Really cold nights in Maine drag it down when garage radiant comes on , then hot water , then bedrooms . been looking at ka -6 from keystoker wondering if its too big . I think my plumber rated the house heat loss arond 69,00 0 ?
house is 1500' garage (radiant) 900' basement (radiant ) 800' . New modular home heats well above 0 but man you can't lug enough wood when it's below 0 . My oil is 100,00 will keep up but sure runs alot . My concern is too much overboil if ka-6 is too big . I probably will only use for winter season
A KA-6 will idle for weeks at a time without "overboiling". If nothing calls for heat, it just runs enough to keep the fire alive...it isn't like a wood boiler that always has a bunch of wood smoldering. Based on your description, a K6 is as small of a boiler as I would consider... a K8 or EFM 520 might be a better bet.
