Why should I consider an Alien model rathar than the Deuce?
The Deuce is a great heater and we love it but our Alien models are between 3-6x faster than the Deuce.
The Alien X Turbo is a more portable model and ideal for overnight stays. We have found out that most FBOs will let you use their service hanger to plug in your heater right before you fly out since you would only be plugging it in for 30mins or so (depending on model) after an overnight stay.
All Alien models will continue to monitor the air in the engine compartment with less variance.
My heater seems to be on all the time, is there a problem with it?
Although the heating element will only be on when needed to heat up your engine to your desired temperature, your heater’s fan will always be on. The fan remains on to continue monitoring the air in your engine compartment and provide your thermostat with a more accurate reading of your engine’s temperature. Don’t worry, your fan alone only draws as much energy as a small lamp light bulb.
If the actual heating element (not just the fan) seem to be on all the time, check your thermostat. We find that this often happens when your thermostat is set at 90 degrees. It is very hard to keep an engine at 90 degrees in very cold weather, we recommend you set your thermostat at 70 degrees or lower if you will be leaving your heater unattended, 70 degrees is also an ideal temperature to start your engine safely.
If the fan stays on all the time, how much energy is my heater using?
The fan by itself only draws 25 Watts, that is similar to what a small lamp light bulb would use.
Will the Alien models work with my 2,000 watt generator?
Yes, the Alien and the Alien Turbo will. The Alien X and the Alien X Turbo are rated at 2,100watts and therefore are NOT compatible.
How many amps does an Alien model heater draw?
The Alien and the Alien Turbo draw 15 amps. The Alien X and the Alien X Turbo draw 17 amps.
I dropped my Alien model heater and it broke/cracked, is it covered under my warranty
It is important that you handle your unit with care. Aerotherm's 3yr warranty covers malfunction of your heater due to manufacturing or mechanical defect or failure and it does not cover breaks or cracks caused by dropping the unit or malfunctions due to misuse.
How is the Deuce Different?
The Deuce is the only model we carry that is customizable to switch between 800 and 1600watts making it the perfect heater for twin engine aircraft.
What are the heating times on a cold-soaked engine?
Depending on the model of heater you have the heating times can vary between 30mins - 3hrs. Please refer to our comarison chart for more information.
How does the AeroTherm heater attach to my airplane?
Every AeroTherm heater ships with a durable nylon suspension band that attaches to the prop of your aircraft.
Can the heater be used on any plane?
The heater can be used on virtually any small aircraft, as long as the cowl vents will accommodate a 4inch diameter semi-collaspable hose. To maximize warming, the cowling/engine compartment should be sealed with the provided sponges. SEALING IS IMPORTANT! You can cook a pie with the oven door open, but it will take a lot longer. We also suggest using a blanket or something as simple as a sleeping bag to help retain the heat. This simple step increases efficiency tenfold.
Can the AeroTherm heater be run on a timer?
The AeroTherm Heater has a built-in thermostat which will cycle on and off as needed. Some pilots do use a timer when they have consistant flight schedules this allows them to turn on and run the heater on a as needed basis.
How big is the Deuce?
6.5" H x 6.5" W x 12.75" L
Will the AeroTherm heater be effective if my plane is parked outside in the wind at extremely cold temperatures?
Yes, if you cover the engine compartment with an insulated blanket and make sure your bottom cowl holes are plugged. (Always remember to remove cowl plugs before flying)
How much electricty will the Deuce utilize?
6.9 Cents per kilowatt hour (SD Utility Rate- Individual rates vary by Utility)
Deuce Draws 1355 watts.
1355 watts x .0069 = 9.35 cents/hr
Our most recent testing took place on a Cirrus without a blanket inside an unheated hanger at 20 degrees Fahrenheit. The Deuce was plugged into an hourly electric meter and set for 70 degrees. It ran for 6 hours over a 21 hour period essential 1/3 of the time the unit was running.
9.35 cents x 6 hours = 56.10 cents an hour
56.10 cents / 21 hours = 2.67 an hour or 2.67 x 24 = 64 cents a day.
Results may vary based on temperature, hangar, airplane fabrication and utility rates.
My RCS stopped working suddenly, what is wrong with it?
Please check your T-mobile account online. Your account information was sent to you with your unit. If you have misplaced your information please call us. It is very important that the phone number assigned to your RCS remains active. If you find that your number is no longer active you will need another SIM card. If you need another SIM card call us, we will send you one for our cost of $35.
If you have found that your account with Tmobile is still active and you have enough credit for your RCS to continue working but your RCS is still not working, please check our next line of questions.
One (or both) of the relays are not running the programmed length of time, what is wrong?
Depending on the type of product/appliance that is plugged in, it may have generated too much heat causing board failure. If you are running an appliance or an Aerotherm heater drawing more than 12amps, the RCS should be programmed for 3hrs or less to avoid this problem.
If your RCS has had board failure, call us to get your unit replaced.
I am not receiving a text response from my RCS, what is wrong?
Have you recently changed your phone number? If so, make sure you add your new phone number to the admin and white list. Instructions on how to add a phone number to the admin and white list were sent with your unit. If you’ve misplaced the instructions give us a call or check the documentation (also availble on our website).
Check signal strength. You should always check your signal strength when setting up your RCS at a new location, you may do so by calling or texting the RCS while on location to confirm it has good signal strength. If you find that you have weak signal and your RCS is not receiving your text or call, you may have the need for a magnetic antenna (we have them in stock). Although a weak signal could be a problem it’s not a common one. 9 out of 10 of our customers usually have enough signal strength to have their RCS operate properly.
Can I use a carrier other than T-mobile for my RCS?
Yes, you may use a different carrier as long as it operates on the GSM network. AT&T and Tmobile are the only GSM carriers in the U.S. All carriers in Canada opperate on the GSM network.
*** If you decide to use another carrier or get a new Tmobile SIM that was not provided by us, you must deactivate the voicemail feature for your SIM card to operate your RCS properly.
My heater fan has stopped or is making a squawking noise
Given the design of the heater and depending on how it is used and in what conditions it is subjected to, some of the units will need to be lubricated. These maintenance instructions can be found in PDF format under the How To Use section of this website.
