Flow too low for heater...

[baundy]

Quick post: My heater is saying that the water flow rate is too low to operate when my pump is running at 1800rpm. The max on it is 3450rpm. Filter doesn't need cleaned out. Pump is a good 50 feet (maybe more) from the skimmer. Any thoughts? Thanks!

What kind of heater gas or electric? For gas 1800 is too low.

Quick answer: increase RPM.

That's what I was kind of getting at: Is it as simple as the water flow really just isn't enough at 1800rpm or it SHOULD be running at 1800rpm so something else must be going on.

No one has jumped in to say that 1800rpm should be enough, so it must not be. I'll ramp up the RPM when I need to heat the pool I guess, haha.

2400 rpm is more typical to have a good flow through a heater.

Did you increase it? What number did you go to?
