My kitchen is fairly far from my water heater, which is very close to every other hot water tap in my house. So when washing dishes I often have to run the tap to get hot water in the kitchen. In summer I run this water into my watering can for my garden. In winter I collect it in a jug and pour it into my clothes washer.
Same. Water heater is on the opposite side of the house from the kitchen sink. I have to run the sink for several minutes just to run the dishwasher, which is annoying as hell. I hate how much water have to waste just for the dishwasher to get hot enough to clean effectively.
You can fix the issue by installing a pump on your water heater, but that's a project that I'm saving for when I need a new one in a few years.
