Hello All,
I purchased a ridgewood 7500 last october (2011) installed it my self, I installed 500 ft. of pex going to 3 buildings. total of 5000 sq. foot not including my hot water, which I ended up using a 20 plate. i used the pumps and pex that ridgewood recommended, I have to admit I was a bit skeptical about it all, i thought worse case i would have to eliminate 1 of the buildings if the furnace struggled. Considering we had above average temps here in michigan this year, the furnace produced as it should and i could not be more happier with my 3000.00 plus savings compared to a big name furnace. I have friends with woodmasters, heatmor and central owb's. I can say the natural draft was not an issue, but I'm pretty confident it will not burn green wood like the forced air models. I had no problem finding seasoned wood, so this was not an issue ( I did mix some green in with seasoned and still no issues). i can also add that each of my friends at one time or another every winter are changing a fan, there again not an issue for me. although I bought an extra solenoid, which is what works the draft door on the ridgewood., but did not need it this season. Certainly the warranty is a concern because if ridgewood go's out of business, the warranty is useless, i hope other people see how good the product is, buy from him, ridgewood will stay in business and everones warranty will be valid. Just wanted to put my infomation out there for all the people that were skeptical like myself.
