  1. Broken paddle...

    2P or not 2p, it would help it fill quicker.

    Don't worry, I am, it's banter. Except for the bit about ecofans actually working. However if my experience shows it works and yours shows it doesn't, what else is there but the actual facts, determined by science.
  3. Eco Fan

    Dismiss? Aw didums! Such emotive language for a scientific debate. No, I question! Here, have a tissue, dry your eyes now lad! The capacity to act as a heatsink is down to the mass of the object, the capacity of that mass to disperse the heat as it accumulates is down to its surface area, colour and air moving across it. So we have a solid flat iron lump and a skinny funny lump with a greater surface area and a steady breeze blowing across it, which do you rationally assume would disperse accumulated heat quicker?

    By but but, of course that will only work until the flat iron comes up to temperature, it not having fins cooled by a fan. Another pan of water would have the same effect, better use of the heat. Unless you actually want to use the flat iron.

    Spot on, what I've said too. But I also consider , because it increases the airflow around the stove, it takes more heat from the stove that would normally go up the chimley. Hence the effect on my kettle. Maybe it's more effective on my stove at home because the stove is sitting in a hole with a 4" gap at sides back and bottom, 12" above.

    In Lancashire there are also Muffins and Oven Bottom Muffins, and latterly a Frisbee, an 8" dia. Tea cake. Wonderful, filled with Bacon, mushrooms and black pudding. Mind you I was brought up when Muffin the Mule was considered to be bestiality.

    The problem is, no one has given a satisfactory answer. Comparing the wattage of the fire, yes 4kw, has no relationship with the wattage needed to drive the fan. Other than the hotter the fire, of whatever kw, the faster the fan, until the bimetal strip lifts it and cools it down.
  9. Eco Fan

    It' It's both. I think it travels through the peltier cell, this creating electrickery, sending the heat the other way cools the peltier cell , as in car cool boxes. Of course conservation of energy means that some becomes electrickery, some is dissipated by the fins. But not zero. Therefore correct. Pedantically speaking. IMHO.
  10. Eco Fan

    Yes, but repeating something doesn't make it right. Heat travels up the mass of the fan by conduction, some of it radiates away, some of it conducts into the air, this is of course assisted by the fan causing a greater air flow over the fins.
  11. Eco Fan

    Ooh, mr picky pedant. I put it simply for the hard of learning. I know the heat travels up the mass of the fan by conduction, it then leaves the fan body by radiation and conduction into the air. But we do put the fan on to the stove to remove heat from it that would otherwise be pushed up the chimney by the surrounding air pressure of roughly one atmosphere. This theory is demonstrated in this thread, I'm low down and grounded, being Cool, while others are way above me, being full of hot air. Did you post something earlier, I must have missed it. Try shouting in bold capital letters. ;-)
  12. Eco Fan

    But that's not what he said is it. He didn't say nothing happens when it's going slowly, that's your surmise.
  13. Eco Fan

    I do not need to experiment, I'm happy. And you really backed up what I was thinking, there is a formula for such things, not just "I think" and "probably".
  14. Eco Fan

    Dear anyone know how to calculate how much fluid a propellor moves, at a given speed, size and pitch? This would tell us how much air an ecofan can shift. Any engineers got a book of tables?
  15. Eco Fan

    The air above the stove is moving faster than by convection. It's moving horizontally. Away from the stove. Taking the heat with it. So cool air is constantly being drawn in to replace it. That is then warmed and blown away. Constantly but slowly. Cooling the stove. So the kettle doesn't boil. By your reckoning the effect of a static fan on the kettle would be the same as the moving fan. This is not the case. Kettle boils. Btw an insignificant force, applied continuously, can move mountains. A little drip in same place, wears a big hole. At least you now agree there is some effect, that there is a force.
