wood is hardwood – oak, beech and acacia, because they burn longer and with smaller flames. Another very important aspect of your fireplace is operating mode of the outbreak, more specifically, the maximum amount of wood that can be consumed in a given period of time. If you overload the outbreak is not a neglected risk that it becomes hot from the outer structure to the displacement of the outbreak’s components.

Zaconex outbreaks wood

Regarding Zaconex fireplaces, they are among the most durable and effective on the Romanian market and only use well dried wood with a moisture content of 20%. Using damp wood leads to the formation of sulfur and smoke. We are recommending pieces of wood with maximum circumference of 27 cm and 25 cm long, made of soft beech, oak, birch or fruit tree stored dry at least 2 years.

Completely avoid the use of other fuel sources, such as painted wood waste, debris particle board, plastics, cardboard, wallpapers or others, also the wood that is not dried enough.

Recharging wood interval is 45 minutes. It’s good to consider the calorific value based on the fuel weight. This is different from one kind of wood to another, so please find below the example we used on firewood that was stored for 2 years and has a humidity of 16 ÷ 20%. Here is an example of calculating the hourly fuel consumption:

  • Heating power resulting to 1 kg oak at a yield of 76% = 4,2 kwh x 0,76 = 3,192 kwh;
  • hourly consumption: at nominal heating power 6 kW = 6: 3,192 = 1,88 kg / hour.
