Many of the HR monitors do a pretty good job. But, I assume you understand that any HR based measure of metabolic expenditure cannot account for the anaerobic expenditure of energy substrates.

Using known Max HR, and estimated relationships between Max HR, body composition and anaerobic thresholds, weight, gender and age is about as close as anyone can get. HR monitors can be very accurate if you exercise at a steady rate AND at intensities below anaerobic threshold.

As a side note, none of the "calorie estimators" have the capacity to account for the contributions of glycogen stores to total caloric expenditures. There is simply no way to do it.
