In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
direct vent oil-fired hot water boilers
I had the same issues in my home when we switched from a mixture of propane hot air units, wood stove and disconnected electric baseboards to forced hot water. We found a contractor (here on the board!!) who explained the various options and we ended up with a Buderus boiler with direct vent. I would have preferred a chimney but for a variety of reasons it just wouldn't fit.
Been 3 years now with no exterior staining visible. The system runs well and we are currently burning about 750 gallons of oil per year. Very satisfied.
