We have a Hyfire II and now have the Coal-trol operating our furnace fan automatically. We're getting good airflow. But, what's coming out of our vents is barely, slightly warm air. We've also been having an issue that started at the END of last heating season, where the night temp is dropping to 67 although Coal-trol is set at 69. Day temp setting is 70. I'm keeping a log, and each morning, temp is at 67, with FR at 0, or 12, or 36, etc., depending on outside temps. Min 4, Max 32 because of burning coal being dumped into ash pan. SFT 15. We tried it at 8, per Neil's suggestion, but then there was a lot of COLD air coming out of the vents.
After a lengthy conversation with Neil at Coal-trol place, we tried raising FR back to 40. Burning coals are now at grate's very edge, so I've just backed it down to 35. The Coal-trol temp read 68 this a.m., with FR of 16, and 5 minutes later, it read 69 with FR of 25, with outside temp of 31. However, our regular thermostat for our Carrier Furnace is right next to the Coal-trol, and it read a steady 67 regardless of what the Coal-trol read. Coal-trol now reads 69, with a FR 60. The setting for the DAY temp of 70 is at 6:15 a.m. and it is now 8:45. So at 6:18 a.m. Coal-trol read 69, and now at 8:45 a.m. it still reads 69. Carrier thermostat reads 68. I know that the coal stove doesn't provide instant temps the way our gas furnace does, but something just doesn't seem right.
Why is the air from the vents so cool? Seems we are losing heat somehow or somewhere. Even down in the basement, it used to be really warm in the stove area last year, and the whole basement was toasty. Now its not that warm, although granted, the stove hasn't been working hard yet. We used to have nice hot air coming up the basement stairs, too. I don't feel it the way I used to last year. Could be with the furnace fan on high now, (the setting for heat), it's pulling more heat from the stove, but then, where is the heat going? Certainly doesn't seem to be coming upstairs thru the vents. Even the 2nd fl. is not that warm.
Last year, before tieing the stove into our duct work and just heating by convection up from the basement, the house was an even 69-70, temps were maintained perfectly, and the house was comfy. Once the Hyfire was tied into the ductwork, we had a problem of too much hot air going to the 2nd floor, but the downstairs remained steady with the temp. At that time we had the furnace fan operating manufally and could only have it run on low, so poor airflow. Now I'm cold, overnight temp is not being maintained, and I'm ready to put the regular furnace on!
