What are the key questions to ask for installing a water heater?

Type here...We are replacing our old 40 gallon gas water heater with a new one. It is still working, but it is about 15 years old. We are contacting 3 or 4 plumbers for prices and want to ask the appropriate questions to compare and get the work done that we need done.

Make sure they get a permit if required. Ask if they will haul away the old. Type of new heater installed and tank warrantee. What kind of parts will the price include, you should have an expansion tank installed and make sure they counter balance the pressure to match the static pressure in the home. Should also include new dielectic unions, do not reuse the old ones. See what the rate for extras is in case they need to do additional work. Check references if possible.

Talk to your local building inspector. HW heater installations have become more complex in recent years, particularly with regard to venting them. You might be able to bring the list of plumbers you have to the building inspector, and while they can't reccommend anyone (conflict of interest), you will be able to tell by the way they talk about the different plumbers which ones they favor and which one have been a problem. Also - if you buy at Sears or another franchise, they may have their own people. While the installation are more complex these days, it's still a pretty basic job.
