As is explained in both books your HR will always be lower going down hill. Going uphill you are having to lift your body against the pull of gravity so are doing more work then when going down hill. Similarly, you should not attempt to hold your HR to the same level on down hill as when going up hill when doing a simple aerobic base run. The downhill running has its own special value intuit it builds strength and muscular endurance as you resist the pull of gravity.
Yes, when it is hot your HR will drift higher. That is because in an attempt to maintain your body’s core temperature at its normal level, the capillaries in your skin dilate allowing more blood to flow to the skin and dump heat via evaporative cooling. This means there is less blood for the working muscles. To compensate the heart must increase its output so the HR goes up.
