I had the same thoughts only last week while I was refiliing Silvias tank. I wondered if having the tank heated up to say 60 deg would help stability. I thought it would be fairly easy to install an element in the tank. I wasnt arsed following it up any further as Im fairly happy with Silvias stability and dont have the time or the ability to tinker with serious tronics. Plus I would be concerned about the effects of heated water on the tank and feed tube plastic. I guess a metallic tank would need to be installed for long life.
