Never mind, is a hot water recirculating pump worth it?

The traditional ones usually consume more electricity than an under sink hot water recirculating pump. The answer here is that they won't save you money if the utility bill is of concern, but they are still worth it as they are low-end electricity consumers overall.

Just, how do I choose a circulation pump? 1 GPM = 10,000 BTU/hr, meaning that for every 10,000 BTU's of heat load the circulator must output a 1 gallon per minute flow. Assuming that system calls for 100,000 BTU/hr, a circulator pump should have a minimum 10 Gallons Per Minute flow rate at a given pressure drop.
