At the same house we had an inground pool. We replaced the pool pump(which runs 7-8 hours/day). Again, the electric bill dropped $25/month.
On the other hand. I bought a new washing machine when we bought this house 12 years ago. The local dealer convinced me to buy a Fischer Paykel top loader because it would save me dryer time and put LESS water into the 40 year old leach field. The board died after five years. We went back to the same local store and replaced it with the exact same model. The board died again after six years. We replace that with a
Speed Queen. The board on that one just got replaced for FREE because it has a 5 year warranty. So, some of the ENERGY STAR appliances make sense to replace. Supposedly Speed Queen and Maytag make the best washing machines on the market. Speed Queen still makes a model with the dial analog controls. NO COMPUTER BOARD. If this one dies in a few years, that is what I will buy.
Does the SpeedQueen actually use sufficient water to wash clothes properly? Our GE does not. We have to add a large bucket of water to every load or else the top of the clothes pile in the washer will remain dry.
The problem is diminishing returns. If you go from a car that gets 10 mpg to 20 mpg it cuts the gas you use driving 1,000 miles from 100 gallons to 50 gallons. If you go to 40 mpg you will only save 25 gallons. The compromises you have to make in car design to go from 20 to 40 mpg are huge.
Is that Speed Queen analog for both washer and dryer, or just the washer? Yes, I want one of those!
