Heaters | Frequently Asked Questions

Q:  What's the difference between the Vornado VH2 and DVTH?
A:  The primary difference is in the type of controls the units use. The Model VH2 (Vortex Heater) has a bi-metal thermostat and a "plus-to-minus" temperature control dial. The unit offers a selection of 1500 watts on "High" or 750 watts on "Low".  The thermostat will cycle the unit on and off as it reaches the point of heat selected on the dial on top of the unit.  Safety features on the VH2 model include an instant Tip-Over switch that cuts the power if the unit is tilted or knocked over and a cool-touch cabinet and grill.

It also features Over-Temp protection, which automatically shuts off the heat if the airflow is blocked, plus a backup fuse for an added layer of protection. The Model DVTH (Digital Vortex Heater)  features a thermistor, a sophisticated sensor that allows the unit to self-adjust the heat output to maintain the desired temperature. You select the temperature using the calibrated temperature control dial on the top of the unit. The DVTH  maintains a constant room temperature and eliminate annoying hot and cold cycles.  Because of the Thermistor, the DVTH uses only the necessary amount of energy to achieve the desired temperature: up to but not more than 750 watts on the "Low" setting, and up to but not more than 1500 watts on "High".  The DVTH also features a cool-touch cabinet and grill, Over-Temp protection that quickly throttles back heat output if the units airflow is blocked by objects or tipping over and a backup fuse for an added layer of protection.

Q:  How large of an area can I keep warm with my Vornado Heater?
A:  Because they not only heat the air but also circulate it, Vornado VortexHeat Heaters are more "comfort-efficient" than other comparably sized space heaters.  While it's very difficult to quote a particular room size, we can tell you that VortexHeat will effectively warm just about any room in an average home. (Be advised that VortexHeat is not recommended for use in bathrooms or similar wet environments.)

Q:  I work in a cold office. Is it safe to put my Vornado Heater under my desk?
A:  It's OK to run your Vornado Heater under a desk as long as you don't block the airflow path.  If the airflow is blocked, the Over-Temp safety feature will shut off the unit's heating element.

Q:  We have young children running around our house. Is it safe to use the unit when they're around?
A:  THERE IS NO SUCH THING AS A "CHILD SAFE" OR "CHILD PROOF" HEATER OR ELECTRICAL APPLIANCE. Vornado VortexHeat Heaters have been designed with a number of special safety features including a "cool-to-the-touch" exterior cabinet, over heat protection and tip-over protection.  In fact, our units are perhaps among the most "safety-focused" products in their category.  But just like a toaster, iron, hair dryer, etc., electric heaters are high wattage appliances.  Neither children nor people who may be incapacitated should ever be left unattended around a heater.

Q:  If your products are as good as you say, how will a Vornado you might introduce 10 years from now be any better than the one I have today?
A: Although the design principle used in our products is the same as it was 60 years ago when the O. A. Sutton Corporation made the first Vornadofans, technology has come a long way in the last half century.  We can only imagine what breakthroughs await in the new millennium.  Our research and development efforts never cease and we believe there is always room for improvement.
