One of the things that we have used to great success is to remove the sacrificial anode and insert a 1/2 inch pipe into the opening (remember to turn the cold water supply off first) and connect this to a wet/dry shop vac. Turn the vacuum on and keep going til the water is drained, you may then change the element. Make sure that the wattage is correct and remember that changing the boiler drain valve is easy, email for info. on how to do that.
