Rated 4.6 out of 5 by 46 reviewers.
Rated 5.0 out of 5.0 by Compact and powerful We bought a forced air heater for each of our rooms and glad we did. We bought a house with no gas that had rotted old floorboard heaters and finding compact but powerful units at a decent price was a challenge until we found cadet. Installation was a lot easier than expected. 3 of our rooms are very large and we were concerned they wouldnt do the job, but I was wrong. They work great and look great doing it! March 27, 2015
Rated 5.0 out of 5.0 by Great product and service very happy with product. service by your Vancouver staff was outstanding March 31, 2015
Rated 5.0 out of 5.0 by Great product and service The supply house could not supply a unit .I found it on line it saved costly repairs of the wall. The unit is a quite smooth running great for the waiting room. March 27, 2015
Rated 5.0 out of 5.0 by easy install, impressive performance Installed in a poorly-insulated back room used as an office. 240V circuit was in place, left over from old baseboard heat. Drywall cut and stud mounting was easy, as was electrical connection. 4000W Cadet quickly heated room from 55F to 70F, and held temperature through the day by running approx. 10 minutes on and 30 minutes off. This kept the temp between 68-70F. For an 8-hour day at $0.12/kWh... my math shows about $1.50/day operating cost. A bargain to heat an icebox of a room! November 12, 2012
Rated 5.0 out of 5.0 by FREAKING AMAZING!!! I have a 2 car garage that is uninsulated and is constantly cold no matter what kind of heater or how many I have tried, I installed this heater (with a on of switch to turn off during summer as other reviews stated it doesnt actually turn off) and with in no time my garage went from 20 to a nice cofortable 50 and it stays there. This worked so well I installed one in my moms garage so she no longer worries about her pipes bursting March 12, 2015
Rated 4.0 out of 5.0 by Quiet enough, but not as "hot" as I expected. Cadet products are always well built and well documented. I do wish that I had an amp meter to see if this is really drawing the amps and watts it says it is drawing. For a 4,000 watt heater, it seems just a little weak. But it certainly runs quietly enough. But it doesn't come, as a kit, with an option without the built in thermostat. So to add a thermostat means having to leave the built in thermostat in place, but cut the wires and put the knob on as though it is there. Wish there was another option. April 10, 2015
Rated 5.0 out of 5.0 by Nice Value Easy install and nice heating capacity. This unit really warms up a room quickly. 500sq ft basement room. March 31, 2015
Rated 5.0 out of 5.0 by Heater The heater was easy to install and started warming the room as soon as we turned it on. March 25, 2015
