doodoo:
Thanks for the info on this to both of you. SDS I'll do the math on my optima and see what I get out of it. I know that a recirc pump is always a good idea what with low amp draw (1/10th of a regular pump) which is what is on my Optima and most other reputable brand.

But what I am very surprised at is the difference in motor efficiency and pump efficiency. I had not realised that they would be calculated seperately. I just assumed that they were one and the same. Does make sense though.

Perhaps in a few years this technology will find its way into spas.
