I got a gas fired steam boiler and when we purchased the house the last owner told us to change the water in the boiler once per year.
but one of my friend said with steam i should just add water whenever the water is below 30% on the sight glass mark but no need to change out the old water. But if that is true why is there a drain valve on the boiler than?
so should I change out the old water in the boiler? If so how often?
thanks.
