Rated 5 out of 5 by from Excellent, hot, long lasting heat tape! We've been using this heat tape on machinery in our shop for 4 or so years. It runs at 400 degrees (highest setting) all day; the adjustable heat dial is great. It's very hard to find a quality, flexible, wipeable, HOT, heat tape in varying lengths (trust me I've searched high and low before I found Omega). We do need to replace it after 2-3 years simply because the tape cracks due to heavy use, but it still heats great even then. I would imagine if the tape was used in a more traditional placement it wouldn't crack at all (ours is looped tightly in and around tight small fittings). It's very easy to use, the "cool" tab at one end of the tape comes in handy for positioning when hot (if needed). Will be using these unit for many years to come. Omega has always had great customer service all these years as well. Thank you!

Rated 5 out of 5 by from Makes Steam Works well used as a steam boiler for a steam expander prototype.

Rated 2 out of 5 by from Heat tape failure I bought 3 heat tapes to heat some valves to allow our product to stay warm. The adjustment of the tape is so course it is either too cold or scorching hot and burns our product. We were forced to remove them from our system.

Rated 5 out of 5 by from Works as described The product works as described and we are not disappointed. We find it actually runs a little hotter than the maximum temperature listed. Overall very easy process with Omega as always.

Will this unit draw current when the ambient temp. is above freezing, and no protection is required?

Asked by: Roger45
Thank you for your inquiry Roger45. No matter what you set the thermostat to (10 to 218°C (50 to 425°F)), the heater will always draw current to maintain the set temperature.

Does this product require any controller to control the voltage or would it be safe to plug into a typical outlet? What does this product require that is not shown here? Thanks

Asked by: Tak51
The HTWAT series heating tape with built-in thermostat can be plugged into a standard 120 volt outlet directly. A separate controller is not needed as this heater includes an adjustable thermostat to control the temperature.
