I just have never used or really liked the torpedo style diesel fired heaters, as I have been in other shops/garages as they usually gassed me out/ or gave me a headache, but maybe the newest models are much better. I do know a few guys that used them often in their garage, and the one guy (his son told me personally) his dad passed away from a brain aneurism, and his son thought that breathing all those fumes for many years may have contributed to his death, but who knows for sure. I do know his shop had an awful film on just about everything from using that heater. Anyways... my brother and I have a model CL6048 Classic Central Wood Boiler and we have it plumbed to my house, and have heater plenums in all three wings of the shops, and all each have thermostats on them for heat control. Our main shop is heated 24/7, @60-62 degrees because it has a bathroom with stool/ and sink, with running water, which comes in handy. It was an expensive project, installing the stove and all associated components, digging all the underground water lines with an mini backhoe, piping all fittings w/pex tubing to the heater plenums and so on. We have about 12-13K putting it all together, the boiler is warranted for 25yrs, and I'm 50 yrs old and my bro is 55yrs old, we hope it lasts for the rest of our lives, after that time, someone else's worries! My brother and sister-in-law have an apartment out in the back southwestern wing of the parts storeroom building
in which they live their with the cats and one dog. The building sizes are, main building 28x60 and sistered next building is 28x60x12ft high and an attached rear lean-to is 20x70 an a front lean-to is 32x38 and another smaller lean-to off of the 28x60 building, which is 14x24. We have our blood, sweat, and tears invested in this place, but we enjoy/love this place! You can never have enough room, and everything is full. It is a lot of work cutting wood, but it is a great physical workout, but it is nice getting out in the great wide open woods!
