Brockway Heathcote is a 100% wool with a published TOG value of 1.51. Heathcote is a 100% wool carpet rated 1.51 TOG, the deeper-pile sibling of Heathcote Weave, needing a low-TOG underlay to work over underfloor heating.

Using the UHMA rule, in-situ resistance is carpet plus underlay minus 1. To keep Brockway Heathcote under the 2.5 TOG limit the underlay must be no more than 1.99 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.
