We've had record heat and number of days over 100 in Texas this summer. I noticed my H2W second fan causing boiling of the fuel in the right tank when full almost immediately after installation. A couple of layers of insulating reflective foil tape fixed that problem. I'm glad to see H2W including the tape now, but a deflector would be a better solution. I have the 88 deg (Celsius) switch and I've had no problems of overheating in the TX blast furnace.
