| PREMIER HEATERS |
 |
We have heater systems for virtually any optic or electronic device used in amatuer astronomy and outdoor photography. They are designed to keep them functioning and moisture free in humid and/or cold weather.
The Premier Heater line is our flagship brand and our highest quality heater. They are built of the highest possible quality materials and the heaters are custom built to our electrical specifications. These are not off-the-shelf heaters! We use the best quality velcro, elastic and flex heaters available for this line. The cables are cold flexible down to temperatures of -40 and the cable housing is custom make for Kendrick to our specifications. Our competitors cannot make this claim.
Our heaters have been built to use only as much power as necessary and thereby not waste energy. They have sponge insulation and infa-red reflecting material on one side to help direct the warmth generated by the heaters into the optics. Because of this, less energy is needed to keep your optics moisture free.
Our heaters wrap around your optics, label side out and are held in place by elastic/Velcro attachments. Telrad and Rigel Finder heaters are held in place with an elastic band. The heaters for 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). The .965", 1.25" and 2" heaters are considered eyepiece heaters. The 1.25" and 2" are also heaters for certain camera lenses and binocular objectives. Larger camera and binocular lenses will, of course, require larger heaters. Newtonian Primary Mirror Heaters sit behind the primary mirror in contact with the back side of the mirror. Your mirror holder must be allow for removal of yor primary mirror to accomodate a primary mirror heater.
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.
NEW!! Introducing our newest heater in the Premier Heater line, the DEW-Minator Large Eyepiece Heater!
This heater has been designed specifically for the ever increasing line of large format eyepieces available to the amatuer astronomer. It provides plenty of power for those cold or really humid nights yet can be adjusted (via a Kendrick controller) for very mild, low power operation if your conditions call for it.
Like all our heaters, it has a sewn in, heavy duty elastic strap to allow you to securely fit it to any of your large bodied eyepieces.
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.

The table below will help you to determine which heater is the right one for you scope.
If moisture has already condensed on your optics, we recommend covering the optics, turning the heaters on high and waiting 20 to 30 minutes. Once the moisture has cleared, lower your controller setting and resume observing.
