How do you Purge ?

purging

There is no simple explanation on purging because of the variations of near boiler piping. If you're a homeowner, I'd recommend calling a company that specializes in hot water heat .Plus its always good to have your systems serviced to prevent problems down the road.  A properly installed system should not require annual purging.  If you try it yourself there can be problems that could present a dangerous situation such as dry firing. Good luck!
