Hello Everyone i need some help deciding what boiler to put in. Currenty i have an oil boiler with a coil for domestic water. It is about 22 years old, as old as the house. The house is a raised ranch, 1700 square feet on the top floor, and about 1000 finished square feet on the bottom floor. The boiler is on the bottom floor and heats both floors. Last winter we spent alot of money to heat the house, it is just me and my wife. We want to upgrade out boiler for this winter and need help deciding what to do. We have alot of wood stackedup ready to be burnt this winter, and have resourses to get more. Therefor we wanted to install a woild/oil combo. I have researched online and found the Atmos DC 32 SPL . it seems to be a nice wood oil combo. it is glassification. It is made out of steel and not cast iron, can someone tell me which is better? Does anyone have any reviews on this boiler? . One of the problems we have is that the boiler room is small, and there is only one flue, and enough room for one boiler (barely). WIth the set up of the house there is no where else to put in another boiler without having to make another flue/chimney. we do have room under our stairs to install a water tank for domestic hot water which would help during the summer. Attached is a picture of my current boiler set up and how i was thinking to install the Atmos DC 32 SPL . it is kind of tight though. So the options are: Atmos DC 32 SPL/ another wood oil combo that someone can recomnd/ or replace with just oil boiler (but if i go with this option, will it really be worth it? will it be that much more efficent then my current one?(i think it is about 86% effciency according to my hvac guy)) If anyone can share thier thoughts on our situation that would be great!
