I'm new to the forum, but have been reading/learning as much as I can before installing a new system in our 1840's farmhouse. I'm currently making space in the attached ell for an EKO 60. The slabs in the ell and attached garage/shop will be radiant--not only to help my shallow foundation from heaving, but also to act as a heat-sink/thermal storage. I am planning to pump the hot water from the boiler into the cellar under the house--close to where the the heat will be used. I have been on the look-out for bulk milk tanks and used propane tanks for MONTHS! and have found very little. Part of the problem is that my cellar bulkhead access is very narrow. I have decided that 2 500 gal. propane tanks or even a 1000 will fit in best. But I can't find them. Does anyone in Maine--preferably between Belfast and Augusta--know where I can find used tanks?? I have tried several places, but am always told NO because of some mis-perceived liability...... I am at a loss and winter is coming on fast.... Any recommendations or help would be appreciated! Thanks.
