I’m in the process or researching boilers. I’m thinking either the Tarm or EKO after ruling out the Greenwood. The boiler will be going in my basement where I would like to hook it up to storage. I have found two 500 gallon LP tanks that I can pick up reasonably. I also have a way to get the tanks into my basement even though a garage hook up is also possible. Is the weight a problem on my concrete slab? It looks like each tank full will be about 5370 lb. 500 gallons x 8.34lb per gallon + 1200 lb for the tank. The hook up will be through my gas boiler and using a super store for my domestic HW. I’ve seen different schematics on how to hook them up to LP tanks. Do I need to have welding done on the tanks or would I be able to use the fitting currently on the tanks. Any advice for a novice with no plumbing knowledge would be helpful. Also if anyone knows anyone in Northern Vermont that puts in these systems I’d be interested in talking to them about doing an install.
