Berkane, 

The heat pump is also doing DHW and there are losses to the ground from
the floor. If you've connected things correctly, the energy should
always balance...

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

>> 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
