We recently moved into a 100+ yr old, 2,000sq ft house which is need of a new boiler. I've just installed a pellet stove on the first floor and it's doing an adequate job of heating the house. We're able to keep the house 68-70 degrees without too much difficulty, but am going through the pellets pretty quickly (1 1/2 to 2 bags per day coldest days) plus I use the oil mornings/evenings and for domestic hot water. We have property with lots of trees ready (oak and maple) for harvest and plenty more from neighbors. I'm considering a wood/oil boiler for our baseboard and domestic water use. Right now, we have an old Peerless that sucks oil like an old Buick. So my question is, who has experience with this combo units, how well do they work, what are some of the headaches, etc? I'd have to keep a cord of wood in my basement, which is a dry area and there's concern about pests making a home indoors, is one of our questions. I'd like to have the option of burning wood in addition to the pellets, when needed, oil when absolutely needed (such as when we are away). I am looking at this brand of boiler to start> http://mainewoodfurnaces.com/CC500.shtml I can't install an outdoor boiler -- against local code. Thanks much!
