Always check your pitot heat, no matter if you're planning IFR or VFR.
I usually have a buddy feel the probe while I switch on the pitot heat and look for an ampere load..
A prolonged period of pitot heat with engine off is not good for your battery, specially in the winter weather that is striking Europe right now.
Having your flying buddy feel the heat also avoids burning one's hands..
These things get very hot.. Be cautious
