### 9.2.2. General results for radiant heating

These include, for each control circuit, a separate set of results, which includes collective data for the entire circuit and a list of manifolds in this circuit. The first line describes control circuit data:

- Source <source_name>

- Application <Heating / Cooling>

- Medium < medium_ name> – type of medium specified in the data table and, if medium other than water, concentration.

Collective data include the following fields:

Control circuit supplied from | type and name of supply source for the circuit |
ts/qs and tr/qr temperature | calculated or specified supply temperature for the CC, mean return temperature for entire control circuit based on flow rates and return temperatures in individual HZ’s of the control circuit | [0C]
Losses to be covered by RH | total heat demand to be covered by RH assigned to all HZ’s of the control circuit | [W]
Attained RH output | total output of all HZ’s of the control circuit | [W]
Heating water flow rate | total flow rate of heating medium in all manifolds of the control circuit, associated with both the attained output of floor heating and with losses to outside | [kg/h]
including make up of losses to outside | flow rate of heating medium compensating for the loss to outside (downwards and sideways). According to the calculation method applied, loss to outside is compensated by increase of heating medium flow rate determined during calculations. This field is designed to facilitate the estimation of the fraction of the flow rate determined by the need to compensate for losses | [kg/h]
Maximum available pressure | maximum available pressure of all applied for manifolds in the control circuit. Defined pressure is taken into account – calculated or specified by user | [kPa]
Water capacity of system | total water capacity of floor heating system: capacity of pipes making up the heating circuits and manifolds | [dm3]

Table of manifolds includes the following fields:

Manifold symbol | symbol (name) of manifold entered in the data table |
No. of circ. | number of circuits originating in the manifold (not the number of outlets, which may be higher, as there may be additional outlets for connecting radiators) |
Total pipe len. | total length of pipes of all circuits of the manifold | [m]
tr/qr | mean return temperature for the manifold, based on flow rates and return temperatures in individual HZ’s of the manifold | [0C]
Flow rate | total flow rate of heating medium across the manifold | [kg/h]
Avail. press. | defined (calculated or specified by user) available pressure to be provided for the manifold. The manifold is balanced for this pressure | [Pa]
Req. avail. press. | required minimum available pressure for the manifold, determined during calculations. When balancing is done for a user-specified pressure, this field specifies the minimum pressure that can be used for the manifold | [Pa]

The number of heating zones heated by pipe feeds assigned to the source may additionally be displayed under the table.
