I need an opinion on a Tarm 402 boiler. I'm trying to decide whether to buy a refurbished Tarm 402 or go with a forced air furnace. I do not have a basement so whatever I end up with will have to go outside in a building. I have a forced air propane furnace that I can't afford to feed (stupid thing is broken anyway) so if I go with the boiler, I'd have to use a water to air HX. I'm thinking the boiler would be a better long term solution since I could change it out for a gasser later. I am on a very tight budget and a gasifier is totally out of the question right now. I have enough to buy the Tarm...or I could spring for a Fire Chief or Yukon Big Jack. I'm not crazy about the idea of punching holes through my foundation for air ducts. I realize that the boiler install would be more expensive since I'd have to buy the HX, circulation pumps, build a larger building, and come up with some tanks for the storage system. On the other hand, it would make all the DHW we would ever need (reducing my monthly donations to the power co), and it would make it easy to add some radiant floor heat later if I chose to. I guess I'm a little concerned about buying an old boiler. It has been cleaned, pressure tested to 50 psi, and had all gaskets replaced. Any suggestions?
