1 Set White Double Pole Line Volt Thermostat Cover With Line Volt Knob

From the Aryeielsow Store, this set mirrors the functionality of the single kit while emphasizing compatibility with older D22 thermostats. The design features a clean white finish to maintain a crisp wall profile and a simple knob to facilitate temperature adjustments. The product emphasizes fit compatibility and a modernized look for homes that still rely on line-voltage controls. It remains incompatible with TPI 1A22 models, underscoring the importance of verifying old thermostat types before upgrading the cover plate.
Cadet Com-Pak Electric Wall Heater Vertical Grille Kit (CS/CGW)

The Cadet Com-Pak grille kit is engineered for vertical wall heater installations, compatible with CS or CM models (CGW, Part 67079). The grille delivers a practical, edge-free finish with a powder-coated white surface, contributing to a safer, more cohesive heater appearance. Installation is straightforward: place the grille over the heating unit and secure with included screws. The kit supports both new installations and replacements, delivering a sleek, finished look while safeguarding the surrounding wall area from heat exposure and minor hardware contact.
Wall-Mounted Patio Heater Cover (36.5″ L)

This weather-resistant patio heater cover from Birheatry Store offers a practical outdoor solution for protecting wall-mounted heaters. Sized at 36.5 inches long by 9.5 inches high and 6.5 inches wide, it is designed to fit a broad range of standard mounted heaters. The cover uses 420D Oxford fabric with PVC-coated polyester for water resistance and durability, with reinforced features like a double-sided drawstring to secure the bottom edge against wind. It is important to measure your heater to ensure a proper fit, as the cover is listed as a protective accessory rather than a heater unit.
Cadet Com-Pak Electric Wall Heater Grille Kit (Almond)

The Almond variant of Cadet’s Com-Pak vertical grille kit provides a warm, neutral finish to blend with light wood tones or beige interiors. Made in the United States, this grille kit emphasizes a ready-to-install approach for CS or CM model heaters. Like other Cadet products, it focuses on easy installation, secure fit, and a clean, finished appearance that complements both contemporary and traditional spaces. The almond finish can subtly harmonize with warm color palettes while maintaining heat safety and unit accessibility.
Buying Guide: Key Considerations For Electric Wall Heater Covers
- Compatibility and fit: Confirm model numbers and thermostat types (for line-voltage covers) before purchasing. Old-style D22 thermostats require specific cover dimensions to ensure a flush wall appearance and proper knob access.
- Material and durability: ABS plastic and powder-coated grilles offer protection against dust, impact, and moisture in indoor spaces. Outdoor covers use weatherproof fabrics like 420D Oxford with PVC coatings for extended longevity.
- Finish and aesthetics: White or almond finishes are common, providing neutral options that blend with most decors. Gold-plated lettering adds a touch of elegance for traditional interiors.
- Installation: Look for covers and grilles that ship with hardware and clear installation steps. Simple, tool-light installation reduces the risk of damage and ensures a secure fit.
- Safety and accessibility: Ensure the cover or grille does not obstruct controls or heating vents. A well-fitted cover helps protect children and pets from exposed heating components while maintaining easy access for adjustments.
- Indoor vs outdoor use: Indoor covers prioritize aesthetics and dust protection, while outdoor or patio covers emphasize waterproofing and wind resistance. Measure your unit to choose the correct size and protection level.
- Maintenance: Choose washable or wipe-clean surfaces where possible. Durable finishes resist wear from routine cleaning and handling.
- Brand and warranty: Reputable brands like Cadet offer standardized parts and replacement options, which can simplify future maintenance or part upgrades.
