Hi.I'm tony from maine. I'm considering buying an eko 40 to heat my 1100 square foot ranch and my working garage. I'm planning on installing the boiler in my basement and piping heat underground to the garage to radiant in the slab. Is this stove up to the task? Is it really necessary to install a storage tank right from the start or can it wait a while until I can afford one? ill be lucky if I can buy the boiler & install parts before next winter so not having to install a tank would help.
