Using pump with lower flow rate than stated in a chiller

[MbmC]

Does this reduce chiller efficiency?

For example. Arctica 1/3 DBE-250 is rated 480 - 2400 GPH. What happens if I run an Eheim 1250 connected to it, which is rated at 320 GPH?

yes, i believe it shouls lower ur chiller efficiency. thus takes longer time to chill to meet your desired temperature.

The theory is that with lower flowrate, less water is passed through and chilled within the same amount of time.

I am using 1/4 HP (Model DBE-200) with Eheim 1250 for my 3ft tank.. So far look ok... except need to clean the pump every 3 to 4 month.. cause I am using the eheim filter at pump inlet.. I found the chiller efficiency drop via debris build up trapping in filter wool... my temperature set to 26C... otherwise so be safe... In other words depend to our tank sizes and heat induce in our tank also critical...

try to calculate using chiller calculator supply by JBJ... Add more buffer to your input so that we will not under estimate the chiller output..
