FAQ

Question: If the surface of the circulator pump is warm to the touch, what might be the cause?

Answer:

A: Circulator pumps are generally used to circulate hot water. The temperature of the pumped medium is transferred to the pump, and it is normal for the pump's surface to be warm or even hot.
