I've made a few thermo variants. All are standard thermo sudokus + an extra rule. Check out the others using the following link:

Thermo Variant Series puzzles

If you enjoy "Maximal Thermos" or would like more practice first, I invite you to look at the others with the same (or similar) constraint:

14. Maximal Thermos
19. Maximal Thermos 2
21. All Maximal Thermos are Given
23. Incomplete Maximal Thermos
26. Maximal Thermos 3: Stubs
31. All Maximal Thermos are Given 2
35. Maximal Thermos 4ever

Rules: Normal sudoku rules apply. Along thermometers, digits must increase from the bulb end.

Variant: The thermos in the grid are maximal thermos. This means two things:
(1) the digit in the bulb equals the length of the thermo
(2) the tip of the thermo cannot be extended by a king's move to a non-thermo cell to create a larger thermo.

For example, if r7c9 = 7 then r6c8, r8c8, and r8c9 cannot equal 8 or 9.
