Hi, I have modeled an air to water heat pump in energy plus for heating using "Coil:WaterHeating:AirToWaterHeatPump:Pumped" , WaterHeater:Mixed and a fan.

When I run the simulation, the "Water Heater Use Side Heat Transfer Rate" is significantly less than "Zone Air System Sensible Heating Rate" which is what is supplied by the system to the zones.

I do not understand how it is possible that these two outputs do not corresponds each other.

I will thank you if you share your idea for solving this problem.
