We bought this old farm house 2 years ago with a now 38 year old HS Tarm OT35 combination wood and oil boiler. Previous owners used mainly wood since boiler was new but we’ve using oil since we’re not home much. Average oil consumed past 2 years is 590 gallons. I know the old steel and cast iron fittings aren’t going to last forever so wanted input into what to replace with and how to find reputable dealers in our zip code area 12020. Currently leaning towards a new oil or pellet system. I’m thinking with a storage tank the system won’t need to be as large as our current system. Anyone using Evoworld, Froling P4, Effecta Komplete III, EcoBoiler, or WoodMaster on this site?
