Our Top Picks for Dewnot Heaters Heater Accessories
The three standouts our editors recommend first — ranked by performance, value, and real-world reviews.
Made in the USA, the Dew-Not Dew Remover is a thick film dew heater manufactured for operation at 12 volts. It helps keep dew condensation from forming on the glass surface of your optical device.
SELECTING A DEW HEATER: To select the right dew heater for your scope, measure the circumference of your specific eyepiece/finder/telescope tube or dewshield. Or measure the tube/dewshield diameter - not telescope aperture - and multiply by 3.14. Pick one of the models based on the length specified. For in-between sizes, choose the next larger size of dew heater. Please measure and select the correct size BEFORE ordering, and please do NOT order blindly based on your telescope aperture as tubes
POWERING A DEW HEATER: Note that all Dew Not Dew Heaters come with a male RCA (phono plug) power jack. To power these, you need a separate 12V power supply source with a female RCA/phono plug connector. You cannot run these directly from 110/220V AC, USB, or cigarette-lighter sockets and no other power cords are included. Several companies (like Dew-Not, Thousand Oaks, Kendrick, etc.) sell dew controller units that can power and control these heater strips, or you can also look for other 12V bat
Most astronomers focus on aperture and focal length, but the real enemy of a clear view is often just a bit of humidity. The DewNot Dew Heater Strips provide a surprisingly simple solution by using a thick film design to prevent condensation from ruining your glass surfaces. Since these are manufactured in the USA and designed for 12V operation, they are a reliable staple for any serious setup. Just keep in mind that sizing is critical. You need to measure your tube's circumference rather than the telescope aperture to ensure a proper fit. Also, remember that these require a separate 12V power source with a female RCA jack, as they won't run directly from USB or standard wall outlets. It is a specialized tool for a specialized problem.

The DewNot Dew Heater Strip is a specialized 12-volt solution designed to keep your telescope glass clear of condensation during long nights of observing. Made in the USA, this thick film heater is a lifesaver for anyone tired of fighting moisture buildup on their eyepieces or dewshields. You need to be precise when sizing this up, so make sure to measure your tube's circumference or diameter rather than just looking at your aperture. It is important to remember that this strip uses a male RCA power jack, meaning you will need a separate 12V power supply or a dedicated dew controller to get it running. It won't work with standard USB or wall outlets, but once you have the right power source, it provides reliable protection for your optics.

Astrophotographers fighting humid nights need the DewNot Dew Heater Strip to prevent their expensive optics from becoming uselessly fogged. This American-made solution uses a thick film design to maintain a consistent temperature around your telescope tube or dewshield, effectively stopping condensation before it ruins your view. It is vital to remember that sizing is based on the circumference of your equipment, not your telescope's aperture, so measure carefully to ensure a proper fit. You will also need to provide your own 12V power source with a female RCA jack, as this strip utilizes a male RCA plug and cannot run directly from USB or standard wall outlets. When paired with the right controller, it is a reliable way to keep your glass clear all night long.

Your star party is hitting a sudden, frustrating wall when condensation starts blurring your view through the eyepiece. The DewNot 0.965" Dew Heater Strip acts as a vital line of defense, utilizing a thick film design to keep your optical glass clear and functional throughout the night. Since this is a specialized 12V tool, you need to be prepared with a separate power source featuring a female RCA jack, as it won't plug directly into a USB port or wall outlet. It is a precision instrument designed for specific tube diameters, so measuring your circumference beforehand is the only way to ensure a perfect fit. This American-made strip is a reliable way to protect your investment from moisture during long observation sessions.
A Guide to Selecting the Best dewnot heaters heater accessories
Prioritizing Thermal Regulation and Precision
The most significant advantage of high-quality heater accessories is the ability to move beyond 'on or off' temperature control. When browsing for accessories, look for components that offer granular control. For instance, if you are looking at external thermostats or temperature probes, ensure they feature high-sensitivity sensors. A sensor that reacts slowly to ambient changes will cause your heater to overshoot its target temperature, leading to energy waste and uncomfortable temperature swings. Look for accessories that offer digital readouts or compatibility with smart home ecosystems, allowing you to monitor real-time data rather than relying on mechanical dials.
Safety Standards and Electrical Integrity
Heaters are high-draw appliances, which makes the electrical integrity of your accessories non-negotiable. When selecting power strips, surge protectors, or specialized cables designed for heating units, always verify the amperage rating. Using an accessory rated for low-power electronics on a high-wattage heater is a primary cause of overheating and potential fire hazards. A robust accessory should feature heavy-duty insulation and, ideally, built-in circuit breakers or thermal cut-off switches. If you are purchasing mounting brackets or stands, ensure they are constructed from non-combustible materials like reinforced steel rather than plastics, which can degrade or melt under prolonged heat exposure.
Compatibility and Integration Factors
One of the most common mistakes in purchasing heater accessories is overlooking physical and functional compatibility. Not all accessories are universal. For example, if you are purchasing a specialized cover or a mounting kit, check the dimensions and the specific attachment points of your heater model. Even subtle differences in airflow patterns can render certain deflectors or shields ineffective. Furthermore, consider how the accessory integrates with your current environment. If you are adding a remote control module, ensure it operates on a frequency that won't be interfered with by other household devices, and check if it requires a specific hub to function.
Efficiency and Long-Term Maintenance
Finally, consider how an accessory will impact your long-term operating costs. Accessories such as heat reflectors or specialized insulation wraps can significantly increase the directional efficiency of your heater, bouncing warmth back into the room rather than letting it dissipate into walls or windows. When choosing maintenance-related accessories, such as cleaning kits or replacement filters, prioritize those that are easy to install and replace. A heater that is easy to maintain is a heater that will last for years. Always weigh the initial cost of the accessory against its ability to reduce energy consumption. A slightly more expensive, high-efficiency component often pays for itself through lower utility bills over a single winter season.

Quick answers about Dewnot Heaters Heater Accessories before you buy.
To maximize efficiency and safety, focus on thermal insulation covers, remote control extensions, and heavy-duty power surge protectors designed for high-wattage appliances.
No. Because heaters draw significant current, you should only use heavy-duty, thick-gauge cords rated for the specific wattage of your unit to prevent overheating or fire hazards.
Yes, high-quality insulation covers help retain heat within the unit's core and protect the exterior housing from rapid temperature fluctuations, leading to more consistent warmth.
While not strictly necessary for heat, protective silicone sleeves for remotes prevent accidental button presses and protect the device from accidental spills or dust buildup near the heater.
Use a dry microfiber cloth for most surfaces. Avoid using liquid cleaners on electrical components or remote controls. If a cover is fabric-based, check the specific care label for machine-washable instructions.
A high-quality surge protector can shield the electronic control boards of modern heaters from voltage spikes, extending the lifespan of the internal circuitry.
You can use decorative elements, but ensure they are made of fire-retardant materials and do not obstruct any ventilation ports or airflow paths required for safe operation.
