ᐅ Heating load calculation or room heating load

Hello everyone,

We are currently dealing with heating. It will come down to a ground source heat pump. The underfloor heating and the pump now need to be optimally configured. The Energy Performance Certificate (EPC) here is more for official purposes rather than active use. So a proper hydraulic balancing is definitely mandatory.

Now it’s about the sizing of the heating system. For example, Stiebel Eltron offers a heating load calculation. However, this is probably not a "room heating load" calculation. I think it is more of an overall calculation. What is the difference between heating load and room heating load? Do both need to be calculated independently, or how should this be handled? Is it enough to have just a room heating load calculated?

I would appreciate some clarity in this jungle, thanks!

Remove one zero, and that’s about what a room-by-room heating load calculation plus underfloor heating design costs net with specialized building services engineers. The fees your office is quoting are absolutely exaggerated.

Do you have any other recommendations?

I shared my recommendation for the building services engineer two pages earlier:

I am very satisfied with his work.
