Product Description

Kendrick Premier Brand heaters are famous for their durability and outstanding performance. We use the highest quality components available and they are covered by our outstanding 2 year warranty. 

Our finished heaters and dew controllers are all assembled here in Canada by us in our shop, as are all Kendrick products. We test 100% of our heaters for functionality before shipping. This ensures the highest quality control for everything we make, and this is something we take quite seriously. Our heating elements are custom built to our electrical specifications and they are made of the highest quality materials. These are not off-the-shelf heaters! We use the best quality Velcro, elastic, and connectors available. The heater cables are cold flexible down to temperatures of -40C and the cable is custom made for Kendrick. It is not available anywhere else. As well, our cables are engineered to be the proper gauge for the wattage they require and are not simply repurposed RCA audio cables, which is what our competitors heaters use. The competitors’ repurposed RCA audio cables were not designed to handle the electrical current requirements of dew heaters, causing them to burn out or break over time.

How to Use

Our Premier Heaters require the purchase of one of our controllers which can found at this link. Our systems are all 12 VDC.

We recommend that you put your heaters in place at the beginning of an observing session and turn your controller on right away. For Premier Heaters, or heaters for Newtonian or RC Telescopes, we recommend a controller setting that represents about 20 to 40%.

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.

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 accommodate 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 five(5) 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-C - for large-body eyepieces, medium sized camera lenses, and small refractors. Ideal for tube diameters 2.5” to 3.5”.
• #2006-L - for large body 1.25" and 2" eyepieces (For example: Televue's Naglers, Ethos and Delos, Celestron's Lumina eyepieces, Explore Scientific's eyepieces, etc).

This heater has been designed specifically for the ever increasing line of large format eyepieces available to the amatuer astronomer. The heater is the same length as our 2006 2" heater but it is extra wide to give extra coverage to those really tall eyepieces. 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.
