Hey there! I've created a logo for you. No.7 is the first design I made. It consists of 6 blue stars representing the high quality of your products, the negative space in the middle makes a snow flake, showing the cold the truckies drive in. I then added the circle to represent the cold to hot (blue to red) that your heaters will achieve. Entry 6 I added two red heat waves. This makes the design more interesting however I think in the simpler one you can see the snowflake shape better. Let me know what you think. I'm happy to make changes to colours, fonts, etc if you like. :-) Hope you like it!
