In addition to the stove type, a series of parameters must be taken into account when choosing the model.
The stoves require a vent to the roof (roof), as indicated in the RITE (Regulation of Thermal Installations in Buildings). It is normal to install the smoke outlet with a recordable T, respect the measurements and the maximum number of elbows allowed by the manufacturer, as well as normal ventilation of the room where the stove is installed, since some can be stopped due to lack of air. the combustion.
To calculate the power required to heat a given space, taking into account the 80-90% yields, and in an approximate way, it will be necessary to estimate 1 kW for each 10 m² for badly insulated houses and 0,7 kW for each 10 m² for those of Good insulation, provided they are normal heights. If the adequate power is exceeded, the consumption of biofuel increases more than necessary; and to stay short would force to work at maximum capacity during excessive periods.
In principle, most of these stoves are programmed to burn pellets, but some models allow and give assurance for the use of other biofuels such as nutshell, olive bone, etc.
The stoves have to be cleaned often, although only five minutes are required. It should be done weekly to remove the ashes and clean the glass.
Pellet stoves, which can replace old polluting boilers and expensive heating systems, require a much smaller investment than mounting a boiler.
Given the variability and high prices of gas oil, gas or electricity, biofuels offer stability and low prices. Even when the oil has been cheaper, heating with pellets was still cheaper than doing it with diesel or gas, when they go down, they do not proportionally, and when they go up, their price shoots up.
