Dear Mika Yoshinaga, 

Thank you for bringing this to our attention.
The units of those particular flue loss parameters for the Type534 (with
out plugin) should be a default of [kJ/h.K]. The version with the
plug-on does indeed have this labeled correctly. If you need a copy of
the proforma, please send me a private message. 

Thank you, 

Matt

I use TESS Type534, vertically cylindrical storage tank with immersed
HX, and face to a small problem with "gas flue losses". From what I
understand, the gas flue losses is for the modelling of heat loss
through an immersed gas pipes for boiler or some kind of heater.

parameters, there are some "Flue loss coefficient for node" and their
unit are [W/m2K] or such order. If so, the area of the gas flue pipes
also need to be set, with unit [m2], but there isn't such a parameter.

coefficient for node" has the unit [W/K] correctly. This is more
reasonable, because it is explainded as "for node".
