Hello everyone,
I am simulating a wall radiant heating system with an air-to-water heat pump. Unfortunately, DesignBuilder only allows the air-to-water heat pump to be used for cooling, while for heating, I am forced to use the "ASHP Air-to-water Heat Pump. Water convector" template.
However, with this setup, I am unable to maintain the indoor temperature setpoint. I noticed that by significantly reducing the hot water storage tank (since it does not exist in reality), the heating coil provides thermal power only at the very beginning of the simulation, then gradually decreases to zero.
Has anyone experienced the same issue? I am available for any clarification.
Thank you in advance
