How electrically efficient are these gridseed pods when used as a space heater?
I know they are not an "efficient" heater so I am not arguing for that use. Please assume for this question that all other heat in the house is electric and that heat is required for 9 months of the year. Also, please ignore purchase cost of the pods versus buying an actual heater. This info could influence miners who live in cold climates when considering a voltage mod.

My guess is that 75% of the electricity used ends up as heat. Do you think my guess is high or low or about right? Probable less waste heat ratio at low wattage (stock LTC) compared to high wattage (dual mode).

if its hashing away and using 20w itll be producing 20w heat. hashing produces heat it doesnt turn it into another form of energy. ok there a small loss in the fan and the leds. but its all gone out as heat if not from the gridseed chips themselves then the voltage reg crystals and other pieces.

You could measure it putting it in a metre by metre box giving a 1m cubed volume area, of airt at room temp make sure only the grids are inside disconnect the fan and power it up and time how long its takes to rise the temperature in the box by 1 degree. take an ampage reading of just the grid seed, not the power convertor or from the wall or psu but at the grid. find the energy co efficient of air compare contrast and youll find your answer.
something like that anyway

Although a bit more expensive power bill wise, GPU's would be perfect for your 'space heating' needs Wink

And they are becoming cheaper and cheaper now too, I believe.
