Well you're so damn hot I think you just existing in any space should generate as much heat as a small star. If you're still cold though I hear moderate exercise is a good way to keep warm. We could try that.
Well I'm pretty sure that's a thermostat in the background there on the wall, presumably increasing the setting on that will warm it up more. Oh wait you meant like a sex thing
They used to work when I had the furnace and rooftop A/Cs attached to it, but i installed a mini split last year with a remote... so those old thermos are just to tell me how different the temp is from the mini-split area to the kitchen area lol (def not because I am too lazy or distracted to take them down haha)
@LittleRedDev the RV I'm not quite sure, although that pic suggests many ways that I might be able to put you into heat, I just need to hit the right button, and hit it good!
