Have you measured the volume of your bathtube and seen in how may seconds it is filled?. In my house I can fill a vessel of 10 liters in some 55 seconds not 10. Those flowmeters are for the main water connection. What's their nominal diameter?- compare it please to the connection to the E-cat Have you calculated the speed of water flowing through the E-cat? Or in the connection pipe? Something is not OK here Peter
