Introduction to the Plan Task

Overview

[video/gif like 3D overview video and design modes video. Overview of sections (side bars, design area), sped up design. Wait til it's on staging. Purpose of this video is to show the flow of the task]

In the plan task, you model your surveyed plan and create design options based on the surveyed plan. In the design options you can then:

Complete sound assessment (UK only)
Complete ventilation calculations
Place where new radiators, the heat pump and cylinder will go on the plan and specify any relevant accessories
Specify other emitters, view room details and input any heat loss overrides.

Once you have completed the surveyed plan and the design option you wish to continue with, click Next in the bottom right.

Creating your surveyed plan

Read more about creating a floor plan and how to speed up creating your floor plan by uploading architectural plans with Heatpunk Pro.

When creating a floor plan, the first step is to select or create your material palette. You will then be prompted to input the default ceiling height and can then complete the surveyed plan.

When completing the plan, elements (rooms, radiators, windows, doors) can be dragged and dropped from the left-hand sidebar. On the Emitters tab, you can also access key details about the plan:

Click ⋯ three dots > 🡥 See room details to:
- View the annual demand, volume, area and heat loss for that room
- View the measurements for that floor
- Edit room temperature and ACH
- Add underfloor heating or other heat emitters
- Reset the room to the surveyed plan
Hover over the 🛈 info icon next to emitters to view:
- Total expected heat loss
- Total building floor area
- Total heat loss per floor area
- Total emitter output
- Total annual demand

All emitters added to this the Plan will be listed as Existing in the Emitters tab. To specify new emitter, add these to a design option.

Once you have completed your initial plan, click Finish Plan at the top.

Ventilation calculation

When you finish your plan, you will be prompted to complete the ventilation calculation.

For Heatpunk UK/IE, choose from:

Legacy MCS method / S.R.50-2021
Standard method / BS EN 12831-1:2017 using assumed air permeability
BS EN 12831-1:2017 using measured air permeability

Once completed, to edit ventilation calculations, in the top right corner click ⋯ three dots > Ventilation details.

Ventilation settings are consistent across plans, but the calculation is done per plan or option based on ACH and room temperature. To create an option with proposed MVHR, duplicate the project and input the proposed air permeability.

Completing design option plan

Once the sound check and ventilation calculations are completed, you can start speccing the heat pump, cylinders and any emitter upgrades. You can also specify the location of the new emitters, the heat pump, and the cylinder on the plan.

On the right hand sidebar, you can adjust the flow temperature using the slider. From the Sources and Emitters tab, you can view how this affects the heat pump and emitter outputs.

Changes made to the room temperature, ACH and emitters are specific to each design option. Changes will not apply across plans. Adjust the Plan if you would like changes to apply to each option. Read more about how design options work.

Heat sources

To add a heat pump, drag and drop a Pump from the left-hand sidebar. Once you have placed these on the floor plan, a menu will pop up to specify the model.

On the right-hand sidebar, from the Sources tab you can:

Edit outside design temperature

Set a custom outside design temperature (ODT). Note, changing this value does not affect the “outdoor low temperature” used in the MCS performance task.

Edit heat pump

Re-open the heat pump selector menu to change the heat pump.

More options

Click See more details to display the nominal capacity and ENA registration number. Click the bin icon to remove the heat pump from the design option.

Sound check (UK)

On the sources tab, where it says Sound check incomplete, click the ⋯ three dots and then the name of the heat pump(s) where the sound check hasn't been completed. These will display with a red cross next to them.

Hot water

Similarly, to add a hot water storage, drag and drop from Hot water on the left-hand sidebar. A menu will then appear to specify the model. On the right-hand sidebar you can do the following:

Edit hot water preferences

Adjust hot water storage and Legionella settings.

Edit hot water

Re-open the hot water storage menu to change the cylinder.

More options

Click See more details to display the DHW energy demand, legionella purge demand, weight, standing heat loss, coil size, immersion heater size. Click the bin icon to remove the hot water storage from the design option.

Emitters

Accessories

Once you have added a heat pump and hot water storage, you can add accessories to the project. When you click + Add Accessories from the accessories tab, compatible components will automatically be selected.
