Is it hot yet? Is it hot yet? Is it hot yet? We've all used faucets and showers that take forever to get warm. All is not hopeless. There are projects you can DIY to get your water flowing hot quick. The homemakers at Q&A network Stack Exchange provide some tips.

Our water heater (gas) is located in the garage. It is 25 to 30 feet away from the closest faucet, which I'm guessing is the main reason it takes so long?a minute or longer?to get hot water flowing into my house.
What can I do to reduce the time it takes to get hot water flowing?
JD Long Answers:
The best way to speed up hot water to the tap is through the use of a booster heater, also known as a "point of use" hot water heater. This is a small (~4 gallon) hot water heater installed very near the sink. If you need a lot of hot water and you want it to start fast you can install the hot water line as the supply for the point of use heater. That way you will have 4 gallons for immediate use and if you use that up you will be drawing hot water from your main hot water heater. If you don't need more than 4 gallons of hot water at the sink you can just use cold water as the supply. Here's an example (pictured at right) of a point of use water heater for sale at Amazon.com.

Install a hot water recirculating pump. Older pumps required that the house be plumbed with a return loop to support circulation, but newer designs can be retrofitted if a house wasn't plumbed that way.
More info here.
Money saving tip: put the pump on a timer and have it come on only when you typically use hot water at that location. Or use an X-10 switched outlet (or something similar) to allow remote manual switching combined with timed events.

Insulate the hot water pipes from the hot water heater to the faucet. Hopefully you have access to them in your crawl space.

There really isn't a perfect solution to slow-flowing water, other than carefully planning your home so that the water heater is as close to the faucets as possible.
As stated by Josh, one solution is water recirculation. But depending on usage scenarios, water recirculation can waste a lot of energy. "Sense" technology that enables recirculation when needed can improve efficiency. And installing a system that uses the "cold" water circuit as a return line can make installation relatively easy.
If all else has failed, you can try quickly opening and closing the hot water?forcing the system to kick in. Wait a minute or so, and when you open again, you'll have hot water (and you will have saved a minute of running water).
Another solution is the instant water heater, like this one produced by Clage. It works by heating right next to the faucets. On-demand water heaters are quite efficient for usual "short burst" operation.
