Nice. That makes a lot more sense. It's still high, relative to more modern electronics, but nothing I would be concerned with. It turns out that a wireless printer in my house got turned and left on the same day as my pump got installed, and that accounts for about 10W of the change I saw. I am...

I really just enjoy playing with the system and trying to find the most efficient setup, water quality notwithstanding.

Just for the sake of discussion, you are not really accounting for all the variables with your contention. Yes, filters work better at lower pressure. However, without knowing the relationship of filtering performance versus pressure, there is no way to contend that moving less water (i.e. lower...

The VF can estimate pressure and has a filter pressure setting so that at a certain point, it will manage pressure and not flow. This solves the problem you mention. You can set it for whatever target pressure you want. I believe the manual suggests something like 11 PSI over clean filter PSI...

Even though it is off-topic, I thought I would add that I recently had my Triton FNS D.E. filter cleaned, which dropped the power usage from around 250W at 25 GPM to 170W at 25 GPM. Pressure at 25 GPM is now around 4 PSI according to filter-top meter. I think that before it was 8-10 at the same...

Certainly not, but the issue with that perspective is that when you take it across the whole house, it really does add up. In other words, 30W standby here, 30W standby there and all the sudden I am paying $20-$30 extra a month for pure standby power i.e. 100% waste. It offends my engineering...

That's my concern. In San Diego our top rate is now 39 cents/kWh with a blended average of around 25 cents/kWh. I am in an all out assault against standby power in my house because every standby watt I kill is x24 a day.

Getting back on topic, has anyone measured idle power draw of the Pentair IntelliFlo VF or other similar Pentair pumps?

I am sure you are correct, though I think you missed the point of my post, which is about idle power draw. I did not have a flow meter on the system with the old WhisperFlo so I was comparing roughly based on the amount of flow it took to get a similar spillover from my raised hot tub to the...

I just replaced my old WhisperFlo .5 HP pump with an Intelliflo VF (011012). First things first, the difference in power efficiency and sound is mind-blowing. Granted, my WhisperFlo is on its last legs, but the VF moves the same amount of water [edit:] for much less power. And, I can hardly tell...

I recently got my pool and spa remodeled and added a Pentair gas heater. I also have a roof-top solar heater. Presently the piping is setup to always go through the gas heater, though I can isolate the solar heater. My thought was to set it up so that I can bypass the heating system altogether...
