Our Verdict

The Dimplex is a powerful baseboard heater with an extensive feature set and impressive range. We especially love that it can be hooked up to other heaters for synchronized heating across a whole house.


  • In-unit thermostat
  • Compact design


  • Too powerful for smaller rooms

The Dimplex PC6025W31 is an efficient and versatile heater that works for a variety of room sizes, which is why it topped the rankings in our best baseboard heaters guide. It’s compatible with multiple wiring voltages which means it can be used to heat either a single room, or it can be synced up with other heaters to control the temperature across a whole house.

It has a compact design, but thanks to the high wattage and clever vent system it can still be used to heat up larger rooms - in fact, we’d go as far as to say it’s too powerful for smaller rooms.

Dimplex PC6025W31 review: Design and features

The Dimplex is compatible with more wiring schemes than any other baseboard heater we reviewed, including the Cadet 8F2000W, which only uses 240-volt wiring. It comes with the necessary wiring for traditional 120 and 240-volt wiring, but it also works with 208 and 347-volt wires for three-way systems if you’re hardwiring heaters to the multiple thermostat controls. Depending on the wiring you use, you can achieve more than 2,000 watts of heat output at maximum power.

At its highest level of heat output, this electric baseboard heating unit produces more than 8,500 btu. This means the device can heat well-insulated rooms up to 400 square feet with relative ease. For older homes lacking in insulation, this unit should still heat 200 square feet comfortably.

This baseboard unit has been smartly engineered; it offers a modern look and innovative features. The heating element is made of nickel-chromium and enclosed within a steel sheath to discourage rusting and prolong the life of the heater. Across the element are multiple upright aluminum fins designed to enable upward airflow. This ensures more heat moves toward the upper vent and outward into the room, with less chance for heat to be absorbed into the wall or other parts of the heater. This allows the unit to heat a room faster than a typical baseboard heater.

This baseboard heater offers an incredible level of efficiency thanks to the well-designed heating element and top vent. It offers heating output comparable to models roughly twice the size. This leaves you significantly more room for decorations and furniture.

The Dimplex PC6025W31 comes with a built-in thermostat. This is a rare feature. In fact, the other models we evaluated all require an external thermostat in order to operate. This unit’s electronic proportioning thermostat allows you to control the temperature directly from the unit via an RF transceiver that also enables heater-to-heater telegraphing.

Besides working wirelessly with a handheld remote and wall controls, the unit can also communicate with other Dimplex electric baseboard heaters. This allows you to set up whole-home temperature syncing so you can adjust temperature levels throughout your home from a central hub. The CSA-C828-compliant controls within the device allow you to set the temperature for this heater in increments of a half-degree Celsius or one degree Fahrenheit.

To control multiple Dimplex heaters wirelessly, you have to purchase a wall-mounted remote control. This accessory utilizes radio frequencies to control each convector and saves you the cost of installing new wiring between each heater and running them directly to a thermostat. You can purchase additional remotes for each heater, though having a central remote makes it easy to manage the temperature of your entire home.

Dimplex PC6025W31 review: Warranty and support

This baseboard heater comes with two warranties that cover different parts of the unit. A one-year warranty protects the entirety of the unit, including the 20-gauge steel construction and the installation wires and ventilation. The most important part of baseboard heating, the heating element, is covered by a 10-year warranty. When you purchase this unit, you have to register the product to validate the warranty period, after which you can send in failed parts for repair or replacement.

Dimplex offers a comprehensive support department with contact methods that include web forms and phone lines. In addition to these direct customer support options, the company also offers technical and troubleshooting guides, training videos, FAQs and even heat loss calculators. 

The heat loss calculator is a unique feature, allowing you to identify all aspects of the room you plan on heating, with information about wall insulation, window types, door sizes and more. The tool then calculates the amount of heat loss in terms of wattage, which helps you decide which heater would most effectively heat the room.

Should you buy the Dimplex PC6025W31?

The Dimplex PC6025W31 earns its rank as our top baseboard heater due to its efficient and versatile design. Its top vent allows it to distribute heat quickly throughout a room. Its built-in thermostat allows you to control the unit directly without an external thermostat. 

Those wanting whole-home syncing can take advantage of the three-way wiring compatibility and a separately purchased wireless remote to link multiple Dimplex heaters to the same thermostat. Its 10-year warranty, which is longer than most, is reassuring when you purchase a product with so many advanced features.
