I am trying to model a Heat Pump Water Heater in OS 2.9.1
I keep seeing high peak electrical use in my model from water heating systems. When I try to track the HPWH performance by exporting the variables for heating rate and electrical energy, I am seeing a COP of only 1. If I use the default settings when I first add a HPWH to the zone, all I see is the gas energy at 80% efficiency. When I track heating coil variables, I do not see the HPWH coil. Is only the tank functioning? I'm confused as to why I'm not getting better performance than a regular electric water heater. How do I export the HPWH coil electrical inputs and heating rate so I can verify that my COP of 3+ is actually being modeled?
I used the same method shown here to set up my HPWH:
