<p class="MsoBodyText">The Floor Panel <font style="background-color: rgb(49, 106, 197);" color="#ffffff">Heating</font> System provides <font style="background-color: rgb(49, 106, 197);" color="#ffffff">heating</font> for one or more
zones by circulation of <font style="background-color: rgb(49, 106, 197);" color="#ffffff">heated</font> fluid through a network of pipes embedded in the
floor or ceiling. A single pump, rather than the primary-secondary pumping
arrangement shown in the schematic, is installed for single-zone systems. Space
temperature in each zone is controlled by varying the temperature of the fluid
circulating in that zone. Hourly head addition rate is determined for this
system exactly as for other types of systems. Pumping energy associated with
this system is accounted for by the PUMP attached to the CIRCULATION-LOOP. The
ratio of panel <font style="background-color: rgb(49, 106, 197);" color="#ffffff">heat</font>
losses to panel <font style="background-color: rgb(49, 106, 197);" color="#ffffff">heating</font> output must be estimated by you and entered; see
the keyword PANEL-<font style="background-color: rgb(49, 106, 197);" color="#ffffff">HEAT</font>-LOSS in the ZONE command). The program assumes that
this ratio of <font style="background-color: rgb(49, 106, 197);" color="#ffffff">heat</font>
loss to <font style="background-color: rgb(49, 106, 197);" color="#ffffff">heat</font> output
remains constant over the full range of panel output.</p>

<div>Hello,</div>
<div> </div>
<div>I have a project that uses solar thermal tubes to heat up water, which is used for radiant floor heating. During the peak hours, solar thermal is boosted by a boiler. Can anyone please expalin how I can model that? If it can be modelled, how do I control the loop in a way that the boilers kick in only when solar thermal cannot keep up? Thanks everyone.</div>
