My material library

I can't find the material I need, what can I do?

There are two options here: 

  1. If you know the building fabric composition but not the U-value, you can click on the [+] Custom material button and select Build Layers. You can then add each layer of building material from the drop down menu and its associated thickness (mm). The software is then able to calculate the corresponding U-value of the building fabric. 

  2. If you already know the thickness of the material and its associated U-value then you can input this directly by clicking on [+] Custom material in the material selection section and clicking Enter U Value. This will allow you to type in a custom name, U-value (W/m2) and thickness (mm) for the entire building fabric. 

For more information on this topic, see our guide on Managing Your Material Library.

How do you see the dimensions of a room & manually change them?

Clicking on the corner point of any room will display the adjacent dimensions. By clicking on the dimensions themselves you can edit the values by typing in the text box shown.

For more help on this topic, see our guide on Creating Rooms.

Plans task

How do the pink handles function?

The draggable pink handles are used for adjusting the size and shape of rooms. Initially they are set in the ‘locked’ function which allows you to drag that particular point, altering the size of the room while keeping the shape uniform. This setting can be changed by clicking on a point and selecting the alternative ‘unlock’ function which enables you to alter the angle at that point and thus create custom shapes.

For more help on this topic, see our guide on Creating Rooms.

Plans task

How do the blue handles function?

The blue handles allow you to split edges to add more corners. Simply drag and drop the blue handle to add a corner. If you just want to split a wall into different sections without adding a new corner, you can drag and drop the blue handle in line with the existing wall. This can be used to  add complex rooms to your floor plan, for example L-shaped rooms

For more help on this topic, see our guide on Creating Rooms.

Plans task

How can I create L-shaped rooms easily?

Moving the blue dots located on each wall will create new vertices. By dragging one of the blue dots along the boundary you can effectively split that wall in two segments while keeping it straight. Select the segment you need to extend outwards and click on the rectangular handle. A pop-up will appear allowing you to change to an oval-shaped handle. This enables you to pull out that portion of the wall to create an L-shaped room.

For more help on this topic, see our guide on Creating Rooms.

Plans task

Can I do vaulted ceilings?

Vaulted ceilings can be added by segmenting the roof into as many different slopes as are required. This is done by dragging multiple ceiling regions onto the design and fitting them accordingly. You can then set the associated height at the corners of each segment by clicking on them, selecting the up/down arrow and inputting the appropriate values (you must click the tick beside the text box to confirm). An arrow should then be displayed, this indicates the downwards slope direction of the ceiling.

For more help on this topic, see our guide on Vaulted Ceilings and Dormers.

Plans task

How do I add dormers?

Dormers can be added to any vaulted ceilings. For how to add vaulted ceilings see Can I do vaulted ceilings?

Too add a dormer simply drag and drop the Gable Dormer or Shed Dormer function onto where it is required. The dormer will automatically orientate itself with the slope of the roof. The specific dimensions can then be set, as well as the roof, wall, and window materials.

Plans task

Do I need to add stairs?

The nature of the calculations carried out by Heatpunk mean that you do not need to account for stairs. The landing and hallway can be considered separately and therefore should be added as separate rooms on separate floors. 

Plans task

What do I do if only a section of the wall is a parting wall?

If only a section of the wall is a parting wall, for instance, if there is a garage behind half the wall but not the other half, you can split the wall using the blue handles. Simply drag and drop the blue handle to the point where the wall needs to be split. You can then select whether the other side of this wall is a heated or unheated space. In the example, you would select one half of the wall as unheated space and the other as outside

Plans task

Do I need to model unheated spaces?

In general, you do not need to model unheated spaces. All rooms included will be added to the total heat loss calculation and therefore the heat pump will be sized against this. Therefore, including unheated spaces could lead to oversizing the heat pump. Its therefore, better to exclude unheated spaces in most cases, for example garages and conservatories. Instead, you should specify the parting wall between the heated and unheated space. 

However, some unheated spaces should be included for practicality, for example internal store rooms. Rather than leaving a gap in the floor plan, rooms like this should be included. In line with MCS, Heatpunk includes a room type for this scenario (Store).

How are radiator outputs calculated?

Heatpunk calculates actual radiator outputs with the below formula. This allows us to easily consider differences in flow, return and room temperatures.

image.png

where

P = heat emission from radiator (W, J/s)

P50 = heat emission from radiator with temperature difference 50 oC between the radiator and room(W)

ti = water temperature inlet (oC)

tr = water temperature outlet (oC)

ta = surrounding air temperature (oC)

n = n coefficient

The other way you can calculate radiator outputs is by calculating the correction factor based on temperature differences and the specific radiator being used. This can then be multiplied by the power output given on the datasheet to give the radiator output. To calculate the correction factor you should use the below formula. 

image.png

where

 n = n-coefficient (from radiator datasheet)

trad = mean radiator temperature

troom = room temperature

dT = delta temperature used on the datasheet for the relevant radiator (this is usually 50oC)

In the room breakdown of Heatpunk it should give you the total heat loss of the room and then radiator outputs will be calculated based on the flow temp you have used. The rads built into the software are based on Stelrad classic compact, so if you are using heat emitters where the outputs differ significantly you should add them in as a custom radiator to ensure the outputs are calculated correctly. 

Heat pump task

How do you select underfloor heating?

Underfloor heating can only be implemented in the Heat Pump design stage. To do this, select Add Heat Emitter and choose Underfloor which will prompt you to input the floor area covered by the underfloor heating elements and their outputs in W/m2.

How is the outdoor design temperature (ODT) set and can I change it?

The outdoor design temperature (ODT) for your project will be automatically set using the 99th percentile temperature for the relevant project location from CIBSE guide A. Using the 99th percentile temperature means the temperature will only fall below the ODT for 1% of the year. You may choose to use the 99.6th percentile in which case no additional uplift is needed for intermittent heating or exposed locations (see MIS 3005-d for details. Using the project's location, Heatpunk will also automatically remove 0.3°C from the ODT for every 50 m above sea level.

To change the ODT used for your project:

Note: An additional 0.3°C will need to be removed for every 50 m above sea level, with altitude given in the input section of the technical report & customer proposal.
