Hello, to anyone that may need parts or be interested in a HS Tarm 502 multi-fuel boiler; I am removing my boiler from service (after 37 years!) and was hoping to connect with any other Tarm owners (or indoor boiler enthusiast) who may want parts or the entire boiler. I'm removing it in the next few weeks, and would love to see parts or the entire boiler find a new home. The total unit (dry) weighs around 900 lbs. It will fit through a typical man door easily. Has a Beckett oil burner model AFG. The only issue is when burning wood there is no automated control of the air intake. The dampener is manually controlled (auto control requires a part that seems not to exist). I have the original boiler manual from nearly 40 years ago, and various other original documents. I live in Northern Ohio. If any of this is of interest to you, or you have questions, feel free to contact me. Pictures available. Make an offer!
