Customer Questions & Answers

Do I need to rewire for the 240volt in my home?

Asked by: Dillon
Quite possibly. Most home wiring is a standard 120v. A 240v plug will be a combination of two 120v wires attached to two separate 120v breakers. You won't need a whole house rewiring, but you will need a 240v plug installed. A competent local electrician should be able to give you some good options depending on the design of your home and where you desire the plug to be located.

You pay a little more for this heater, but it is sturdy, safe and the thermostatic controls are easily understood and the operation is simple. My only suggestion for improvement would be that the output of the heater should be increased.

Rated 5 out of 5 by from In use for 5+ Years I purchased radiant heaters to heat my insulated work shop first. They ran my bill up and were on all the time. I purchased this unit and wired it to an outlet that was controlled by a line voltage thermostat. It works great. It has two wattage settings. Normally I have it set to the low setting and keep the temp arround 50 degrees. When I am in the shop I set it on the higher setting and it raises the temp to 70 in just a few minutes. Built extremely sturdy. I am about to purchase another one for another space I need to heat.

Rated 5 out of 5 by from The real deal This heater is the real deal. It heats my insulated two-car garage with ease. It's 220 volts, so it's also efficient. I typically leave the heater on about 1/4 of the way at all times in the winter and bump it up to about 1/2 while working on projects, etc. I have not noticed any difference in my electric bill. I'm quite happy with this purchase. Sure, it's not cheap, but you get a great value in the long run. I've wasted much time and money in the past on portable heaters for my garage work shop. I've tried electric, propane and kerosene, which gives me a terrible headache. Propane is nice, but you typically only get about one workday per bottle of fuel, and that gets expensive and inconvenient. If you're looking for workshop heat, look no further. This unit is built well and does what it should without disappointment. FYI... You'll need a 220 volt outlet within 6 feet of the unit.

Rated 5 out of 5 by from The Five Star rating says it all. First, let me state I live on San Francisco's East Bay. Winters here are most mild compared to the Northeast from wench I came. My workshop here in California was previously a 3-car garage with a 12' ceiling. The two 120amp space heaters were not doing a good job of heating the entire space; I had to place them but a few feet away from my work area for any benefit. After converting the circuit breaker box to 240amp it raised the temperature in the entire shop 10 degrees in an hour. Only downside I can expect is how much my electric bill will increase now that I've doubled the output. A small price to pay for being able to work in comfort.

Rated 5 out of 5 by from Outstanding!!! Keeps the Chicago winter outside where it belongs Over the past few years our cinder block walled maintenance shop would get down to 30 - 40 degrees in the winter here in Chicago. I purchased this in the hopes of at least taking the chill out of the shop so that we could wear a sweatshirt or something instead of our winter coats all the time. We put it up on the wall about 8 feet high and to our surprise it has not only taken the chill out of the room but actually made it comfortable. The shop is consistently in the 65 - 70 degree range even with the -18 degree below zero we had this past week. This heater gets 5 stars from us.

Rated 5 out of 5 by from Great heater! This is every bit as good as all the review said, great product, lots of heat. Don't buy the cheap heaters...this is worth the money. Only problem was...I didn't know what kind of outlet to install for the plug, till the heater arrived, then found out it was just a "plain" 220 outlet.

Rated 5 out of 5 by from Exactly what we needed! My wife and I live in a house that was built in the 70's and never had a central unit installed. For years we've ran multiple 120v heaters in various places throughout the house (massive fire hazard I know!). On a recommendation from a family member I checked this heater out and am VERY glad I did. It came fully assembled in the box, all I had to do was plug it in. After paying an electrician $125 to wire a 240v plug in my living room, it was ready to go. I've now spent a total of $425 and my house (1400sq ft) is a comfortable 70 degrees with the new heater set just below the middle of it's dial. It cuts on and off with a decent degree of frequency and seems to be vastly more energy efficient than my previous heating arrangement (not to mention way safer!). Compared to the $8k I would need to have a panel upgrade and a brand new HVAC installation, $425 is pretty sweet to have this quality of heat in my home. If you are thinking to use this to heat a workshop or garage, I would assume you'll be very pleased indeed as it's currently heating my house just fine as I write this.
