Hello,
I believe that it depends on the set point temperature fixed in the calculation of the energy needs and on the temperatures reached every hour in the building. My idea is that in the simulation with the heat pump, the air temperature in the building is not the same of that set in the simulation performed for the energy needs calculation

Hello,sirs
_______________________________________________
I simulate a ground source heat pump system for heating a DHWand building, the heating load of building was 5019kwh/year,i use a heat pump with capacity 8kw , and i use the relation q=mcp(Tin-Tout) to calculate energy delivered to the radiant floor and i found 14711,6kwh/year .I did not understand this result , building Just needs 5019kwh/year
Thank you
