Dobio sam prof proracun potreba moje kuce kroz godinu.U obzir je uzeta namorska visinazemljopisni polozaj kuce i nivo izolacija.Kolektor 2 solarne ploce spremnik 800l i pelet izvor topline 20 kw. Rezultati su ovakvi:

total fuel and el consuption of system(Etot) 18,577kwh
toal energy consuption(Quse) 14,244kwh
system performance o.77
overall solar thermal energy
colector area 4m2
solar fraction total 13,7%
solar fraction hot water 31,1%
solar fraction building 3,6%
total annual field yield 2.138kwh
colector field yield relating to gros area 534.5kwh/m2/year
colector field yield to aperture area 593.9kwh/m2/year
max fuel savings 521,5 kg(pelets)
max energy savings 2,607kwh
component overview
boiler pelet boiler 20kw
total eficiency 72,6%
energy from to the system (Qaux) kwh 13,456
fuel and electrical energy consuption (Eaux) 18,547
energy savings thermal kwh 2,607
hot water demand
volumen with dravl/daily consuption l/d 194
temperature seting 50 c
energy demand 3,116 kwh
pump space heating loop pump
circuite presure pump 0.025 bar
flow rate 1,509 l/h
el energy consuption 19,6 kwh
pump solar loop pump
flow rate 144 l/h
fuel and electrical enrgy consumption (Epar) 9.7 kwh
storage tank Bufer tank 800 l
heat losses 474 kwh

to je to strucnjaci

1 kg peleta je otrilike 4.5kwh pa ispada da trbam 4150 kg peleta kroz godinu
valjda sam dobro izracunao molim ispravite me ako grijesim hvala
moj savjet je da NEkupuješ kolektor već heat pipe cijevi. imaju veću iskoristivost i griju na nižoj temperaturi. za taj sistem ti treba i manje solarne tekučine jer u cijevima ne kola solarna tekučina več imaju svoj vlastiti fluid.
