Hey, I don't think you need to go that high. In the past, I simply used hot water from my house, which normally doesn't exceed 120-130F depending on your water heater, but obviously cools down rather quickly. Recently I've used a sous vide cooker and set it to 110-120F. I've had good results with both.
