    I have an application where I want to use a heat exchanger. The heat exchanger will exchange heat between the boiler return and the water heater inflow. I want to use a shell and tube heat exchanger also known as a pool heat exchanger because of the lower psi loss and because I can spare the space. I realize that brazed plate heat exchangers are more commonly used for this application. I have not been able to get a definitive answer regarding weather or not shell and tube heat exchangers are rated for potable water.

    Does anyone have any information regarding pool heat exchangers and potable water?
