I hear ya. Need to start weighing wood, over time you'll get a good feel for how much to load and also your burning rates in order to easily compute how much to load based on outside temp. Downside is your wife may try to commit you to the loony bin.I have to be careful how much I feed cause its not uncommon to wake up in the middle of the night to 78-80! It's 29 here now and it's 74 and climbing and I've done my partial load for bed.
It's 12° here and supposedly on it's way down to single digits and I'm waiting for my small 16lb load from after work to pretty much disappear before loading tonight's load. House is also 74° (was 75° a minute ago) and Kuuma is set to minimum burn. Still running the slow blower speeds with great results too.
