Heater Specifications
Below, we provide a breakdown of the wattage and amperage of most of the Premier Heaters we make. This will aid in choosing the correct controller for your system as your controller must be able to handle the amperage requirements of your heaters, no matter what controller setting you use. For example, if you set your controller to operate at 30%, the heaters will draw their full amperage 30% of the time. The other 70% of the time they will be off.

NOTE: Our competitors often quote what they consider the high power requirements of our Premier Heaters. It is important to note that the ratings quoted below are true if your controller is set to operate at a 100% setting. To clarify, if you set your controller to operate at 30%, the heaters will draw their full amperage, but only 30% of the time. The other 70% of the time they will be off. Also, these heaters are intentionally designed to generate more heat than our competitors heaters as they are designed to perform under ALL conditions.

Attaching Heaters
Generally, our heaters wrap around your optics, label side out and are held in place by elastic/Velcro attachments. The heaters for Newtonian/Dobsonian Secondary Mirrors, depending on which model you purchase, are either placed on the backside of the secondary and can be held in place by using the polyester batting found inside the secondary mirror holder (heaters #2016, 2017, 2018, DG-1, DG-2, DG-3) or will wrap around the secondary mirror stalk (heaters #2028 & 2028-S). Newtonian Primary Mirror Heaters sit behind the primary mirror in contact with the back side of the mirror. Your mirror holder must allow for removal of your primary mirror to accomodate a primary mirror heater.
