Most heat tapes warn against sealing the tape with insulation to prevent overheating of the tape. Since it is a resistance heating medium it has a limited lifetime and once it is buried 4 feet deep, it is there to stay even after it burns out. There are no inside the pipe heaters and if there were, you could have a short circuit or shock hazard when it went bad. The only good solution is to allow the water to drip somewhere to keep the temperature of the water from dropping into the freeze zone.
