[esp-r] slab-on-grade hydronic floor

[Ragnhild Haukland Løge]

Hello,

I have a simple model of a building with a solar heating system. The solar
heating system consists of the following components:

-simplified flat plate collector
-slab-on-grade hydronic floor
-variable speed domestic WCH pump

I have the following connections:
collector->hydronic floor
hydronic floor->pump
pump->collector

And containments:
collector: ambient air
hydronic floor: node within a surface: ground floor inserted into node 2
(within a concrete layer)

When i run the simulations with and without the plant network, I get the
same temperatures inside the building. Hence, it does not seem like the
solar heating system is contributing to any heat through the floor into the
building zone at all.

My question is: Does anyone know if I have to link the plant network in a
different way or if I may have overlooked something in order to get the
solar heating system to contribute to heat inside the building.

Kind regards,
Ragnhild Løge
