This fan works better than the eco fan as it used a coper pipe heatsink for cooling it will always remain cooler (thus working) no matter where it is placed on the stove. The ecofan (I purchased) if placed at the front of the stove eventually heats up the heatsink and stops working (no temperature difference either side of the peltiers) the ecofan depends on the cooler air coming from the back of the stove to keep the heatsink cool.
I used multiple peltier plates wire in series basically to save money as peltiers (TEC or TEG) which are specifically made for thermal electric generation cost about £15 each, mine cost £7 for the pair !
