I purchased a Synergy Boiler model XL100 in January. This was the first stove I ever purchased. I opted to get a new one as I don't have good experience with used units. Their website says that the XL100 can heat up to 10,000 square feet. I have a huge warehouse and got sick and tired of paying ridiculous fees to keep it heated. I thought I might need 2 to do the job, my warehouse is about 13,000 square feet and it heats it easily. I don't need it 70 degrees, but I have to keep up around 50 to prevent things from freezing. Anyway, either I got a great model, or they somehow gave me a bigger model than I paid for. Has anyone else purchased the XL100? Just wondering if you're getting the same results.
