Insulate outdoor pipes next to wall

I live in SoCal where I have an outdoor water heater. The pipes run ~6ft outdoors before they go into the house, and they run very close to the exterior wall (maybe 1/4" or less).

I really want to insulate that pipe. In the winter, I have to run the shower for a couple minutes before the water warms up. I bought some rubber insulation, but since the pipe is so close to the home exterior, I could not squeeze it between the pipe and the house. Are there any options for insulating an outdoor pipe that is next to a wall?
