published: 03/01/11, 18:53
What are the potential energy savings expected by better mixing the heated indoor air? And what would be the main drawbacks of mechanized blowing?

The technique consists in improving on the one hand the exchanges at the level of the heat diffusers (radiator, wood stove ...) and on the other hand the uniformity of the temperature in the heated rooms. Method: place a fan, regulated or not, on a radiator or near a wood stove.
Pitmix has shown, using measurements and time curves, that its boiler was running less when it put a fan on a radiator close to its thermostat: https://www.econologie.com/forums/ameliorati ... 10292.html
As a first approximation, I think that we can estimate a potential gain similar to that of heated floors which have the main advantage of the homogeneity of their heating (in addition to being compatible with low temperature) ... but for an investment .. .1 times lower!
Corrolaire: why the technique, so simple technologically, does not exist any more?
In terms of disadvantages, I see 2 for the moment: noise and power consumption ...
ps: we have had a ventillo near our wood stove for a few weeks. And even if it does not really reduce consumption, because there is no regulation, it improves thermal comfort on the other side of the room ...
