So I just started looking into purchasing a new pump to save on electricity costs. So i'm really in the beginning stages. But here is the research I've done so far. And please correct me if something is inaccurate.
This is the pump we currently have:
A.O. Smith Round Flange 1 1/2 HP Full Rate Motor. (K48M2N110C1)
From what i'm seeing this pump runs at 1.5 horse power. Which converts to 1118 Watts @ 5-6 hours a day.
Paying .17 per kWh. Comes out to roughly $1 per day.
When I spoke to a employee at Leslie's Pool Supply. He claimed this pump was costing me between 40 to 50 cents per hour. So clearly he was full hot air. Correct?
After reading a number of other posts that had similar questions. our pool is 23,000 gallons (Pool & Spa). We NEVER use this pool. We haven't used the spa in about 15 years, nor do I personally know if the spa even works. We never heat the pool either. But that doesn't mean in the future we won't be using any of these functions later on.
The Rep also pushed on getting a Variable Speed Pump (Intelliflo, and Ecostar). Claiming that these pumps only cost around 3 to 8 cents per hour. They also just happened to be the most expensive VS pumps that they sell.
So in terms of efficiency, are newer pump really more efficient than older pumps? Or is the because variable speed allows you to pump at a wide variety of speeds, that allows a person to set the horse power to a lower speed in order to draw less power?
Also after reading a lot of mixed reviews. I've really hesitant on going through with the whole thing.
Edit: In the city of Burbank. They are currently offering a $400 rebate on variable speed replacement pool pumps only.
