Losing water

Nedwilly

During heating season, we constantly have to refill the water in our gas steam heat system. On the coldest days, it's at least twice per day. The safety shut-off kicks in usually during the night. We have replaced 90% of the valves on the radiators and there is no evidence of that much steam from any others. Any thoughts?

Check for white smoke when it fires.

I would check for a hole in the boiler. You can do this by filling the boiler with it turned off until the water is coming up the riser. Check in the peep door with a flash light. The prescribed test is bad if it is a finished basement and you do not proceed with caution and a good wet dry vac,

Is your condensate

return line a dry or wet return? If it is a wet return is it buried in the floor? If so it could be leaking.



Are there any steam leaks anywhere on the piping system.
