It should not take any longer than it always used to take, to heat the water after you have left it turned off for say a week - like if you went away from home for a holiday. If it does not heat the water you could check two things yourself: * is the Gas supply actually turned "On"? (It may have been left turned "Off".)
* has the water temperature thermostat been turned to a very low temperature or even to "Off"? If the Gas supply is definitely "On" and the thermostat setting is set to a normal temperature then something else inside the unit may not have been reset from "Off" to "On" by the technician who did the yearly maintenance.
The best advice anyone should give you is to call that maintenance technician back to fix the problem!
Many homeowners aren't aware that yearly maintenance should be performed on the hot water heater. The tank should be drained to allow all the sediment and dirt to run out, and then refilled. This is fairly simple to do and instructions should be found in the manual for your heater. If you no longer have the manual, one can usually be found on the heater brand's website. Before attempting any maintenance on your heater, make sure to turn off the power source. It's also important to wear thick rubber gloves to protect your hands from the steam and hot water.
