Heating System Higher Delta T's

Heating System Higher Delta T's

Heating System Higher Delta T's

(OP)
Does anyone have any horror stories about designing a heating system with a 60 degree delta T?  (180 degree supply T) I am working on a heating system that utlizes waste heat and to make the pay back better, I was exploring the possiblilty of higher delta tees.  This system will be installed in the NW and the design temperatures will not be that low (right around freezing).

I have designed many systems with a 40 degree delta T.  I have had no problems with these systems.  If there are performance or temperature control issues, please let me know.

Thank you.

Louie!

I don't see any problem in heating and controls.

Regards,

Truth: Even the hardest of the problems will have atleast one simple solution. Mine may not be one.

RE: Heating System Higher Delta T's

Just a question for you, have you had any problems in selecting equipment with respect to low water velocity.  Small pieces of radiation especially, or do you typically size smaller pieces for a lower delta t since it shouldn't have a great affect on your system performance?
