hot water generation

hot water generation

(OP)
Where can I find hot water generation guides (not steam).
Application: central hot water system for large buildng.
It will be a electrical system

RE: hot water generation

I'm assuming that by "electical" you mean electric boilers.

Whether it's for domestic hot water or building heating, once you know how many BTU/hr the system needs, all the individual bits can be selected. ASHRAE will have tons of info, as will manfacturers of the various components.

yes electric geysers.

What ASHRAE code specific?

RE: hot water generation

The building system already exists and you just need boiler info for a retrofit option? I don't normally get too involved with the ASHRAE end of things (I do mostly industrial) so I just have some odds and ends of their literature. If you know the GPM of water circulating in the heating system, and the inlet & outlet temp across the boiler, then:

BTU/hr (boiler output) = GPM X 500 X delta-T

Then you would just flip the BTU into kW for electric boiler output. They're almost 100% eff, so input & output will be nearly the same.
