Brockway Heathcote Weave is a 100% wool flat weave with a published TOG value of 1.29. Heathcote Weave is a 100% wool flat-weave rated 1.29 TOG. The flatter structure conducts heat more readily than a deep pile, keeping the pair in range with a low-TOG underlay.
Using the UHMA rule, in-situ resistance is carpet plus underlay minus 1. To keep Brockway Heathcote Weave under the 2.5 TOG limit the underlay must be no more than 2.21 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.
