Draining boiler

At a home inspection, inspector said you have to take water off a boiler weekly during heating system. It is a newer boiler,2012, well mclein steam radiators. Never had a system like this and did know the accuracy. Is it necessary to purge system during heating season?

Are you sure this is a steam system and not a hot-water boiler? If it doesn't have a gauge glass to show water level, it must be a hot-water boiler. If it has a circulator pump, it must be a hot-water boiler.

A steam boiler is usually provided with piping for blowing down the boiler to remove sediment on a routine basis. A hot-water boiler will have a drain valve, but it should not be routinely drained except when necessary for maintenance of a component, such as a circulating pump.

Draining boiler

Thought I saw a glass gauge in back of boiler. Home inspector pointed to boiler valve on where to drain off water weekly. Just never heard this info before.

Before you do any draining...

Please go to the boiler and look at the data plate and tell us the make and model of the boiler.

If this IS a steam system, there is a bit of information you need to know.

If it's a steam boiler's gauge glass, it would be a cylindrical glass tube, maybe 12" long, mounted vertically. The diameter of the tube would be about 3/4". I wouldn't normally expect it to be located on the back of the boiler. A photo would help us. Also, show us a photo of the drain valve, with the surrounding piping, that the home inspector suggested you open.
