[esp-r] Re: Simulating UFH vs radiators

[Achim Geissler]

Dear Bob

not being attached to the originators of the program, maybe it is for me to
say: ESP-r can do practically anything. However, "not too much effort" can
only be expected for the "usual" things.

I understand only half of what you want to do (the abbreviations are a bit
terse for a "non-native english speaker"), but ESP-r has many possibilities
in regard to modeling long wave radiation (I assume you mean with
"radiators").

So, maybe explain what aspects IES can't cover, give more detail in regard
to where you see simulation-wise problems and maybe simply try it out - it's
readily available, after all. Probably, ESP-r can do it. But not necessarily
without (too much) effort.

Subject: [esp-r] Simulating UFH vs radiators

Dear list,
I'd like to run some simulations comparing the effects of using  
radiators at lower temperatures with UFH, viz. trying to see how  
oversized rads at what temperatures have to be to deliver the same  
level of warmth as UFH. I have done some monitoring of heat pumps  
retro-fitted in houses with rads where the output temperatures from  
the hps are nowhere near as high as should be expected, yet the houses  
are adequately warm......

I am reasonable well up on IES VE, which I don't think can do this  
simulation, so can ESP-R (preferably without too much effort)???
