Scope The manufacturer orders the evaluation of ineasurements on flue gas emissions and efficiency. Basis for the evaluation are the results documented in the test report no. H-A 1190-03/11 dated 2011-07-15 and the values according to declaration of manufacturer.

Basis of test DIN EN 303-5:1999-06 Heating boilers for solid fuels, hand and automatically stocked, nominal heat output of up to 300 kW

3 Test documentation Test report no. H-A 1190-03/11 dated 2011-07-15 on the test of requirements of the heating boilers type BioWIN (Summarized Validation) Values according to declaration of manufacturer, dated 2012-03-07

4 Description The heating boilers type BioWIN 450 Premium and BioWIN 450 Exklusiv are intermediate sizes according to DIN EN 303-5 and not tested on boiler performance by the test Iaboratory. The boilers were type-tested according to the requirements of DIN EN 303-5:1999-06 by the test laboratory for firing and heating technology of TUV SUD Industrie Service GmbH. A detailed description of the boilers is documented in test report no. H-A 1190-03/11.Page 3 of 4

Measurement and analysis methods The emission-values are calculated by interpolation by the manufacturer. The calculation of the emissions data is carried out with reference to 10 % 0 2

. The analysis methods are used at the test on the boiler performance of the heating boilers type BioWIN.

5.1 CO 2 / CO measurement For the CO 2 / CO measurement a calibrated device on the principle infrared absorption was used. The values are measured continuously during the complete test period. The calculated mean values for CO 2 / CO emissions are 13.5 % / 41 mg/m' (maximum load) 9.2 % / 113 mg/m 3 (minimum load) 5.2 Unburnt Hydrocarbons For the measurement of unburnt hydrocarbons a calibrated device on the principle of flame ionisation detection (FID) was used. The calibration was performed on the basis of propane (C 3 11 8 ). The values for unburnt hydrocarbons are measured continuously during the complete test period. The calculated mean values for unburnt hydrocarbon emissions are 2 mg/m' (maximum load) 2 mg/m' (minimum load) 5.3 Particulate emission (dust) For the measurement of the particulate emission (dust) a calibrated filter instrument and a calibrated balance were used in a gravimetric procedure according to CEN/TS 15883, annex A. The dust emission was measured 4 times in the test period. Each period of measurement takes 30 minutes with a constant volume of the sample. The calculated mean values for dust emission are 17 mg/m 3 (maximum load) 15 mg/m 3 (minimum load) 5.4 Efficiency The test was perPormed by TOV SOD Industrie Service GmbH using a test rig according to picture A.2 of EN 304:2004-01. The values are measured continuously during the complete test period. The calculated mean values for direct efficiency are 90.7 % (maximum load) 89.3 % (minimum load)Page 4 of 4

6 Summary The emissions and efficiency are measured/calculated

- in Iine with EN 303-5 regarding the determination of inorganic and organic

gaseous or particulate air constituents,

- using existing procedures in the quality system of the Iaboratory for firing and

heating technology,

- using calibrated measurement devices and

- using interpolation method as noted in clause 5.1.3 in the standard The type test on the heating boilers type BioWIN is documented in test report no. H-A 1190-03/11 dated 2011-07-15.
