[Bldg-sim] Hot water requirements

[sambhav tiwari]

Hi All,
         In my project i have high speed disel fired boiler for
service hot water requirement how can i model it because in boiler
source there is no source  as disel.

And if the design is such that the hot water set point is 60C and it
if preated through solar collector and if achived 60C the disel boiler
wont operate and if not able to achive 60C  due to weather conditions
say till 50C then only disel boiler will operate to heat through
additional 10F then in such case how can we claim savings of hot water
in proposed case because solar heater is reducing the hours of
operation of disel boiler how can we quantify those hours.

I look forward for your valuable response.

Thanks
