PELONIS Fan Forced

Disk Furnace V Ceramic Heater

The Pelonis Disk Furnace V (HC-461) is the latest in well designed Fan Forced Ceramic Space Heaters that consistently raise the bar for efficient portable electric heating.


The DFV is one of the most compact out there yet it packs a serious punch when it comes to turning 1500 watts of power into usable heat, this thanks in large to their patented ceramic disk design that optimized the heat for wattage value by nearly 80%, in other words, the power you put in produces nearly 80% more heat!

For example, the typical forced air conventional element heater produces 140 f degrees at 1500 watts but the Pelonis DFV produces a respectable 228 f degrees at the same wattage!
With all that heat, now you need to distribute it into the room and the DFV does that with a ball bearing (not bushing) variable speed fan motor and a tunnel design that brings in the cold air through an easy clean particle filter and exhausts it as a steady stream of heat, a journey of under 5 inches in a perfectly tubular, cool to the touch, ducted fan which forces the heat out two feet where it then begins to rise.
Controls are all digital and easy to read and understand on the lower side panel. Set the temperature you want (easy to read large LED), push the Power button and let it do the rest... but before you do that,
always be sure to read and setup per included instructions.


Once your target temperature nears, the heater will automatically wind down, lowering heat output, energy use and fan speed (low power mode = 700 watts or fan only idle mode at 7 watts), which is supposed to constantly monitor and adjust to maintain a constant room temperature...we still prefer the more efficient on off thermostatic control.
The DFV is one of few portable heaters actually designed to run for long periods of time at a stretch.
Easy to set up and move thanks to its compact size (Overall unit size is LxWxH: 9.3" x 7.1" x 9.5" Weight: 5 lbs. Power: 110-120V/60Hz Color: Black) and safe to use when directions are followed.


Safety features include overheat protection, front / side tip over off switch, power off auto reset (when the power goes off, you cannot just plug it in and go you need to reset your temps and then push the power ON button).
Bright LEDS in the front let you know when power is on and temperature set controls are active, visible day or night.
Cleaning the rear mounted filter occasionally is a good idea for best performance with a simple pop out then water rinse and dry in under 5 minutes.


We have found the DFV to be very efficient... (sample room tested was 8' X 9'), heat from 58 degrees f to 69 f...28 minutes vs. a single conventional (1500 watt) "milk house heater" took 60 minutes to go from 58 degrees to 69 degrees in the same room. That represents a conservative 53% savings for the Pelonis in both time to heat and power saved.
All in all, the Pelonis HC 461 DFV is a well designed ( almost over-designed) product with few problems.

The Pelonis name is backed up by personal service and knowledgeable people, everyone there seems to live and breathe the product as information was abundant and if you want more technical info, simply drop by their website and you can find a lot of great information on their products, they do information very well! TECHNICAL INFO
I personally had many questions of which all have been answered by the top man, Sam Pelonis (on many occasions), and THAT means a LOT in this day and age of disconnected Corporations...thanks for putting up with my million questions Sam!


The HC 461 is priced at $99.00, and warranted for 7, yes, SEVEN YEARS... or you can opt for its twin brother the 455 which uses manual controls with a 5 year warranty at only $59.00! No matter which you choose, you will stay warm this winter without breaking the bank!

HC-455 Manual Controls: In automatic mode you set the temperature with the dial indicator and it will maintain that temperature indefinitely + or -10 degrees.
MANUAL mode: No thermostatic function with this one, you now use the dial to select from a tiny trickle of heat to a lot of heat, good for keeping hands warm in protected outdoor projects or in unheated warehouses, an excellent multi purpose heater! LL
