Considering Intermittent Heating Operation

Shows step-by-step how to include interruptedly or rarely heated rooms in the heat load calculation and how to make settings for them.

Before you begin

You have parts of your project that are intermittently or rarely heated and you would like to include this circumstance in the heat load calculation.

Navigate to:

Note:

Depending on the selection under Additional heat-up capacityAdditional heat-up capacity, certain settings at the respective selected structure level can be adjusted differently from the project level.

Module overview ➤ Heat load ➤ Project level ➤ Heat load ➤ Intermittent heating operation

Procedure

  1. In the Additional heat-up capacity area, select the structure level at which you would like to manage intermittently or rarely heated rooms.
  2. In the Preset values area, activate the Use option, if you would like to enter the transmission loss coefficient and the net building volume manually.

    Otherwise, the values are determined from the heat load.

  3. Enter the target or minimum value that the heater controller should not fall below.
  4. Under Unheated interval, enter the period during which the relevant structural level is not heated.
  5. Enter the Reheating time in which the relevant structural level is to be heated up to standard temperature.
  6. Enter the Air exchange rate during the unheated period under Air exchange rate.
  7. Enter the air exchange rate for the heat-up phase under Air exchange rate Heating up.
  8. If necessary, enter an individual value for the temperature drop in the subsidence phase under Temperature drop.
  9. If necessary, enter an individual value under Reheat factor.

Results

The intermittent heating operation is set.
