Getting started with STEP® Design Planner


STEP® Design Planner gives you the option to request a quote for a single or several rooms in your house. To ensure we can provide you with a quote that reflects your actual heating needs, expected comfort level and a competitive price you should make some preparations before you create your design:

Measure the room(s) size (width, length etc.)

Identify floor areas where you have fixtures where heating is not required or possible (toilets, bathtub, shower, closet, sink, cabinets, drain etc.).

While you create the design you can always save your project and come back later to finish your design.


The STEP® Design Planner is currently released as beta version. If you experience any problems during usage, please give us a short feedback to help us improve the tool.
