The purpose of this thesis has been to determine experimentally how good a peltier element is to convert waste heat from wood burning. Three different peltier elements were used in a comparison study. The comparison was mainly done to know how much power could be obtained from each element. Even, a circuit with a step-up function has been created to give a higher output voltage than the peltier element itself. The result of the experiments was a low output power, the highest value reached 2.18W. Also, the Carnot efficiency has been calculated for the three different elements and the efficiency ranged between 14 and 33%. From the circuit a constant 3.3V output was delivered. The main conclusion of this project is that furthermore Studies are needed in the material field because the elements available at the market today have too low efficiency.
