Does anyone else not use a heat exchanger and have their boiler plumbed directly to there indoor furnace? I own a Central E- classic and have plumbed mine this way. I have forced hot water baseboard, heating appx. 3200 sq. ft. house.Central boiler does list this as an option in their install guide. It seems like everyone is using heat exchangers. Perhaps most people have forced hot air systems. Just curious if anyone else is doing this, and if not , why spend hundreds of extra dollars on heat exchangers.
