Oil Filled Electric Baseboard Heaters

Oil-filled electric baseboard heaters are self-contained hydronic heating units that circulate an environmentally friendly, non-toxic, non-hazardous fluid through an enclosed element to deliver gentle, steady warmth without a boiler, plumbing connections, or refilling. At SupplyHouse, this category features the Cadet SoftHeat EBHN Series, a lineup of liquid-filled hydronic baseboard heaters engineered to produce lower surface temperatures than standard electric baseboards, reduce airborne allergens, and retain residual heat even after the thermostat shuts off. The Cadet SoftHeat EBHN Series is available in 240V, 208V, and 120V configurations, covers wattages from 500W to 1,500W, spans lengths from 35" to 83", and carries ETL listing. The fluid design makes SoftHeat an application-specific choice for bedrooms, nurseries, and spaces where allergy sensitivity or the safety of children and pets near the baseboard is a priority. All models are hardwired and all require a thermostat purchased separately.

The EBHN500-1W (SKU EBHN500-1W) is a 35" Cadet SoftHeat left end wire hydronic baseboard heater at 500W and 120V, serving residential installations where only a 120V circuit is available. The EBHN500-1W provides spaces up to 75 square feet with the same fluid-filled hydronic warmth, lower surface temperature, residual heat retention, and high-temperature safety shutoff as the 240V SoftHeat models. ETL listed. Thermostat sold separately.

Cadet SoftHeat EBKNW Thermostat

The Cadet EBKNW (SKU EBKNW) is the SoftHeat Non-Programmable Double Pole Baseboard Mounted Thermostat, the dedicated thermostat accessory for the Cadet SoftHeat EBHN Series. The EBKNW operates at 240V, 208V, or 120V, is rated at 25 amps, features a simple non-programmable dial control, and uses a double pole bimetal thermostat with positive off switching. The EBKNW mounts directly at the baseboard and is designed specifically for the SoftHeat EBHN and EBHA hydronic baseboard heater series. It's sold separately from all heater models in the lineup.

BUYING GUIDE / HOW TO CHOOSE

Selecting a Cadet SoftHeat EBHN oil-filled electric baseboard heater starts with voltage. The circuit at the installation point determines which models are available. A 240V circuit is the most common residential configuration and supports the full EBHN lineup from 500W through 1,500W. A 208V supply in a commercial or multifamily building with three-phase distribution calls for the dedicated 208V models (EBHN500-8W, EBHN750-8W, EBHN1250-8W), though the 240V dual junction models can also operate at reduced wattage on a 208V circuit. A 120V circuit limits the selection to the EBHN500-1W at 500W/35".

Wattage is the second decision. Cadet's stated coverage guidelines for the EBHN Series are 500W for up to 75 square feet, 750W for up to 100 square feet, 1,000W for up to 150 square feet, 1,250W for up to 200 square feet, and 1,500W for up to 250 square feet. Rooms with high ceilings, significant exterior wall exposure, or large windows may need more output than the square footage guideline suggests. Using the room's actual heat loss calculation rather than square footage alone gives the most reliable wattage selection.

Physical length follows from wattage. The EBHN Series runs from 35" (500W) to 83" (1,500W), with each wattage step adding roughly 12" of length. Confirming the available wall run at the installation location before specifying is required, since a 1,500W/83" unit won't fit a short wall segment that a 1,000W/59" unit would handle.

Application type is the deciding factor for choosing SoftHeat over a standard resistance baseboard. The fluid design produces the lowest surface temperatures available in the electric baseboard category, making SoftHeat the practical choice for bedrooms and nurseries where contact with the baseboard by children or pets is possible. The residual heat retention after thermostat shutoff also produces more consistent room temperatures than a dry element that heats and cools immediately with the thermostat signal.

All EBHN models require a thermostat purchased separately. The EBKNW SoftHeat Non-Programmable Double Pole Baseboard Mounted Thermostat (SKU EBKNW) is the dedicated option, mounting directly at the baseboard at 25A/240V/208V/120V. Third-party wall thermostats including Cadet T522-W and Honeywell TL7235A1003 and TL8230A1003 are also listed as compatible where the voltage and amperage match.

FAQs

What is a Cadet SoftHeat oil-filled electric baseboard heater and how does it work?

A Cadet SoftHeat oil-filled electric baseboard heater is a self-contained liquid-filled hydronic baseboard unit that circulates an environmentally friendly, non-toxic, non-hazardous fluid to deliver gentle, steady warmth without plumbing or refilling. The element heats the fluid, the fluid retains thermal energy longer than a dry resistance element, and heat radiates through the heater body and by convection into the room. The SoftHeat design produces residual warmth even after the thermostat shuts off, resulting in more consistent room temperatures with fewer on/off cycles. No boiler, no piping, and no plumbing connections are required.

What makes the Cadet SoftHeat different from a standard electric baseboard heater?

The difference between a Cadet SoftHeat and a standard electric baseboard heater is the heat delivery mechanism and the resulting surface temperature. Standard electric baseboards heat air directly across a dry resistance element with no thermal mass, producing higher surface temperatures and immediate cooling when the element cycles off. The SoftHeat circulates an environmentally friendly fluid that retains heat longer, producing the lowest surface temperatures available in the electric baseboard category, which makes SoftHeat the practical choice for bedrooms, nurseries, and spaces where children or pets may come into contact with the baseboard. The SoftHeat also helps reduce airborne allergens compared to standard resistance baseboards.

What voltage options are available in the Cadet SoftHeat EBHN Series?

Cadet SoftHeat EBHN Series models are available in 240V, 208V, and 120V. The 240V dual junction models (EBHN500W through EBHN1500W) also operate at reduced wattage on 208V, making them usable in both residential 240V systems and commercial 208V/120V three-phase buildings. Dedicated 208V models (EBHN500-8W, EBHN750-8W, EBHN1250-8W) are available for commercial and multifamily applications where a dedicated 208V unit is preferred. The EBHN500-1W is the 120V option, covering 500W at 35" for installations where only a 120V circuit is available.

What thermostat is recommended for the Cadet SoftHeat EBHN Series?

The dedicated thermostat for the Cadet SoftHeat EBHN Series is the EBKNW (SKU EBKNW), a non-programmable double pole baseboard-mounted thermostat rated at 25 amps and compatible with 240V, 208V, and 120V. The EBKNW uses a simple dial control with positive off and a double pole bimetal switch, and mounts directly at the baseboard. All EBHN heater models ship without a thermostat, so the EBKNW or a compatible third-party wall thermostat must be ordered separately. Third-party options including the Cadet T522-W and Honeywell LineVoltPro TL7235A1003 and TL8230A1003 are listed as compatible where voltage and amperage match.

What wattage and length should be specified for a given room size?

Cadet's coverage guidelines for the SoftHeat EBHN Series are 500W/35" for spaces up to 75 square feet (EBHN500W), 750W/47" for spaces up to 100 square feet (EBHN750W), 1,000W/59" for spaces up to 150 square feet (EBHN1000W), 1,250W/71" for spaces up to 200 square feet (EBHN1250W), and 1,500W/83" for spaces up to 250 square feet (EBHN1500W). Rooms with high ceilings, large glazing areas, significant exterior wall exposure, or poor insulation may require more output than the square footage guideline suggests. The available wall run at the installation point must also be confirmed before specifying, as each wattage step adds roughly 12" of heater length.
