Once again, let me preface this by saying how much money you guys have saved me over the past year. Thank you.
I am trying to decide whether it is worthwhile to change my 2 HP pump to an intelliflo. My utility is offering a $400 rebate but it expires Dec 31 so I am trying to make a decision in the next week or so.
I calculated my current yearly electric cost at approx $650. My electricity is 15 cents kw/h. Pump is 2 HP, 1.1 SF, 10.4 max load amps. If my math is incorrect please point this out. A picture of my pump is here:
According to the pentair website, my cost to run the intelliflo would be about $150 per year (assuming running at 1000 rpm and 1 turnover). I have no water features except a spa used rarely. The spa is elevated from the pool ~2 feet with a waterfall between.
Are these numbers realistic? Am I one of the special cases that really could see 80% savings with an intelliflo?
