I'm looking to heat my insulated garage (25x35) to keep it above freezing during a Wisconsin winter with this electric heater kept on the low setting all winter long. Does anyone have experience of how much that would increase my electric bill?
Pat K on Dec 10, 2013
Best Answer: I have the 7500W and a 20X26 garage with a 9 foot ceiling and only have it turned up less than 1/4 max. It is about 65 in there and it feels like 80. It's 10 degrees out with a minus 9 wind chill. My electric bill went up less than $10 a month......if that.

steve g on Nov 8, 2013
Best Answer: If the ceiling is closed off and insulated and the walls are insulated too then it will be ok. My garage has has insulated walls but the ceiling is open to the eaves and it's 24'x24' so it struggles to warm the entire room.

I have a 20x24 insulated garage I live in north east mn temps get to 40 below every year without the wind chill will this heater do the job to keep my garage from freezing?
A shopper on Dec 29, 2014
Best Answer: I live in missouri. We get zero to -10 at times without wind chill. I have a 20X26 garage. Insulated, with insulated garage door that I did. It was an uninsulated garage when installed. This heater wills do the job of keeping your garage from freezing in those temps, but I'm certain the unit will run non stop. The past few nights it has been in the teens without wind chill and I can easily hear the garage to 75 if needed. I am considering installing a ceiling fan for better circulation of the warm air. The thermostat on this unit did burn up on me. The unit is very good, but the t-stat is not. I bypassed it and installed a wall mounted stat. it works much better since I can reach it easier. I hope this helps to answer your question.

I have one of these and it quit working. about five years old or so. Fahrenheat FUH5-4.

Has 110v to each pole in the heater but wont work

any thought?
Bill h on Jan 22, 2014
Best Answer: If you do have 220 or 240 between line 1 and line 2 at the unit, then it appears thr problem is at the unit,
coulld be the thermostat ?

If it has a contactor, is it pulled in? If not then there is
a control problem. If you are skilled and confident you
could simply push the contactor in and it should
operate or have an electrician do it. Most of the time
you can bypass the thermostat and close the
contactor that way.

I haven't had any problems so far with mine.

Does this heater a plug in?
A shopper on Nov 19, 2015
Best Answer: Does this heater have a plug in?
No. You need to supply and install the hardware that connects it to whatever electrical source you plan to use. The maximum heat output is achieved using a 220V 30-amp circuit (for the FUH54C model). For this you need at least 10AWG wire between the heater and the the source's 2-pole circuit breaker. At the junction box for the heater you can either run a flexible conduit (metal clad is recommended) to carry the wiring to the heater's internal terminal block, or, you can equip the junction box with a 30-amp receptacle (like a dryer outlet) and attach a matching dryer line cord to the terminal block. That will allow you to plug in the heater to the junction box receptacle. The latter option is more expensive and probably unnecessary if you aren't planning to unplug and move the heater after it's installed. Note: the heater can be tilted to direct its output, so allow enough slack in the flexible conduit to do that when you install it.

Can this unit be mounted on a wall instead of the ceiling?
Alfred L on Aug 16, 2015
Best Answer: The manual states that if you are mounting from horizontal to 45 degrees, you need to maintain 13 inch separation from walls. I suppose you could mount a bracket on the wall and hang the heater from that. Hanging the heater from the ceiling itself is the simplest way to do it unless you just can't do that for some reason. I mounted a foot long 2 x 4 onto the ceiling and then hung the heater off of that. Also , the controls access panel is on the bottom so you can't set it on anything.

How much does it coast to use this product?
A shopper on Jan 22, 2015
Best Answer: During the month of December in Kansas temps ranged anywhere between 20's-40's for the high and sometimes single digits overnight. My utility bill was $270 and it is normally $130-150 during the winter months. The heater is installed in a 24x32 building with 10ft side walls. I only have the bubble wrap type insulation and no ceiling. During that month I maintained a inside temp of 50 degrees Fahrenheit on the low setting so I was very pleased with the performance of the unit and the utility cost was not bad considering what I was making it do. This is my first winter that I have had it and have since been keeping it off unless I know I will be in the shop so the wife stays happier.

can I wire this with a mail plug to be able to move it?
rickv v on Jan 11, 2015
Best Answer: I wired mine using a 220v welder power cord. Then I used a heavy duty welding extension cord in order to adequately reach my 220v outlet. It works well and the wiring is plenty heavy enough to carry the load.

A shopper on Aug 13, 2014
Best Answer: This heater is electric, so no venting is needed. There is a fan in the back of the unit that draws air and blows it across the heated coils to push heated air out the front of the unit. We installed two in a 20X 30 insulated shop. They do the job and keep the place warm in the winter when heat is needed.

What are the fire risks?
Thomas B on Jan 14, 2015
Best Answer: The fire risk for this heater are the same as any electric heater or appliance. Improper installation including undersized wire for the load or improper placement of the heater near combustibles can increase the risk of fire. Care should be taken when starting the heater for the first time each season to make sure an excessive amount of dust hasn't accumulated on the coils.

I Have a 36 x 36 garage what would be the best heater for this space?
A shopper on Nov 1, 2014
Best Answer: I live on the Cumberland Plateau in middle TN where it was 17 degrees last night so it gets fairly cold sometimes and I bought this same heater 2 years ago for a 6x16 area. It works great and my electric bill only went up ~$10/mo. So for your large garage I think this heater would run most, if not all, of the time especially if you live any further north of me. So your electric bill might go up another $100/mo but that would depend on how warm you want your garage and how often you would heat it of course.

Best Answer: I bought mine in December of 2013 and it came set up to be hard-wired with instructions on how to do so. I'm not 100% sure how it comes now but I'm going to guess it is still the same - hard-wired.

I'm considering getting this 5000W electric heater to heat my new garage 25' x 35'. The walls and ceiling will be insulated. I want to be able to always keep the temp above freezing in the garage during a Wisconsin winter by keeping it set on the lowest setting. Does anyone have experience with using this heater in that way and how much it increases your electric bill?
A shopper on Dec 10, 2013
Best Answer: Best way to run it is to install an external thermostat which will manage the operation of the heater better than the built in one which is pretty crude.
You can't guest the cost of increased heating because every jurisdiction charges a different rate. I imagine that in Wisconsin in the middle of winter it would cost you at least $50/month at say 50d, but it's simply a guest.
To calculate the therms you would use you have to run an energy audit that would calculate the cost based upon the cubic feet of the garage, R factor of the insulation and the desired temperature times the kilowatt hour rate that you're paying.

How many amps does this heater require?
A shopper on Oct 28, 2015
Best Answer: Apologies I don't know the actual amps as I installed it over a year ago. But I can tell you that you should be able to download the owners/installation manual to find out the required circuit for the unit on Blaine or manufacturers website. I can tell you I had no issues installing the power supply directly from the main breaker box and it has worked flawlessly since Jan 2014 here in Indiana.

For 30 amp breaker which jumpers stay in internal wiring?
A shopper on Feb 21, 2015
Best Answer: I have the FUH-54B Heater. Leave all of the jumper wires on the C-D terminal. There will be nothing on the A-B Terminal. This will give you 5000 watts and unit will pull just under 21 amps. Use at least 10 gauge wiring and a 30 amp two pole, two hundred forty volt breaker. Good Luck.

My garage was wired for an electric heater already but the old heater was removed before I moved in so I could not learn from removing the old item like I normally do. On the whip are 1 white that is neutral and two Blacks hot and one RED hot all tested with my wiggy. Is it as simple as using two hots to make 220 and the one white neutral to power this up to 220? I know I will have to upgrade the breaker from 20 to 30 amp.
Thanks for any help you may offer !
Maxxx on Jan 2, 2015
Best Answer: 1. You first need to confirm the existing wire is 10 gauge; I say this because a circuit protected by a 20 amp breaker is usually made of 12 gauge wire, and it is a fire hazard and NEC violation to install a 30 amp breaker to protect a circuit wired with 12 gauge wire.
2. The description of the whip conductors is perplexing too; this 240 volt heater should be attached to a whip that contains a black (hot conductor 1), a red (hot conductor 2), a white ('neutral'), and either a bare ground or green ground wire. There shouldn't be two black wires as well as a red wire (in addition to a white and green/bare wire).
3. Considering the nature of your question and description of the existing wiring, I would hire an electrician so the heater is installed correctly and safely.
