Hi! We are currently looking into the K-Star 5KW heater for our small 12 foot pool, but I've been finding some conflicting information on waterflow. We currently have a 1500 gph filtration pump (calculations say thats 25 gpm). Initially I was concerned whether this would be strong enough to trigger the heater. However when reviewing the manual for the heater, it has a spot where it states max waterflow at 8 gpm and higher would need a bypass. Does anyone have any information on this? I found it extremely odd as in another thread someone talked about ensuring a strong enough pump for this heater.
