JASPI ECONATURE - POWERFUL & EFFICIENT
Econature 40 is a powerful, clean burning solid fuel boiler for the most demanding applications.
This new generation wood gasification boiler has a considerably higher efficiency than that of a conventional wood-fired boilers. The Econature boiler offers 91% efficiency, which brings the solid fuel burning close to the best new oil and gas boilers.
The boiler output power is 40 kW and the large wood furnace takes around 30kg of 500mm logs to produce a massive 100kW of heat in one burn. This takes only 2.5 hours. Econature must always be connected to a thermal storage tank for recharging (1500L to 3000L recommended).
DESIGN
Econature's ceramic burning grate and afterburner guarantee a very high combustion temperature. This high- temperature burning is a clean combustion process that produces little tar and very low NOx emissions. Moreover, the process provides the highest release of energy by wood burning.
The combustion process happens on ceramic fire crate whilst a blower fan provides balanced and optimized downwards draught. Gasification of firewood begins at a temperature above 100°C and as soon as the temperature exceeds 280°C, useable heat and burning gasses start to be released. Secondary combustion begins at a temperature over 600°C. This bright white flame can be observed through a small window at the lower part of the boiler. This high temperature combustion reduces firewood consumption and the amount of ash.
Clean combustion and the obtained environmental certificate also makes it possible to use the boiler in densely populated areas.
AUTOMATIC OPERATION
Once firewood is completely burnt, the blower fan stops automatically so that you will not have to go to the boiler room after the last filling of the furnace. The boiler pump thermostat will control a charging unit mounted between the boiler and the thermal storage tank and ensures that water entering the boiler from the thermal storage tank is hot enough. Also this will turn off automatically once the boiler has cooled down.
Boiler overheating protection will switch off the blower and this in turn will stop the burning process.
You can also use the blower thermostat manually to stop the burning process if no more heat from the boiler is required.
Econature has been tested as per EN303-5 and meets or exceeds all the requirements of the standard. This boiler does not require thermal safety valve, connection to mains water or additional cooling coil.
EFFICIENT
The EN 303-5 testing demonstrated an average efficiency of 91% in a five-hour combustion cycle. It is however important to keep in mind the quality and moisture content of the firewood. The moisture content should be less the 25% to achieve better efficiency. Operation and maintenance are done at the front and on top of the boiler. Sensors, gauges and controls are located on the front at a convenient height.
It is essential that this boiler is connected to a thermal storage tank, the recommended that the size is between 1500 and 3000 litres. The connected thermal store must be large enough to handle at least one full load of logs, up to 100kW, this is achieved with a 1500L thermal store. If several loads are burned without taking the heat out from the system (radiators / DHW) then the thermal store must be bigger.
