When I turn on my heater it make a loud banging sound on the pipes, I have repaired the heater 2 times. At first they emptied the tank and adjusted the pressure, then the second time they installed a pressure regulator (not sure if correct name?), and the third time they said there's a leak causing the water to boil and causing the banging sound, they suggested a new boiler. Any suggestions of what could possibly be the problem, or should I just change the whole heating system.

Dearly Beloved... We are gathered here today to talk about your plumbing problem. :)
You didn't state what type of heating system you have installed in your home but I experienced banging pipes before and there was air in the line that needed to be purged out. Quit simple and quiet!
What type of system you have would be helpful.
