Are hot knees a symptom of chondromalacia?

My kneecaps always get red and hot, especially at night - what could be causing this ?

Inflammation of the joint caused by chronic overuse? It won’t be chondromalacia per se as that’s simply the term for cartilage softening, a symptom of whatever is causing the problem.
Have you tried resting properly (for several weeks minimum) as suggested in your other thread?
In the meantime you could see if icing your knees for 15-20 minutes several time a day helps (with an ice pack wrapped in a towel to prevent ice burns).
You need to reduce inflammation to a minimum as it will in time lead to potentially irreversible damage to the structures in the joint including the articular cartilage (which is what chondromalacia patella is)

Came off bike onto concrete 9/9/09 (lat meniscus, lat condyle defect)
LK scopes 8/2/10 & 16/12/10
RK scope 5/2/15 (menisectomy, Hoffa’s fat pad trim)
LK scope 10.1.19 medial meniscectomy, trochlea MFX
LK scope 19.4.21 MFX to both condyles & trochlea, patella cartilage shaved, viscoseal, depo-medrone

Same here, diagnosed with patellofemoral arthritis. But the inflammation in your case can be caused by other issues as well of course, such as chronic overuse (as mentioned by Vickster).
RK sharp pain while running, diagnosis chondromalacia patellae 6/09
RK arthroscopic chondroplasty 9/09
RK rehab, recovery, 90% normal, started running again -> back to square one 5/15
RK diagnosis patellofemoral arthritis + LK diagnosis chondromalacia patellae 8/15 -> conservative treatment

How do you know the difference between chronic overuse and arthritis?

You need a scan such as X-ray or MRI to assess the state of the articular cartilage. Damage to that is what defines osteoarthritis, or wear and tear arthritis.
This primer explains about osteoarthritis

There are other types too like rheumatoid but presumably you’re not thinking of that?

This tells you about the patella/kneecap specifically
