Brockway Landmark Abbey is a 100% wool fine-level loop with a published TOG value of 1.3. Landmark Abbey is the fine-level loop texture of the Landmark range, 100% wool rated 1.3 TOG. The tight loop sits at the lower end of Brockway's wool range for a heated floor.

Using the UHMA rule, in-situ resistance is carpet plus underlay minus 1. To keep Brockway Landmark Abbey under the 2.5 TOG limit the underlay must be no more than 2.2 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.
