Summer's over, the garden is harvested and I began thinking about a new project. Then we had a cold snap and I decided to fire up my heating system, but my boiler wouldn't start due to low water level. Fearing the worse i crawled into the firebox with a flashlight, and observed a small stlagtite of calsified material hanging down from one of the tubes. "Perhaps it's just a pinhole", I silently prayed. The pressure washer quickly knocked down all the ash and slag, and I could do nothing as all my boiler fluid (50/50 water and propolene glycol) ran out and soaked into the ground. The first pic is in situ, at first I thought the damage was caused by fuel erosion but a look on the outside of the housing indicates a hot spot caused by too much insulation and the close proximity of the the liquid lines. Now I have a project: pull the water jacket out and make repairs, before it gets cold.
