Just wanted to give kudos to hestia heating for a pretty interesting stove. bought one a few months back and it is in the basement of my 1880 square foot split level. with the recent weather we had and still are it kept my house at 72 deg all weekend from fri afternoon till mon. woke up to 15 below this morn and the house was the same temp all weekend. have to say its one of the best investments i have made.
