With this cold snap I'm getting my first experience with continuous burning. Up to now with milder temps, I've been typically letting the fire burn down after the morning light and load, and then getting things going again either in the evening or next morning. Therefore buildup of coals was never an issue. After the continuous burn yesterday and last night I had a lot of coals built up. So today's strategy was to reload only 2-3 splits at a time, and before putting them in, move the coals to the front, and run with more air and higher temps. It's worked great, the coal pile is back to normal, and I'll be ready for a full load tonight. Will be interesting to see if my stove will keep the house above boiler thermostat set temp (65F) with tonight's wind and forecast low of -25F. Right now -10 outside and +73 inside.
