To make your Heat-Line heating cable system more energy efficient, consider the following:
A thermostat can be added to the system in order to duty cycle the product ON and OFF to maintain a certain pipe temperature. Heat-Line thermostats are pre-set to maintain the pipe at 50°F (10°C) as this setting keeps the heating cable operating in its most efficient state with a proper safety differential of 18°F or 10°C to the freezing point.
Thermostats can be efficiently used for any length of heating cable but it is highly recommended a thermostat is considered for any length greater than 80 feet.
Other Control Devices
Remember how self-regulating heating cables work? The heating cable has the ability to vary its power output in response to temperature at every point along its circuit. As the temperature (water or air) gets colder, the heating cable automatically increase heat (energy) output in that area. As the water or air warms, the heat cable automatically reduces heat output. Now imagine insulation on your pipes. The insulation will help retain the heat inside the pipe so the heating cable will draw less energy to maintain that section of pipe from freezing. Would you put the best heat furnace in the world in your home and then not insulate the exterior walls? The answer is no. So why wouldn’t you insulate your pipes if you have the option?
Heat-Line offers closed cell polyethylene sleeves which are ¾" thick. This insulation works well as it insulates around the entire pipe and is quickly and easily installed. This insulation conserves energy and when used in conjunction with Heat-Line systems has been proven to keep water flowing in pipes above ground in temperatures below -40°C.
Combining a Thermostat with Insulation
When the thermostat sensor lead is located on the pipe under the insulation the thermostat will duty cycle the heating cable ON and OFF as required to maintain a certain pipe temperature.
The insulated pipe causes the system to come on periodically for short periods of time saving you up to as much as 80% in energy depending on application variables and amount and type of insulation used. The heating cable will remain off for extended periods of time because of the thermal insulation; this is how you conserve energy.
When installing a new heating cable or researching how to make your current Heat-Line system more efficient, it is important to consider both thermostats and pipe insulation.
