Introduction to the Plan Task v2

Overview

In the plan task, model your surveyed plan, with any existing emitters, and create design options based on the surveyed plan. In these design options, you can model emitter upgrades, place the heat pump and cylinder and specify any accessories.

Heat loss calculations are fully integrated into the plan process In the plan task you can also complete sound assessment (UK only) and ventilation calculations.

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

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.

To build your plan, drag and drop elements (rooms, radiators, windows, doors) from the left-hand sidebar. As you build the plan and add emitters, you can view the heat loss, total building floor area and W/m². For details on the heat loss for individual rooms, click 🡥 See room details on the right-hand sidebar on each room.

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

All emitters added to this the Surveyed plan will be listed as Existing in the Emitters tab. New emitters will be specified in a design option. Read more about emitters.

Once you have completed your initial plan, click Finish surveyed 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 directly onto 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.

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.

Sound check (UK)

The sound check status can be see on the right-hand side. Click the ⋯ three dots and then the name of the heat pump(s) where the sound check hasn't been completed.

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.

Read more about specifying hot water storage, including information on domestic hot water calculations.

Emitters

The Emitters tab largely works in the same way outlined above. They key difference is that from design options, you can model emitter upgrades:

To upgrade existing radiators, click on the radiator from the plan and click upgrade. Input the new radiator details and save.
To replace an existing radiator with UFH, delete the radiator from the floor plan and add underfloor heating by clicking the 🡥 icon on each room. Click Add underfloor heating and input the output and m².

You can also add room overrides, by clicking the exclamation icon and input the reason for the override.

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.
