I have 15 when input low. Not when full.
This version have 15.

i found code of exchange local hotFluid_energy = hotFluid_v * (hotFluid_t - hotFluid_minT) * hotFluid_heatCapacity local coldFluid_energy = coldFluid_v * (coldFluid_t - coldFluid_minT) * coldFluid_heatCapacity local totalEnergy = (hotFluid_energy + coldFluid_energy) * heatExchangerCoeff -- Exchange ...

hey at up side i used basic pump not fast pump

This simple 15C problem exsample
Up heater not work because have low heat input
Down work ok

This my working get energy.

i have a problem with heat swap can you tell me how its work? what formula you using to cout output temps to heat swap? in physics formula Temp=(C1*P1*T1+C2*P2*T2)/(C1*P1+C2*P2) T-basictemp C-нeat capacity of liquid P-amount of liquid in pipe in water energy counts as Energy=Temp in pressure water i...

This scenario not work now....
Errors while run.
