While it is impossible to give you a quantitative answer without knowing more details about your house and system (e.g. how they set the fan speed in each setting) in my opinion it is better to have the system on Fan setting.

What it does is running the blower motor even when heat/AC is not actively heating cooling. While running the fan does consume electricity, you end up with a more uniform air throughout the house. 

Should I leave the fan switch on my thermostat set to fan rather than auto?
I'm a beginner drummer (only had 4 lessons so far) and I am thinking about buying an electronic drum kit. I've read this post and this post on buying a beginner drum kit, but both seem to be almost entirely about buying an acoustic kit.


What are the differences when buying a beginner electronic drum kit (as opposed to acoustic)?


I'd like the kit to last for a while, so


How long will a beginner kit suffice, or do you outgrow it quickly? Is there a big difference between beginner, intermediate or pro electronic kits when it comes to sound quality?


Finally, one of my options is to buy a second-hand kit, so:


What are the things I should be looking for or avoid when checking out a second-hand electronic kit? 


I hope these aren't too many questions. I'm willing to spread them over multiple questions if that's better. 

I'm not sure if it matters, but my budget is somewhere around 500-900 euro's (that's $660-$1200) and I'm hoping I can use the drum kit for both practicing and playing a few easy songs in my hobby band (perhaps even at a gig).
