Brockway Elements is a 100% wool 3-ply with a published TOG value of 1.8. Elements is a 100% wool 3-ply carpet rated 1.8 TOG. Its substantial pile puts it near the combined limit, so it demands the lowest-TOG underlay over underfloor heating.
Using the UHMA rule, in-situ resistance is carpet plus underlay minus 1. To keep Brockway Elements under the 2.5 TOG limit the underlay must be no more than 1.7 TOG.
TOG measures thermal resistance, so a low number means heat passes through easily. For a floor covering over underfloor heating that is what you want. A comfort underlay chosen for warmth underfoot does the opposite job and is the usual reason a heated floor underperforms after a carpet goes down.
