i installed a eko 60 and 500 gal storage three years ago, i never let the fire go out as we are here all day and its easier just to keep it goin. anyway i have a work shop that is 52 X 60 with 18 foot sidewalls and has 7 500 foot 5/8 loops in the floor. we did heat it with fuel oil then switched it to waste oil, but that is a pain. thinking of runing lines from my eko out to the shop and installing 500 gal of storage and use that to help heat the shop. not sure if i have enough heat or if i should just install a 2nd wood boiler out in the shop. any help would be welcome
