I was thinking that an efficient electric motor, such as a modern ECM motor, uses less electricity than a traditional motor, to do the same work. That's part of what I see in the manufacturer product descriptions. No? Agree that we can use a timer or remote (and we will).

John, I read the Grunfos literature about the Alpha pumps. Do you think they'd offer a material savings in electricity? Reducing 85W to (say) 40W, through the more efficient motor -- that's a savings of 45W per hour, times 10 hours of utilization per day, times 10 years service life times...

John, good question. I suppose I don't really know. Don't have plumbing plans. But big house (7200 square feet) Based on location of water heater versus furthest hot water fixture in the system, I'd say it's 100 feet each way, making allowances for turns as well as vertical distance. The...
