Does anyone have a Tarm boiler Model Solo Plus 40 without storage tanks. I was wondering how long of a burn time you get during the winter months? Also wondering how long people with Solo Plus get out of a burn with the pressurized 440 gallon storage tanks. Im trying to figure out which way to go, its another 5000 for the storage tanks. Anyone with information on the newer Solo Plus boilers would be great. Can't always believe the ratings from the boiler company. I live in Central NH and have a 3000 sq house, it is well insulated.
