Heaters are more efficient running at hi vice low speed. Some units allow you to adjust the pressure/flow switch on the heater unit. It may take trial and error.
Please help with my decision on a pump

I'll have to check it out...where would I find that, simply search mas985?

Well...I'm sure it'll run alot in the early and late season....and hopefully not need it as much during the hotter part of the summer...my pool will have direct sun almost all day and will always be covered with a solar blanket when not in use...

Thanks for the input....I appreciate all the advice I can get! Havent seen anything in the research I've done about the 2 heat pumps I'm currently looking at (about adjusting the pressure/flow on the heater), but I'll keep looking.
Yes, by that user name, there is a link in his signature. You will have to use your existing pump and pressure data to try to calibrate your head loss and then see how other pumps would perform.
I have the Hayward Power Matrix 2 speed 1HP pump. At low speed the flow is fine for my heat pump. If I also send water to the solar panels then I am on the border with respect to flow rates. This would be at low speed. If I start the pump off at full, turn solar on and then switch to 1/2 speed it almost all works ( heat pump, solar, but not salt). Remove solar and then at half speed both salt and heat pump work. Really nice pump but I miss self priming and it is noisy at full speed ( well no worse then others but it is silent at 1/2 speed).
