Radiators and Circuits

Document radiators and underfloor heating, then organize them into circuits.

Radiator capture screen

The radiator capture screen captures radiator details with dimensions, type, and valve information.

Capture a radiator

Navigate to a room
Locate the Heating section
Tap Add Radiator
The radiator capture screen opens
Select Circuit from configured circuits
Select Type:
- Horizontal
- Vertical
- Low level
Select Design:
- Unknown
- Standard panel
- Plan panel
- Sectional (modern)
- Sectional (cast iron)
- Tube column
- Narrow column
- Towel
Depending on design type, select additional details:
- Standard panel: Select Panel convector type (Type 11, Type 21, Type 22, Type 33)
- Sectional: Select Tubes per section
- Column: Select Column rows and Element spacing
Select Height (in millimeters)
Select Length (in millimeters)
For some types, select Depth
For sectional types, select Section length
Select Connecting pipe diameter (in millimeters)
Enter Distance to heating source (in meters)
Select valve Manufacturer and model
Mark Radiator is broken or Valve is broken if needed
Tap Save

The radiator is saved with complete details.

Radiator types and design types

Radiator type

The orientation of the radiator:

Horizontal - Standard horizontal radiator
Vertical - Vertical radiator
Low level - Low-height radiator

Design type

The construction style of the radiator:

Unknown - Type not identified
Standard panel - Modern flat panel radiators with optional convector fins
- Type 11, Type 21, Type 22, Type 33
Plan panel - Plan radiators
Sectional (modern) - Modern sectional radiators
Sectional (cast iron) - Traditional cast iron sectional radiators
Tube column - Tube column radiators
Narrow column - Narrow column radiators
Towel - Heated towel rails for bathrooms

Radiator dimensions

Dimensions are selected from predefined lists, not measured directly:

Height

Select from available heights in the dropdown
Measured in millimeters
Vertical dimension of the radiator body

Length

Select from available lengths in the dropdown
Measured in millimeters
Horizontal dimension (width) of the radiator

Depth

Available for some radiator types
Select from available depths in the dropdown
Measured in millimeters
Front to back dimension

Section length

Available for sectional radiators
Measured in millimeters
Length of each individual section

Valve information

The radiator capture screen includes valve details:

Valve manufacturer

Select from a catalog of valve manufacturers

Valve model

Select a specific valve model from the manufacturer’s catalog

Valve broken status

Mark if the valve is broken or malfunctioning

Note: The radiator capture screen does not include photo capture. Use the Notes feature to capture photos of radiators and valves.

Heating circuit configuration

Organize radiators and underfloor heating into heating circuits.

Create a heating circuit

Open your Project
Locate the Heating Distribution System section
Tap Edit Heating System
Set the Main distribution pipe diameter
Tap Add Circuit
Select Circuit type:
- 2-pipe heating circuit - For radiator systems
- Underfloor heating circuit - For underfloor heating systems
Enter Circuit Name (e.g., “Ground Floor Circuit”, “Bedroom Zone”)
Tap Save

The circuit is now available for assignment when capturing radiators and underfloor heating.

For underfloor heating circuits

Underfloor heating circuits can include:

Manifolds - Add manifolds to the circuit for grouping underfloor heating loops
RTL Boxes - Individual loops can specify RTL box information if no manifolds exist

Circuit organization

Organize circuits by:

Floor Level - Group heat emitters by floor
Usage Zone - Group by room function or area
System Type - Separate circuits for radiators vs underfloor heating

Assign radiator to circuit

Radiators are assigned to circuits during the capture process:

In the radiator capture screen
Select the Circuit dropdown
Choose from available Two-Pipe Circuits
Complete the rest of the radiator details
Tap Save

To change the circuit assignment later:

Edit the radiator
Change the Circuit selection
Tap Save

Underfloor heating

The app documents underfloor heating systems at the room level.

Capture underfloor heating loop

Navigate to a room
Locate the Heating section
Tap Add Underfloor Heating
The underfloor heating capture screen opens
Select Circuit from configured Underfloor Heating Circuits
If the circuit has manifolds:
- Select Manifold
- Enter Distance to manifold (in meters)
If the circuit has no manifolds:
- Select RTL box manufacturer
- Select RTL box model
- Enter Distance to heating source (in meters)
Enter Floor area (in square meters)
Select Floor material:
- Concrete
- Wood/Chipboard
- Tile
- Other
Select Screed thickness (in millimeters)
Select Pipe spacing (in centimeters)
Tap Save

Troubleshooting

Can’t capture radiator

Verify you’re in a room (not at project or story level)
Create at least one Two-Pipe Circuit first
Circuits must exist before capturing radiators

Dimensions not available

Height and Length must be selected from predefined lists
If your radiator size is not in the list, select the closest value
Dimensions are in millimeters only

Circuit not in assignment list

Create circuit in heating system configuration first
Ensure you created a Two-Pipe Circuit (not Underfloor Heating Circuit)
Save the circuit before capturing radiators
The circuit dropdown will be empty if no circuits exist

Can’t save radiator

Circuit must be selected
Height and Length must be selected
All required fields must have values
Check that all dropdown values are valid

Valve information not available

Valve manufacturer and model are optional
If your valve is not in the catalog, leave it blank
Valve information does not affect the ability to save

Underfloor heating circuit doesn’t show manifolds

Manifolds are optional on Underfloor Heating Circuits
If no manifolds exist, use RTL Box information instead
Add manifolds in the heating system configuration if needed
