The circulation loop would be the hot line to the faucet then back through a new line to the cold intake of the heater. Insulated this loop would be an extension of the tank and only feed cold into the tank till the loop has hot. I understand this would cause the heater to run a little more but don't believe it would be all that noticeable.
