I have a 22 ft. run from my hot water heater to my kitchen.I use almost 2 gal of water before the water starts to get hot.I try insulating the water line that did not help. Is there something I can do .Thank You.Bob

Bob, you can use a recirculating pump but then you heat more water and have to pay for the electricity for the pump. About the only thing to do is add more insulation.
