How to model an air to water heat pump?

Hello, I am a beginner in OpenStudio and EnergyPlus. I want to simulate an ASHP (air-water) for space-heating use and DHW use in the OpenStudio/ EnergyPlus, how can I do it?

I am considering the building is a small residential house and zoned with only one room/ thermal zone. Not considering any internal heat gain such as people and elertric equipment, and to maintain the indoor air temperature as 21oC whole year under UK climate data. The hot water from the heat pump is supplied to radiator in the first model and change to floor heating in second model. What schedules should I input and how can I create such HVAC system? I appreciate any help!
