Domestic hot water energy consumption



Hi all,
I know it may be a silly question, but is there any component calculating the energy consumed by domestic hot water usage?
Thank you in advance!


Do you need a component for this, is it not enough to calculate the power to raise the temperature about 50 degrees C and maby some pump energy?


Hi Max,
Thank you for your reply.
For the simplicity of the calculation, the answer is not.
But for curiosity, I tried to find one in HB because as far as I know, the ARCHSIM has this function.



Use the “Ladybug_Residential Hot Water” and “Ladybug_Commercial Public Apartment Hot Water” components from Ladybug’s “4 | Renewables” tab. You need the output “heatingLoadPerHour” in kWh.
Modify its inputs to accommodate your building type.
