I just purchased an EKO 25 as my main source of heat and hw. I currently have an oil boiler that I would like to keep as back up. A 500 gallon storage tank is my next purchase but I don't have the money for that this year. I would like to install in my basement about 20 feet from the oil boiler. Does anyone on here have a similar setup that is willing to share a diagram of the installation? I would love to install this myself and I know there are a lot of people on here that are wood boiler wizards!! thanks for any help!
