Everything works well and works correctly, and I sleep very well at night and I am not using a lot of coal.

I found the steel compression tank flooded and I know now it was the coil. I shut off the water feed to the coil tonight and then drained the tank of excess water to correct the air to water volume ratio of 1/3 air 2/3 water.

Leon, please expound upon this. What is the reference to the "coil", and how did it cause your expansion tank to flood?

Hello and good morning Larry, Klook,
As the house was cold I new that there was problem. I checked the gauge glass and viola it was full to the upper gauge glass valve (its only supposed to have about 6 inches of water in it with 2 inches of unfilled gauge glass. In checking the gauge glass this morning the water level is still where I left it yesterday.
Last night I shut the tank valve off then I drained the excess water from the steel compression tank until I had only air venting from the tank I then shut the vent off. After I shut the vent off I then reopened the tank valve and the system moved more air from the steam chest and then the hot water started moving again through the 3/4" fin tube baseboard.
The water feed to the boiler is completely shut off and the only possible location that water could enter the boiler is through a pin hole in the domestic hot water coil.
I am not sure if the heavy wall thickness refrigerant grade copper is used to create the domestic hot water coil but I believe that is what they use.
I am unsure if another type of coil like the straight copper trombone coils used in the Axeman Anderson units is available for these boilers.
It is one more thing to fix this coming summer.

If you have a drain valve on the coil, it would be easy to check. Leave the house water to the coil turned off, attach a hose to the coil drain valve, open the coil drain valve.
After the coil is drained, leave the valve open for a few hours to see if any boiler water leaks out. If no boiler water leaks out, the coil is in good condition.

Hello Don,
Sadly, I have no drain valve on the coil. I will leave it shut off completely for now.

That is not a very old boiler to already have a leak.
Everyone's water has different properties, but yours is mighty terrible.

Hello McGiever,
I know, but I finally narrowed it down to the coil as the issue. I just have to plan on how to fix the plumbers screwed mess up the installation on that side and find out how much a plate cover for the coil port is going to cost versus just keeping the feed valve shut off.
I have water that has a little iron in it and a small amount of sulphur. I have a water softener and it runs on a total number of gallons used between cycles. The raw water from the well coming off the outside sill cock is fine.
I use a little Iron Out and water softener pellets with iron reduction chemical in the compacted salt pellet

Hey Leon, the coil from a KA-6 won't fit in the KAA-4-1 will it?

I am not sure if it will work.
