The size of your room may be 5m x 4m (20sqm) but you may only need to heat 12sqm of the room.
Why is that? There are some general rules to follow when measuring the room for underfloor heating installation. The main rule is – if you cannot walk over it then do not heat beneath it. This rule applies to kitchen cabinets, kitchen islands, bathroom cabinets, toilets, bathtubs and other fixed units.
How to measure
It is important to review the room itself. Where the contents of the room are placed, which features or contents are movable or fixed.
Using a kitchen for example. Let’s say your room is 7sqm in size. You will not be placing heating underneath the kitchen cupboards so this will reduce the area you need to heat. So really, you are only potentially heating 2sqm of the room.
In the bathroom, measure around floor-mounted fixtures – bathroom floor cabinets and vanity, for example, unless the bath is free-standing and has an air gap beneath it, measure around it, too. Do the same with boxed pipework – deduct this area from the total. If you are looking at a Tiled Shower, you may decide to heat the inside of your shower, but perhaps cost for that separately and take in the costing factor of waterproofing and insulation as well.
