We are currently getting bids to replace our oil boiler which is original to the house, 28 years old. There is an existing wood furnace tied into the system with a circulator that we want to maintain tied into the new system. With the price of oil, we bought 3 cords of wood for the first time ever, and are trying to use the wood furnace to lower our oil consumption (we used 1400 gallons last year.) Our home is 3400 sq. ft, we have programmable thermostats installed, and heat to only 66 degrees.
We are leaning toward the Buderus G215 ($5100) with Logimatic ($950 option), but the latest tech to come to our house for quote said he didn't think the Logimatic would work with the wood furnace. There are basically no thermal controls on the wood furnace. We just stoke it up and off it goes. My husband starts a fire when we gets home from work, stokes it up before we go to bed, and the oil heat kicks in when the fire runs out. Would we benefit from the Logimatic (or any other Outdoor Reset System), or would we just be wasting our money?
Also, our latest quote came with an interesting alternative. They have a Weil-McLain WGO-4 that they just took out of a new house that was converted to gas, and they are offering us that system at a reduced price. I'm still waiting for the quote so I don't have the $$ amount yet, but is it ever a good idea to buy a used system? They did say that they would give us a one year warranty.
We looked at the System 2000 which they estimated would cost us approx. $7K -$8K (we don't need the water heater), but that was out of our price range. Are we being pound wise and penny foolish?
Thanks in advance!
