Why would a Fin who hates American Beekeeping and Keepers spend so much time on this forum is a good question (One I've asked him several times).
Ask, why Jesus Christ irritated so many people during his life, and especially after his death.
Actually, you are delivering so much wrong knowledge here.
I returned here after banning when guys wrote that I use 15W heating during winter.
After years guys have learned something from me but wrong way.
I use only heating in May and April for colony build up. And if I heat hives during winter in January on, I use 3 W heaters. Winter heating I use very seldom.
I have allways said, that get first insulated hive and after that consider, if you need heating.
