Heated Whisper Loop
(Published on 26. January 2024, 20:29 by yttrio)
This puzzle is the start of a loop series that uses thermometer clues similar to the arrow clues used in Pointed Whisper Loop.
Rules:
Normal Sudoku rules apply: Place the digits 1 to 9 in every row, column, and 3x3 box.
Along thermometers, digits must strictly increase from the bulb to the tip.
Draw a one-cell-wide loop of orthogonally connected cells. The loop may not touch itself, not even diagonally.
-- All thermometer bulbs must be on the loop.
-- The digit in a thermometer bulb gives the total number of loop cells in the 3x3 Sudoku box containing that bulb.
-- The loop acts as a German Whispers line (i.e., adjacent digits on the loop must have a difference of at least 5).
6x6 Example:
The image below shows a sample 6x6 puzzle and solution with the same rule set.
Note: For 6x6 Sudoku, adjacent digits on a German Whispers line must have a difference of at least 3 (instead of the usual 5)
Play the example 6x6 in f-puzzles.
Play the example 6x6 in SudokuPad.
Solution code: Row 9

Great puzzle! Thanks!
For someone a bit experienced with these kinds of constraints it‘s probably 2/5 stars difficulty.
