Measuring for underfloor heating
Measuring for underfloor heating is easy and can be completed in as little as 10 minutes using a tape measure, notepad, and a pen.
Room Size
Calculate the area by multiplying the length and width of the room.
Area (m2) = Length (m) x Width (m)
Top tip: If the room is an odd shape, divide it into smaller sizes and add these together.
Unheated Area
Measure any unheated areas in the room and again calculate the size.
Unheated areas include fixed elements such as kitchen units/islands, fitted wardrobes & fireplaces.
Total Heated Area
Subtract the unheated area from the total area, giving the total heated area. This ensures you don’t overestimate your project and spend more on unneeded materials.
Total – Unheated = Heated Area
Other considerations
Are there different heated zones?
If there are multiple zones repeat this process for each area, each zone will need a separate thermostat. When measuring for underfloor heating, ensure to account for all zones.
Thermostats and controls.
Think about the number of thermostats required for the installation. Wet underfloor heating may require additional controls including actuators and a wiring centre. When measuring, take into account where controls will be placed. Contact us to find out exactly what you need.
Measure the depth available.
This will allow you to ensure the installation matches the desired finished floor level. Consider the height of the heating system, insulation, screed, intermediate layers, and the final floor covering. Ensuring the finished floor level matches your requirements is essential for a seamless installation when measuring for underfloor heating.
Next Steps
Measuring Electric Underfloor Heating
Measuring correctly for electric underfloor heating is crucial, as the heating wires can’t be cut or trimmed.
Measuring Water Underfloor Heating
When installing in a single zone, you can use our single-zone underfloor heating kits. If you want to estimate your underfloor heating materials, we have a blog that walks you through the steps.
Send us a floor plan!
You can send us your floor plan and we will provide a materials estimate for your project. We create our estimates based on your measurements. Find out what we need below.
Layout for an underfloor heating quote
VPS generate an underfloor heating quote from your project measurements. Technical CAD drawings in PDF format are preferred, but we can also work from images. If you do not have a technical drawing, a detailed sketch will also suffice.
Please include
You can sketch this on paper or on a computer. Ensure that the drawing is clear and easy to understand. Proper measuring ensures that your underfloor heating layout will be accurate and effective.
