Description
The QH Grid underfloor heating system from Quality Heating has been developed for energy-efficient and fast warming. QH Grid also helps prevent cracks in tiled floors, making floor leveling unnecessary. Of course, this system also ensures easy installation.
This new underfloor heating system from Quality Heating has a thickness of only 5 mm (including the underfloor heating cable system). The Quality Heating QH Grid can be glued directly onto an existing tiled, concrete, screed or wooden floor, or placed on the ISO-64 insulation boards. Tiles can be applied directly onto the QH Grid system with tile adhesive. Of course, they can also be levelled.
If you follow the system build-up below, you will have a heat loss of only up to 4%!
- ISO-64 insulation boards 6, 10, 20 or 30 mm (optional)
- QH Grid 4.5 mm with cable system
- Tiles as floor finish or other floor covering combined with self-leveling compound
Calculate total area
Choose the desired power/area and thermostat type in the selection table above next to the photo. The price will automatically adjust and become visible. Example: you have a bathroom of 3.8 m². Total required is 3.5 m² of QH Grid system. You are then short by 0.3 m². You can order this separately here.
Our cable systems are made of Teflon and have a wattage of 18 W per meter.
The QH Grid system is very handy to use in difficult corners. You can click the cable into the system yourself so that no corner is too difficult. Note that the spacing between the cables must be at least 6 mm.
Now you may wonder what spacing you should use to make the best use of the cable. This differs per wattage. The higher the wattage, the closer the cable will be placed.
Below you will find a calculation to easily calculate the spacing.
You want to heat your 3 m² bathroom with a power of 160 Watt per m². This means a total power of 480 Watt. You should divide the heated area by the total wattage and multiply the result by 18 Watt per meter.
(3 m² ÷ 480 W) × 18 W/m = 0.113
The cable spacing in this case is then 11 cm. The cable spacing therefore determines the power per m².
80 W/m²: Supplemental heating for large rooms
120 W/m²: Primary heating for large rooms
160 W/m²: Poorly insulated room or smaller room
Are you going to level the system? Keep in mind that 5 mm of self-leveling compound is consumed in the QH Grid system to fill the grooves. This means that to reach the minimum height you should order 10 mm of self-leveling compound. Always ensure that a primer is applied to your subfloor to achieve good adhesion.
