So can someone explain to me about the bypass valve for an electric heat pump pool heater. If the bypass valve is in the off position, does water still circulate thru the heater?? Does the water automatically start running thru the heater once you turn the heater switch to on? May be a dumb question but...still learning all this.
I had to finally call someone to come out and look at why the heater was not working. It ended up being the capacitor. While there he asked why the bypass valve was on. I said I thought it had to be on for the water to flow thru the heater to get hot. He said no. That by it being on, more water was flowing thru and taking longer to heat up? I don't know enough about this to question him, just took his word. So now that I have had time to think about it I am even more confused. If more water was flowing thru, wouldn't it heat up quicker. Maybe he said the opposite and I misunderstood. With the bypass valve open maybe 50% of the water does not run thru the heater and it takes longer to heat up?????
