Hello! I have been trying to set up an energy model for thermal comfort in winter. Is there any way to set a (sub) surface on the wall as a radiator? Or is this type of heating system limited to what is available in the HB Radiant HVAC properties component, i.e. floor or ceiling heating?

Hello again, here a follow up. I have been digging a bit, but cannot find a proper sollution. I know in the HB legacy it is possible to select a “custom radiant surface” as input for HVAC system. With that you can control the “internal source” material. (see picture 1) [image] In HB 1.6.0 there …

Hey @AntonH , I would still recommend using the LBT plugin and this is not completely true: [image] AntonH: In HB 1.6.0 there is no possibility for a custom radiant surface, nor any posibility to set a the controls You can change the type of radiant surface (Floors, Ceilings, FloorWithCarpe…

Thanks for your answer @chris ! I did indeed find the possibilities as you mentioned for radiant slabs. However, what I am trying to model is radiators under the window, especially for housing (but even for offices) here in Sweden that is the most common practice for a heating system. This means th…

Thanks @MingboPeng ! It works now if I plug in the radiant surface as a floor, but when I model parts of the exterior wall to have a radiator, as pictured below, it does not recognize the small surfaces as radiant surfaces for some reason. It then gives the same error message as before. [image]

I noticed that when giving all surfaces a unique name and link it to the room, it actually takes the radiators now as separate radiant surfaces! Thanks for the help!

I discovered a new issue regarding this. I am testing now adding 2 radiators in a single room. Each radiator has their respective unique name, but now the error comes as follows: Surface RADIANT_CONSTRUCTION_1_D3B2EF09 is referenced by more than one radiant system–this is not allowed. Surface RADI…
