    Constant loss steamer

    There are a few postings here on that subject, so do a search.

    The problem to be overcome is the constant addition of fresh waste to the boiler which can introduce too much oxygen into the boiler hastening it's demise.--NBC

    Feed water

    Feed it through a small water heater, set at the highest temperature, and use a microbubble reabsorber in the feed line. That will take care of the air and the heater will give the sediment a place to settle, other than inside the boiler. Adds years to the boiler's life.

    WaterHeater, microbubble reabsorber?

    If this works to prevent the introduction of co2 into the system, why isn't it used with residential steam for make-up water?

    Why, indeed.

    The reason is...no reason.

    The REAL reason is that a residential boiler should not be using a lot of fresh water. And if water is added for maintenance, it should be boiled immediately. Whatever sediment accumulates over the years can be cleaned out.

    In this crab steamer, there is so much fresh water being used daily, that you there is no way to maintain it often enough to prevent a problem.

    You can use hot water for make-up water

    But don't run it through an automatic water feeder.

    (Actually, consult your local code. It might not allow this.)
