Howdy, I am a new member and this is my first post. I purchased a home with a Tarm MK II Solo Plus wood boiler with 690 gallons of thermal storage. In late fall/early winter I started the boiler to heat the house but let the fire burn out before going to bed. I try not to let my thermal storage get above 170 degrees. With the boiler not burning overnight, the water is still circulating but the temperature in my tank drops at least 10 degrees. It is cold in the house in the morning and the fire out by this time. My question is this: Now that it's really getting cold outside, how do I maintain my air temperature all night? Do I load the boiler with wood and turn down the draft fan so the fire burns (or smolders) all night? I thought that's what caused creosote. Should I strive to keep my boiler burning all the time or should I cycle it like I have been doing? Any advice would be appreciate.
