Intergas 36/30 MWT - Rad Sizing

[machineage]

Posted this on another forum - but thought I would try here as well:


OK - I just completed the heat loss calcs with Stelrad Stars.

However I just realised Stars uses a default MWT of 75°C. This can be manually changed which will then re-calculate the figures. I'm not sure what Delta T figure it uses for sizing the rads though?

I will be using Stelrad Softlines - and have the outputs at Delta T 50 - 40 & 30. I also have the table to apply correction factors in 5° steps.

What would be considered the best balance between return temps - rad sizing - MWT for the Intergas 36/30?

Thanks!
