We are heating our house with a Riteway wood/oil boiler manufactured in 1979. This is our 6th year in our house but the first year that we have burnt wood in the boiler. My wife was afraid that I'd burn down our house. At the start of the heating season, I turned off the oil valve leading into the furnace and fired up a wood fire. It is great to have heat to our hot water baseboard radiators throughout the house but the boiler is terribly inefficient. It takes nearly 30 minutes with a roaring fire to heat the boiler temp. to 140 to kick on the hot water circulation. There also is no automatic temperature control for the wood fire. The air intake must be changed based on the temperature and pressure of the boiler which doesn't work well during the night. The guy who had the boiler installed said that once we burn wood, we will need to clean or replace the oil valve because it becomes dirty. We want to replace the boiler with a more efficient boiler that burns both wood and oil. Should I look for a combo boiler or buy two separate boilers? Our current furnace/boiler only has one flue with the wood and oil venting through the same pipe. I found this forum while searching for info on the Benjamin CC500. Thanks for the helpful information.
