using water flow to control pool heater

Hello,

What do you think about the following setup for my heater.

1) Plug the heater into a constant power supply.
2) Have the pump on a timer that runs for 8 hours a day.
3) Set the thermostat on the heater to desired level.
4) When the pump is on the heater will come on but when the pump is off the heater will turn off.


I just want to make sure that water flow into the heater will properly turn the unit off and on.

thanks

Forgot to mention I have a Hayward H100ID1 (propane). In case that matters. I read the manual and got conflicting advice from it. For example it does have a switch that turns off the heater if water pressure goes down, I could not tell if it actually measures flow. But on another page it states that: "If remote operation is required, the heater should be controlled through the thermostat only." and "Do not operate the heater without water flowing through it."

My pool guy said it was OK but want to get second opinions.

thanks!

It does have a pressure switch which will turn heater off should water stop flowing, you're ok with setup.
