Why is my Floor not Reaching Target Temperature?
Reaching Target Temperature
Heat loss in the subfloor or the space below causes floors to heat up more slowly. A slower heating time takes longer to reach the target temperature. This is due to your heating system being installed over a concrete slab or an unheated space without insulation boards. Fortunately, Warmup insulation boards create a thermal break between your subfloor and heating system. As a result, the insulation provides a much faster ramp up time, preventing heat loss making your system more efficient.
It may take time if you are turning your system on for the first time. To fully warm, it may take up to three hours for your floor.
