Analysis of the main parameters for the right choice of a pellet stove: cost, power consumption, technical data

On the market there are numerous models pellet-fueled, small concentration of sawdust from untreated wood and pressed, with different aesthetics and technology. Regarding the second aspect of verifying the existence of the basic prerequisites for installing the heater, such as the ability to place the flue and an air intake, that an air hole that must be connected with the outside of the ' home, the presence of an electrical outlet to start up and operation.

First you need to decide whether to opt for the type of air or to the water (hydro). This allows you to produce hot water for domestic use and for the radiators. The air oven allows you to spread the warm air in multiple rooms, after duct system. The dimensions of the room are important, in fact about 30% of the heat produced by the stove remains in the room, so if high power could make uninhabitable.

As pointed out by Annalisa Paniz, responsible dell'Aiel solid biofuels (Association of Italian energy agroforestry), in the booklet of the stove must bear the CE mark, an indication of the legislation under which the equipment has been tested, the power of the stove, the yield in terms of percentage, the value of emission of CO2 which must be less than 0.04% (the lower the value, the less polluter) and the name of the manufacturer who must be able to guarantee a capillary network of assistance on throughout the country, for annual maintenance.

What is the fuel consumption? The pellet normally has a calorific value of 4.6 kWh / kg. A stove from 9 kW with an efficiency of 87% in its operation at the maximum power consumed in one hour 2.25 kg, while in idling consumes 600 grams of pellets per hour. With regard to the average cost of heating we are at 70 euro per MWh compared with 90 euro of natural gas.
