Air to water heat pump for heating

Hi, I read about Air to water heat pump and I Insert Heat pump water heater in Zone equipment and put water heater on heating plant loop, but after simulation I have 0 values for heating and only water use, how could I separate two results, I need to know both uses (Hot Water and Heating)?

Exist a better solution for model I need to do, explained below?

Supply side: Air to water heat pump combined with a boiler hot water, Demand side: HW coils.

Have you tried looking at example files? Also, what objects exactly are you using?

There are several example files that use Coil:WaterHeating:AirToWaterHeatPumpobjects.

You can find the example files in C:\EnergyPlusV8-8-0\ExampleFiles, and the "ExampleFiles-ObjectsLink.html" document in this folder lists the objects used.

Hi, thanks for reply. I need to simulate something like this image where heat pump provides heating for hot water coils and boiler integrate heating when is required. I follow this and this following this but it seems not working, it shows me 0 heating loads and all on water sys
