Eagle Shield’s Hidden Energy-Guzzlers- Part 4: Where your money is really going

Uncategorized Apr 04, 2013 No Comments

So far, on our journey toward the reduction of unnecessary energy use, we have dealt with three of our ten energy guzzlers: the refrigerator, the flat-screen TV, and the air conditioner. This blog deals with an energy guzzler that, to me, came out of left field: the notorious swimming pool and hot tub filter pumps. No kidding. How often do you stop and consider just how much energy it takes to keep your pool and hot tub clean?
My answer? Never. That’s because we hardly use them, yet pay the same amount as if we were using them 7 days a week! Here’s how it breaks down for me:
• Swimming pool filter pump: Runs approximately 8 hours a day and costs me an average monthly cost of $37.00
• Hot Tub filter/pump: This is an older unit (115 volt) which is set at 100 degrees, and found that it is costing me $43.00 a month, even with an insulated cover. That’s in a warm climate.
So both units are running me around $77.00 a month. In the summer months we use the pool on a daily basis and rarely use the hot tub. In the winter months (gets down into the 40’s) we often use the hot tub but rarely use the pool. When we considered the “ROI” (return on investment) for these appliances, based on their usage, we decided to make some changes.
First of all, the hot tub. How can something so much smaller than the pool cost more to run?? I have a buddy who used an infra-red gun and showed me that heat is leaking out from my tub onto the deck. In other words, the deck lit-up. I’m unintentionally heating my outside deck. Upon inspection, we found that the Mickey-mouse insulation that originally came with the tub was mouse-fodder. He helped me take two-inch foam block and glued it to the insides of the tub housing, which made a huge difference in keeping the heat in. No more heating the deck.
We also decided to just shut-off the hot tub during the summer months. Finally, we were told when we did use the tub, to not leave the jets on unless we were using the tub. It seems that the jets like to inject COLD water into the tub which, in turn, needs to be heated. We think that we can shave around 50% off our hot tub energy bill.
Next, the pool. I found that running the pump 8 hours a day doesn’t significantly improve the cleanliness of my pool, but it does significantly increase my energy bill! I set my pump to run no more than 4 hours a day during the summer and we’re still trying to decide if we want to shut it off completely, or run it for only a couple of hours in the winter. Also, I have an older model, power-hungry, single-speed pump and am considering moving to one of the newer variable speed ones. I have found that the cost of the new pump would be well worth the investment, and along with shutting the pool down in the winter months, will save me around 40-50% of my annual pool bill.
So…if I can reduce this energy use by 40%, that’s a $30 monthly savings. I’d rather spend that on lunch after church one Sunday than give it to PG&E! Come to think of it…the money I will be able to save by reducing the energy usage of all 10 of these energy guzzlers could be enough to buy us lunch every Sunday!
