preheat

I have a used Reiff Preheater for a 4 cylinder engine. I bought it about a month ago. It was installed on his airplane and worked before I bought it. He said it was 2 or 3 years old. The owner of the airplane I purchased it for decided not to install it. $150 plus shipping firm.

Purchasing a 1962 PA-28-160, and will be on a tie down in Tennessee (due to lack of hangar availability and funds). 30SMOH, new cylinders (not sure if ECI or Lycoming), I want to avoid excessive wear. I'm looking into a 100°industrial heated blanket for preheat. Temps regularly get below 40°...
