I have an oil space heater, but I can't leave it on all day. Not only does it not actually affect the room temp much except the few feet directly around it, they really cost a lot to run 24/7. I'd be very open to insulating the outside of the tank with that thick pink foam, and using a RHP panel rated above the tank needs, if that would be enough. I'm waffling on it so much, but this 8x2x2 is only $300 and it seems like a massive waste to pass on
