Adviace Rheostat Variable Speed Control
Best for versatile wiring. This complete kit includes a rheostat, locking nut, knob, double-sided tape, and male fast on connectors, making it suitable for various fireplace blower kits, wood stoves, and fans. You manually rotate the knob to adjust speed, starting at a low setting and increasing to high as needed. It’s a straightforward upgrade for those who want simple, tangible control instead of preset automations.
Who it’s best for: DIY homeowners needing an all-in-one replacement with easy installation and universal fit. Limitations: the kit relies on manual adjustment rather than a thermostat-controlled auto-turn-on feature.
Midwest Hearth Fireplace Blower Speed Control
This is a true replacement kit designed to fit most gas fireplace inserts and wood stoves with standard OEM holes. It includes a rheostat, knob, and mounting nut for a complete panel-mount installation. Notably, it features a definitive off position, allowing you to completely cut power to the blower when not in use. This can reduce unnecessary energy draw and fan noise.
Who it’s best for: Those upgrading older blower assemblies or installing a variable speed control into a standard panel without extensive rewiring. Caution: verify that your unit’s OEM holes align with the kit’s dimensions before purchasing.
Leviton Trimatron Rotary Fan Speed Control
Leviton’s Trimatron offers a slim, easy-install option for shallow wallboxes. It provides full-range control of a ceiling fan or fireplace blower and works with existing wiring without requiring a neutral. This makes it a practical upgrade for single-pole applications when space is tight and a soft, continuous speed adjustment is desired.
Who it’s best for: Homeowners updating a single-gang wall outlet to control a blower. Limitation: ensure the motor type matches the control’s compatibility for continuous operation.
Leviton Full Range Variable Fan Speed Control
This full-range control by Leviton is designed for tight spaces and includes a built-in radio/TV interference filter. It’s suitable for ceiling paddle fans and other blower systems with compatible motors. The full-range rotary design enables precise tuning from very low to high speeds, making it a robust option for environments where quiet operation at reduced speeds is important.
Who it’s best for: Users needing fine-grained speed control with interference filtering. Limitation: verify compatibility with your blower motor type and amperage before installation.
KBMC-13BV (UR) Variable Speed Fan Control
KB ELECTRONICS offers a fan speed control suitable for PSC and split-phase motors with adjustable minimum voltage calibration. This makes it a practical choice for applications requiring a tailored speed floor and smoother ramping across a range. It’s particularly relevant for installations where motor type varies or when slight calibration adjustments improve performance.
Who it’s best for: Those needing adjustable minimum speed to prevent stalling or overly slow startup. Caution: confirm motor compatibility and voltage requirements before purchasing.
Hiorucet Fireplace Thermostat & Rheostat
Hiorucet provides a universal thermostat and rheostat control kit suitable for a wide range of brands and models, including Heat N Glo, Heatilator, Napoleon, and Lennox. It turns the blower on and off automatically based on a set temperature, with a typical activation around 120°F and shut-off near 90°F. The specified adjustable range is from 65% to 100%, allowing a balance between warmth and efficiency.
Who it’s best for: Those seeking thermostat-based automation to maintain comfortable living spaces without manual adjustment. Limitation: auto-activation depends on ambient temperatures and may require ceiling clearance for installation.
Durablow Fireplace Stove Blower Control
Durablow’s model is a straightforward rheostat-based speed control designed for fireplace fans and blower kits. It provides adjustable speed with a simple on/off behavior, making it a solid option for users who want reliable, no-frills control over their blower speed. It can be particularly effective for classic wood-burning setups or retrofits where simple wiring is preferred.
Who it’s best for: Those who want a dependable, budget-friendly rheostat for basic speed adjustment. Caution: check that your blower’s electrical specifications align with the unit’s amperage and voltage rating.
Buying Guide: How To Choose The Right Fireplace Fan Speed Control
- Motor Type And Compatibility: Confirm whether your blower uses PSC, split-phase, or shaded-pole motors. Some controls are labeled for specific motor types; using an incompatible control can reduce performance or damage the motor.
- Installation Space: If you’re limited on wall or panel depth, consider slim-profile options designed for shallow boxes (like the Leviton Trimatron).
- Control Type: Choose between rheostat (continuous speed adjustment), rotary full-range controls, or thermostat-based controls. Thermostats automate on/off with temperature, while rheostats give manual precision.
- Definitive Off And Power Savings: A “true off” position helps eliminate phantom power draw and reduces noise when the blower is not needed.
- Electrical Ratings: Verify voltage (usually 120V AC) and current rating (amps). Exceeding ratings can be unsafe or inefficient.
- Noise And Stability: Look for controls with smooth ramping and low hiccup or noise at lower speeds, especially in living areas.
- Brand And Availability: Reputable brands often provide reliable parts and easier replacement parts if upgrades are needed later.
Frequently Asked Questions
- What is a fireplace blower speed control? It’s an electrical device that adjusts the speed of the blower fan that circulates warm air from a fireplace. It can be a rheostat, a rotary full-range control, or a thermostat-based switch.
- Do I need a thermostat-based control? Thermostats automate fan operation based on temperature, which can improve comfort and efficiency in larger rooms or open spaces.
- Can I install these myself? Many are designed for DIY installation in standard panels or blower housings, but verify wiring requirements and safety guidelines for your model.
- Will a variable speed control save energy? Yes, by reducing blower speed when full heat isn’t required, you can lower energy consumption and reduce noise.
- What should I check before buying? Check motor type compatibility, voltage, amperage, space constraints, and whether you need manual control or automated thermostat features.
- Is the “off” position important? A definitive off position can cut power completely, reducing wear and avoiding unnecessary energy use when the fireplace isn’t in use.
