Kendrick Premier Heaters
Our Premier Brand heaters are the best heaters made and they produce considerably more heat than any other brand. You don’t always need the extra heat, but there are going to be times that you are glad to have it. Premier Heaters are designed to be used with cameras and camera lenses, telescopes optics of all kinds, binoculars and temperature sensitive electronics.
Premier Heaters require the purchase of one of our We have heater systems for virtually any optic or electronic device used in amateur astronomy, outdoor photography and medical operating rooms. They are designed to keep electronic devices functioning and optics moisture free in humid and/or cold working environments. 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. All our competitors use cable that gets stiff and brittle in cold environments. |
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) 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.
Eyepiece Heaters
Customers regularly ask if eyepiece heaters are necessary. They are just as much a necessity as the heater for the main lens or mirror in your telescope. In cool environments, moisture from your eye condenses on the eyepiece glass and without heat, is very difficult or impossible to remove.
We manufacture four sizes of eyepiece heaters:
- #2004 - for eyepieces on finderscopes.
- #2005 - for 1.25" eyepieces and that do not have a huge body (For example: Plossls, Vixen Lanthanum and similarly sized eyepieces).
- #2006 - for larger bodied (but not massive) 1.25" and 2" eyepieces (For example: Baader Hyperion and Orion Stratus eyepieces).
- #2006-L - for large body (tall) 1.25" and 2" eyepieces (For example: Televue's Naglers, Ethos and Delos, Celestron's Lumina eyepieces, Explore Scientific's eyepieces, etc).
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.
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.
