Once the heat loss calculation is complete, a properly sized heat pump can be selected to meet the heating needs of the property. 

    On this section, a range of heat pumps is shown taking into account the minimum heating power needed to meet the needs of the porperty (total heat loss).



Heating Capacity ≥ Total heat loss


    You can access your own predefined catalogue of HP, ordered by the following criteria.

  1. Brand name alphabetically;
  2. Cost;

  

    By default, you can observe heating power at reference conditions (A7W35) and the download of the HP datasheet is possible to check the parameters at specific conditions.


  After selecting the heat pump, one crucial step is the sound check level. For this analysis is required to indicate some details about the installation place, such as:

  • how many reflecting surfaces the heat pump will have around (within 1 meter);
  • distance to assessment position;
  • if there is any barrier between the heat pump and the assessment position.


    This validation must be done for every assessment position, in other words, for an external position 1m perpendicular to the center point of a door/window associated with a habitable rooms of a neighboring property.

  After selecting the Heat Pump, some design information must be carried out:

  • Flow temperature and Heat source DT (return temperature is calculated automatically). This will impact emitter sizing (Step 5), as well as performance estimates.
  • You can specify the heat transfer fluid, this will impact Mass Flow Rate KPI.
  • Main emitter type does not have impact in calculation as you will have the chance later to perform an emitter sizing per each room, but you will get an update visual of the emitter around flow and return temperature fields.
