Silicone? Did switching to a smaller stove decrease burn times? I have to do a lot of cold starts, because a lot of times no one is home to keep it going.

Yes it did. With the Englander 30 I could easily go overnight. With the Englander 13 I can go overnight but I have to choose the proper wood and put it in right before bed and hold my mouth just right.

My house is insulated so well that a lot of times I have a hot fire in the morning, let it almost burn, out and then use the last few coals in the evening to get it going again.

If I keep it going all day I use the same method but with less wood.

In my case the smaller stove was the fix for almost all my problems. Seems most people want to go the other way and get bigger stoves.

Silicone..seems the consensus is not to use it. The silicone topic got carried over from another thread. We were talking about high temp silicone and single wall pipe. Probably not related to your post.
 
Yes different thread. I might have to go bigger next year. Jotul f 400 heats the house fine if someone is home to tend to it. That is often not the case so keeping it going 24/7 is a challenge.

This was the reason we upgraded. The F400 is a beautiful stove, but it's hard to heat 24/7 with it when temps get cold and burn times decrease due to pushing the stove harder for heat.
 
OK dumb question. When getting stove up to temp, do I go by what the stove temp gauge says or do I go by what the IR gun reads?(IR gun temp taken from middle of the stove plate). For example. When I take temp with the gun trim the middle of stove plate and it reads 600°, the stove temp gauge typically reads 400°. Maybe that is why my flue temps are not as high as they should be. Even though gun gives a high reading from middle of plate, say 600°. The stove is actually at a lower temp per the stove gauge.

Stove temps will vary depending where they are taken. Take IR reading from the same location as is suggested for the thermometer location on the stove top. See if the stovetop thermometer is reading correctly.

Some stoves read hottest where the flue gases focus before heading up the flue outlet. Jotul and other companies seem to find that location less helpful and picks a more average location in their recommendation.
