The right heat.
The right radiator.

Size a single room, then find a Kartell Kompact radiator that fits the space and your heating system.

01

Tell us about the room

Internal measurements, in metres.

What is on the other side of each wall?

Walls A & C run along the length. B & D run along the width. Window and door areas below are deducted from external walls.

Adjust the calculation assumptions

Defaults are estimates. If you know the actual construction, enter its U-values. Heated adjoining rooms are assumed to be at the same temperature.

Heat loss = fabric area × U-value × temperature difference, plus ventilation (0.33 × air changes × room volume × temperature difference). Ground floors use the entered ground temperature; this is a simplified estimate.

02

Set the temperatures

Match the radiator to how the system will run.

03

Find the right fit

Maximum dimensions apply to each radiator.

Allow extra space for valves, pipework and the manufacturer’s installation clearances. Dimensions shown are radiator height × width. Body depth excludes brackets and wall clearance.

How to read your results

This is an indicative sizing aid. Check dimensions, construction, ventilation and actual system temperatures before ordering. It is not a full room-by-room design or MCS assessment. Radiator covers and restricted airflow can reduce output.

ΔT is the average radiator water temperature minus room temperature. Outputs use Kartell’s published ΔT50 watts and correction table, interpolated between listed factors. BTU/hr = watts × 3.412.

The three conflicting entries S308K, D524K and D904K are excluded pending clarification. Type 33 triples are included in the recommendations and can also be selected using the radiator-type filter.
