I have a 16 x 32 x 4 above ground pool which I'm trying to heat. We bought a solar panel which helps, but not all that much. So, I've put together a wood-fired "heater" which seems to work well (at least on it's trial day it raised the temperature from 68 to 76 in ~ 5 hours) but I would appreciate some advice from someone more knowledgable regarding the flow rate to my "heater." It is being supplied water from the pool in parallel with the return line from the filter. I've found that at full flow, it is returning water to the pool several degrees higher than the incoming temp. By full flow, I'm implying that the filter is outputting appr. 40 GPM, which is being split through a Y fitting between the heating unit and the return line. I've found that, if I restrict the flow to the heating unit to appr. 7 GPM, the temperature of the water being returned to the pool is ~ 95 degrees.
I'm wondering if it is more efficient to allow the full flow through the heater, yielding a lower input temperature on its return or is it more efficient to restrict the flow and accept less volume at the higher temperature?
Thanks... |
