How to measure for underfloor heating kits

More information on how to measure for your underfloor heating system.

Keeping your family warm in the winter has never been more important, and with so many options at your disposal, there’s one technique that is becoming more and more popular within houses of all shapes and sizes – and that’s electric underfloor heating.

Not only can installing electric underfloor heating help to promote a warmer living environment – it’s also incredibly cost effective when compared to other heating methods. Electric underfloor heating provides heat through the process of radiant heating. Under engineered wood, laminate flooring or tiles, electrical underfloor heating systems will help to distribute heat more evenly around your home, and combined with the various methods of insulation in your property electric underfloor heating is extremely economical.

Underfloor Heating Installation Considerations

Before undertaking any heating installation, it’s a good idea to properly calculate your underfloor heating requirements. It’s easy to measure from wall to wall and hope for the best when it comes to setting your heating up – but there are several elements to consider beforehand. If you’re keen to learn how to measure for underfloor heating then you’re on the right page.

There are several different types of underfloor heating that you can choose from – all of which serve the same purpose. If you know how to measure for an underfloor heating mat then you’ll appreciate that there are a few things that you’ll need to keep in mind before the installation process is able to begin.

If your chosen room has what are referred to as ‘permanent footprints’ (consider baths, sinks, kitchen islands, units and other permanent fittings), then you’ll want to take these into account – as explained in our step by step guide. Not all fittings will be temporarily movable, nor are they all suitable for underfloor heating – and that’s why it’s important to consider them when measuring your room.

Calculating Underfloor Heating Needs

The easiest way to ensure that the right measurements are taken, is to first calculate the entire square metre area of the room itself and then measure the permanent footprints. Next take the total floor area of the room and subtract the difference taken up by the permanent footprints. It’s unlikely that any two rooms will be the exact same size and shape – and this becomes even less likely when considering the permanent footprints that the room might possess.

Therefore, it’s not always possible to simply measure a room in order to apply heating mats under the entire surface – even if the room is currently empty and awaiting decoration. This is because of the tendency for specific items to be added to the room at a later date and these should be considered now, especially in the case of bathrooms and kitchens.

Once you’ve calculated the overall size and space within your room, you’ll want to make a few minor adjustments to ensure that your heating installation is able to proceed without a hitch. Knowing how to calculate underfloor heating requirements is one thing – and a commonly overlooked consideration is where the heating will be aligned as far as the edges of your room are concerned.

To arrive at the correct size of mat we recommend removing 10% from your calculated heating area – just to allow for proper fitting. Placing heated mats right up to the edge of a room is unnecessary. The figure obtained from this calculation should be rounded down to the next whole number or size.
